  [0003] The present invention is in the field of gravity toilets for the removal of humans and other waste. The invention further relates to the field of toilets operated by a primed water delivery system to improve performance.

  [0004] Toilets for removing waste, such as human waste, are well known. Gravity toilets generally have two main parts: a tank and a bowl. The tank and bowl may be separate components that are joined together to form a toilet system (commonly referred to as a two-piece toilet), or may be combined into one integral unit (typically referred to as a one-piece toilet). Be performed).

  [0005] A tank, typically located at the back of the bowl, initiates a flushing action of waste from the bowl to the sewer and contains water used to refill the bowl with fresh water. When the user wants to flush the toilet, he pushes down a flush lever on the outside of the tank, which is connected to a movable chain or lever inside the tank. When the flush lever is depressed, it moves a chain or lever that serves to lift and open the flush valve inside the tank, causing water to flow from the tank into the bowl, thereby initiating a toilet flush.

  [0006] There are three general purposes that must be fulfilled in a wash cycle. The primary purpose is the removal of solids and other waste into drains. A second purpose is to wash the bowl to remove solid or liquid waste deposited or adhered to the surface of the bowl, and a third purpose is to remove relatively clean water from the bowl between uses. This is to replace the amount of water before washing in the bowl so that it remains inside. The second requirement, bowl cleaning, is typically accomplished using a hollow rim that extends over the upper circumference of the toilet bowl. Some or all of the rinsing water is directed through the rim channel and flows through openings located therein to sprinkle the entire surface of the bowl to perform the required cleaning. A third requirement is to refill the bowl with clean water, thereby restoring the sealing depth against sewage gas backflow and preparing for the next use and flush.

  [0007] Gravity toilets can be divided into two general categories: flush-type and siphon-type. In a flush toilet, the water level in the bowl of the toilet is always relatively constant. When the flush cycle starts, water flows out of the tank and overflows into the bowl. This causes a rapid rise in the water level, with excess water spilling over the trapway weirs and carrying liquid and solid waste therewith. At the end of the flush cycle, the water level in the bowl naturally returns to a balanced level determined by the height of the weir.

  [0008] In siphon-type toilets, the trapway and other hydraulic channels are designed so that the siphon is started in the trapway after water is added to the bowl. The siphon tube itself is an inverted U-shaped tube that draws water from the toilet bowl into the sewage pipe. When the flush cycle is initiated, water flows into the toilet bowl and spills over the weir in the trapway faster than it can exit the outlet to the sewer. Eventually, enough air is removed from the lower leg of the trapway to start the siphon, which then draws the remaining water out of the bowl. When the siphon breaks, the water level in the bowl is consequently well below the level of the weir and at the end of the siphon flush cycle, the bowl is refilled with water to protect against the original water level and backflow of sewage gas. A separate mechanism needs to be provided to re-establish "sealing".

  [0009] Siphoned and flush toilets have inherent advantages and disadvantages. Siphon toilets tend to have a smaller trapway due to the requirement that most of the air must be removed from the lower leg of the trapway to start the siphon, which can result in clogging. Flushable toilets can function with large trapways, but generally, the 100: 1 dilution level required by piping regulations in most countries (ie, 99% of the pre-flush water in the bowl is (Which must be removed from the bowl during the flush cycle and replaced with fresh water) requires a smaller amount of pre-flush water in the bowl. This small pre-rinse volume appears as a small "water spot". The water spot, or surface area, of the pre-flush water in the bowl plays an important role in maintaining toilet bowl cleanliness. Large water spots increase the probability that waste will come into contact with water before contacting the ceramic surface of the toilet. This reduces effluent sticking to the ceramic surface, thereby making it easier for the toilet bowl to self-clean with a flush cycle. Flushable toilets with small water spots therefore often require manual cleaning of the bowl after use.

  [0010] Siphon toilets have the advantage that they can function with a higher pre-flush water volume and a larger water spot in the bowl. This is possible because the siphon action pulls most of the pre-flush water volume from the bowl at the end of the flush cycle. When the tank is refilled, a portion of the refill water is directed into the bowl, allowing the pre-flush water volume to return to its original level. In this way, the 100: 1 dilution level required by many plumbing rules is achieved even when the starting volume of water in the bowl is significantly higher than the flush water leaving the tank. In the North American market, siphon toilets are widely accepted and are now regarded as the standard, generally accepted form of toilet. In the European market, flush toilets are still more accepted and popular, while both versions are common in the Asian market.

  [0011] Gravity siphon toilets can be further divided into three general categories, depending on the design of the hydraulic channels used to achieve the flushing action. These categories are non-jet, rim-jet, and direct-jet.

  [0012] In a non-squirt bowl, all of the wash water exits the tank and enters the bowl inlet area, flows through the main manifold and enters the rim channel. Water is sprinkled around the bowl through a series of holes located below the rim. Some of the holes may be designed to be larger in size to allow more water to flow into the bowl. Relatively high flow rates are required to displace enough air in the lower leg and flood the water over the trapway weirs quickly enough to start the siphon. Non-blowout bowls typically have good enough performance for bowl cleaning and pre-flush water exchange, but relatively poor performance for bulk removal. The supply of water to the trapway is inadequate and turbulent, thereby sufficiently filling the lower leg of the trapway and making it more difficult to start a strong siphon. As a result, non-squirt toilet trapways are typically smaller in diameter and include bends and constrictions designed to impede water flow. Without a smaller size, no bends, and no constrictions, a strong siphon is not achieved. Unfortunately, the smaller size, bends, and constrictions result in poor performance, frequent clogging, and very unsatisfactory end-user satisfaction with large amounts of waste removal.

  [0013] Toilet designers and technicians have improved the bulk waste removal of siphon-type toilets by incorporating a "siphon outlet". In a rim-spouted toilet bowl, flush water exits the tank, flows through the toilet inlet area, flows through the main manifold, and enters the rim channel. A portion of the water is sprayed around the bowl through a series of holes located below the rim. The rest of the water flows through the ejection channel located in front of the rim. The spout channel connects the rim channel to a spout opening positioned in the bowl sump. The spout opening is sized and positioned to direct a strong flow of water to the trapway opening. When water flows through the spout opening, this serves to fill the trapway more efficiently and quickly than can be achieved in a non-squirt bowl. This faster and faster flow of water into the trapway allows the toilet bowl to be designed with a larger trapway diameter and fewer bends and constrictions, which is less than a non-blowout bowl. Improve performance in bulk waste removal. Although less water flows out of the rim of the rim-spouting toilet bowl, the bowl wash function is generally acceptable because the water flowing through the rim channel is pressurized by the upstream flow of water from the tank. is there. This allows the water to exit the rim hole with higher energy and perform a more effective job of cleaning the bowl.

  [0014] Rim-spouted bowls are generally superior to non-spouted, but the long passageway through which water must travel through the rim to the spout opening dissipates and wastes available energy. . Direct blow bowls can improve upon this concept and provide better performance with respect to bulk removal of waste. In a direct blow bowl, the flush water exits the tank, flows through the bowl inlet, and through the main manifold. At this point, the water flows through two parts, the main purpose of achieving the desired bowl cleaning, through the rim inlet port to the rim channel, and through the spout inlet port and through the main manifold. It breaks down into a portion that leads to a "direct spout channel" that connects to the spout opening in the sump bowl sump. Direct squirt channels can take a variety of forms, sometimes unidirectional around one side of the toilet bowl, or "double-fed", where symmetrical channels travel on both sides Then, the manifold is connected to the ejection opening. As in the case of the rim spout bowl, the spout opening is sized and positioned to direct a strong flow of water to the trapway opening. When water flows through the spout opening, this serves to fill the trapway more efficiently and quickly than can be achieved in a non-spouted or rim-spouted bowl. This more vigorous, faster water flow to the trapway allows the toilet to be designed with even larger trapway diameters and minimal bends and constrictions, which are non-squirting. Improves performance in bulk waste removal compared to bowls and rim-blowing bowls.

  [0015] Although direct-feed spout bowls currently occupy a large portion of the state of the art for massive waste removal, there remains a major area for improving toilet performance. Government authorities have continually called for reducing the amount of water used by urban water users. In recent years, much of the interest has been to reduce the water demand required by the operation of the toilet flushing operation. To illustrate this point, the amount of water used in the toilet bowl at each flush was determined by the government to be 7 gallons / 1 flush (prior to the 1950s) to 5.5 gallons / 1 flush (late 1960s), 3 It has been gradually reduced to 5.5 gallons / water wash (1980s). The National Energy Policy Act of 1995 currently requires toilet bowls sold in the United States to use only 1.6 gallons / wash (6 liters / wash) of water. Recently, regulations have been passed in California requiring water usage to be further reduced to 1.28 gallons per flush. The 1.6 gal / l flush toilet currently described in the patent literature and commercially available loses its ability to consistently siphon when reduced to such lower levels of water consumption. Manufacturers are therefore forced to reduce and continue to reduce the diameter of the trapway, at the expense of performance without the development of improved technology and toilet designs.

  [0016] Some inventions have aimed to improve the performance of siphon toilets through optimization of the direct squirt concept. For example, in U.S. Pat. No. 5,918,325, siphon toilet performance is improved by improving the shape of the trapway. In U.S. Patent No. 6,715,162, performance is improved using a flush valve with a semi-curved inlet and an asymmetric flow of water into the bowl.

  [0017] US Patent No. 8,316,475 B2 discloses a pressurized rim that allows enhanced washout and proper siphoning for using low volumes of water that meet current environmental water use standards. And has demonstrated the configuration of a direct feed blast.

  [0018] US Patent Application Publication No. 2012/0198610 A1 discloses a control element in a main manifold that divides the flow of wash water entering a toilet manifold from a tank inlet into an inlet port of a rim and into an inlet port of a direct feed jet. The high performance toilet bowl achieved by is also shown. U.S. Pat. No. 2,122,834 shows a toilet bowl with an air manifold and a hydraulic manifold for introducing air into the toilet flush cycle to terminate siphoning and prevent backflow into the system. I have. Other inventions attempt to address the performance between the rim and the spout by dividing the toilet tank into separate sections. See U.S. Pat. No. 1,939,118.

  [0019] Minimizing turbulence and flow restrictions in the interior channels of the toilet bowl is of paramount importance when the flush volume is pushed below about 6.0 liters. One of the most important factors in minimizing turbulence and restrictions on flow is the management of the air occupying the rim and ejection channels prior to initiating the flush cycle. If air cannot escape from the system before the flushing water rushes, it will occupy space in the channel and continue to restrict flow. U.S. Pat. No. 5,918,325 discloses a toilet bowl having an air discharge means, i.e., a passage connecting the jet channel to the rim, and allowing the air to escape from the jet channel into the rim during flushing. Is explained. U.S. Patent Application Publication No. 2012/0198610 A1 also discloses a toilet bowl with a downstream communication port that allows air and / or water to pass between the ejection channel and the rim channel.

  [0020] There remains a need in the art to further improve siphon toilet performance, and in particular to manage pre-flush air occupying the spout channel. There is also a need for a toilet bowl that ameliorates the disadvantages noted above in prior art toilet bowls by reducing clogging and enabling significantly improved cleaning during the flushing operation without sacrificing flush performance. Present in the technical field. Such toilet bowls should also still meet water saving standards and government guidelines, while providing sufficient siphons for low water consumption to various trapway geometries.

Unless otherwise stated to the extent that similar features of the present invention are referred to and, thus, describe alternative constructions of a particular feature, those skilled in the art will recognize, based on the present disclosure and its accompanying drawings, one such feature. Will be understood to be applicable to other embodiments that describe similar features.

  [0164] In the present invention, a fluid introduced into the bowl assembly to deliver different amounts of fluid from the squirt flush valve and the rim valve, such as a rim flush valve, preferably through a separate closed squirt fluid path. A siphon flush toilet assembly is provided that is operable to maintain a primed closed squirt fluid passage including a squirt channel by isolating the flow. It operates in an air-filled blast channel and provides more powerful performance compared to a standard gravity-flush siphon toilet bowl that must expel air to minimize turbulence and flow restrictions.

  [0165] The toilet bowl assembly of the present invention has a closed squirt fluid path that includes a squirt channel in the toilet assembly outside the bowl. The ejection channel has a bowl-forming geometry, including an optional ejection manifold, as long as the closed ejection fluid path receives fluid from the ejection valve outlet into the ejection inlet port and through the ejection channel to the ejection outlet port. Depending on the geometry, it may have various configurations and extension areas, additional ports or side channels, and the like. The closed squirt fluid path keeps the squirt channel permanently primed and substantially isolates it, thereby helping to prevent air from entering the squirt channel. . This involves (1) isolating the bleed channel from the rim flow or other passage to the atmosphere, and (2) closing the bleed channel flush valve before the water level in the tank drops to the level of the flush valve opening. This helps (3) prevent airflow from entering the ejection channels and any other ejection channels, areas, or optional ejection manifolds when used, which in one embodiment is air By establishing a sealing depth in the squirt trap in the sump area to assist in blocking the squirt from entering the squirt channel outlet, and / or (4) the water level in the squirt trap is This is accomplished by configuring and operating the assembly to reverse the air and ensure that it does not fall to a level that can enter the ejection channel.

  [0166] In general, the ratio of the amount of fluid to the rim to the amount of fluid to the spout also affects toilet performance. In a typical prior art siphon squirt toilet, about 70% of the fresh water is needed to power the squirt and start the siphon and only about 30% to wash the bowl through the rim. leave. With the priming toilet herein, much less water is required to initiate the siphon, thereby allowing more water to be used to clean the bowl. Applicants have determined that greater than about 50% of fresh water can be directed to the rim due to significant improvements in toilet flushing. In a preferred embodiment, more than about 60% and as much as about 70% of the water can be directed to the rim.

[0167] In addition to the elements noted above, another means for maintaining a sufficient sealing depth of the water in the sump area and / or preventing backflow of air from the sump into the ejection channel. The method is to keep the water flowing through the squirt channel more slowly after breaking the siphon. For example, in a bowl filled to a weir (ie, there is extra water contributing to the siphon), to initiate and maintain the siphon in a trapway of approximately 54 mm in diameter, a spout greater than about 950 ml / s Requires a volume flow from the unit. This translates into a linear flow of 127 cm / s over the 7.47 cm ² spout outlet port area. The larger the trapway size, the higher the flow rate required to initiate and maintain the siphon, and the smaller the trapway, the smaller the value. The siphon breaks when the flow from the jet is reduced to less than about 950 ml / s. By maintaining a volumetric flow from the orifice of less than about 950 ml / s and greater than about 175 ml / s (ie, a 23.4 cm / s linear flow through the 7.47 cm ² area of the outlet port) Air is prevented from entering the closed ejection channel. When the bowl is completely filled to the level of the trapway weir, the flow from the spout is stopped without losing priming as long as the top of the spout channel is located below the trapway weir. obtain.

  [0168] Controlling such flush valve actuation for the squirt flush valve and the rim flush valve can be done in a number of ways. One method uses a solenoid valve as disclosed in U.S. Patent Application Publication No. 2009/0313750 and U.S. Patent No. 6,823,535, the relevant portions of which are incorporated herein by reference. It is because of that. This valve control method is a mere mechanical method, such as a dual inlet flush, such as that disclosed in US Pat. No. 6,704,945, the relevant part of which is also incorporated herein by reference. This can be achieved by modifying the valve. Alternatively, a flush actuation bar may be used that is balanced for optimal performance of the two flush valves in sequence as shown herein.

  [0169] The flush actuation bar may be connected to a rotating rod and handle, or to another flush actuator using an adjustable flush connector. The adjustable flush connector provides an adjustable connection that compensates for differences in the placement of the rotating rod with respect to the valve assembly in the toilet bowl. This compensation allows most valve assemblies, flush actuation bars, and / or rotating rods to fit together. Adjustments made by the adjustable flush connector may include longitudinal movement along its length, rotation about its longitudinal axis, and / or rotation about its transverse axis.

  [0170] Further, as discussed in more detail below, system performance may be enhanced by providing a "peel off" valve cover to facilitate automatic priming of the jet. The cover serves to reduce the actuation force required to open the blast flapper. In the present invention, where the ejection channel is primed, the weight of the water both above and below the flapper requires more than twice the force than a conventional flapper valve. By peeling and opening the cover, the seal breaks and some water comes in, while the air retracts so that the cover opens more easily. In addition, during the first priming, if the valve is closed, the spout will be filled with air, and if the flapper suddenly opens, fresh water will rush too quickly, and the air in the spout channel will And depending on the geometry of the ejection channel, it may be trapped and not sufficiently expelled. Further, the embodiments herein include a primed and closed squirt path, so that when the toilet bowl needs a water rush, the optional anti-reflux device, as described further below, will provide a squirt. A flush valve may be provided.

  [0171] A preferred valve cover structure for use with a "peel off" valve cover may optimize valve performance. In particular, a locking element can be provided on the seal to prevent the seal from coming off the valve cover. In addition, valve assemblies may be provided that are associated with each other using a link device to maintain consistent flush performance. Such a valve assembly can be used to ensure proper and consistent alignment between valve bodies over time.

  [0172] Sufficient post-flush depth in the sump area and / or stopping water from entering the closed squirt fluid passage through the squirt outlet port can be achieved while the siphon is breached. It can also be achieved by keeping the water flowing through the rim channel on the rim shelf or in older toilet designs. Since the toilet system described herein includes separate channels and valve mechanisms to control the flow to the rim and the spout, the system will allow the flow through the rim inlet port while the siphon is torn. Can be designed to continue. Water flow to the rim inlet port is preferably sufficient to maintain the water level in the sump area above the height of the spout outlet port, but not enough to maintain the siphon in the trapway It is. In this way, additional safety precautions may be taken to keep air out of the bleed channels, and reliance on the sealing depth in the sump area may be reduced. It should also be noted that the flow through the jet and rim can be utilized together to maintain sufficient post-flush depth in the sump area.

  [0173] A related field in which the present invention provides an improvement over the prior art is in high efficiency siphon toilets with a flush volume of less than 6.0 liters, preferably less than 4.8 liters. Embodiments of the inventive toilet bowl assembly described herein provide less than about 6.0 liters per flush in a single or dual flush toilet assembly while cleaning the bowl extremely with low water usage. It can maintain a resistance to clogging consistent with today's toilets, preferably less than about 4.8 liters per flush. Since much less water needs to be passed through the squirt channel to initiate a siphon, embodiments of the priming toilet assembly herein can work with less than about 4.8 liters per flush. Preferably, it enables the production of a very efficient toilet bowl that can function at about 3.0 or less per flush and on the order of about 2.0 liters per flush.

  [0174] Furthermore, a second related area where the present invention provides improvements over the prior art is in siphon toilets with larger trapways. By changing the size of the trapway, water consumption and toilet performance are significantly affected. In the present invention, the lavatory bowl assembly comprises It can be kept primed in siphon toilets of various trapway sizes and volumes, which allows the toilet bowl assembly to maintain good flushing action and flushing capacity.

  [0175] To achieve the full potential performance of the toilet system of the present invention, the closed fluid spout must be "primed", ie, filled with water and containing little or no air. Don't go out. When the closed fluid ejection paths and ejection channels contain significant amounts of air, such as after initial installation of the toilet bowl or after major repairs or maintenance, the closed ejection channels can potentially increase the potential of the system. They must be primed before they can perform at full performance. In order for priming to occur, two basic requirements must be met: (1) allowing water to flow into a closed fluid ejection path faster than exiting a closed ejection channel; And (2) with respect to air contained within the ejection channel and the closed ejection fluid path, through the flow of water into the closed ejection channel, with or with the flow of water, Escape routes must be provided for the flow.

  [0176] The simplest method of priming a closed ejection channel, which can be referred to as "manual priming," is to leave the rim valve closed and obstruct or partially obstruct flow from the ejection outlet port. Opening the squirt flush valve assembly described herein. The squirt flush valve should be kept open until air bubbles escape from the channel into the tank and are no longer visible, at which point the squirt flush valve is closed and the obstruction of the spout outlet port is blocked. Can be released. Then, after refilling the tank, the system should be fully primed and ready to use with potentially the full performance possible. In a preferred embodiment, the system is designed to autoprime over the first few flushes after installation or after loss of priming for other unexpected reasons (such as maintenance, repair, etc.). Again, the same two requirements must be met for automatic priming, but are system specific. Ensuring an automatic priming system is solely dependent on the geometry and design of the flush flush valve, the closed fluid flush path including the flush channel, and the flush outlet port. As will be described in more detail below, the flush flush valve preferably allows high flow rates to enter the closed flush channel and increases flow rates (US Pat. A flush valve with a radius (such as that described in US Pat. No. 8,266,723) may be used. In most closed blast channel designs, the last part of the air entrained in the blast channel can rise to the space just below the flapper (or other opening mechanism) of the blast flush valve. Therefore, the valve design must also facilitate the escape of this residual air. As explained below, a gradually opening valve, such as a peelable flapper, can constrain the flow of water to one side of the valve and facilitate the escape of air around this flow. Certain patterns or ribs in the throat portion of the flush valve may also facilitate the escape of air in this manner.

  [0177] FIGS. 1-15, 17-19, and 29-34 illustrate a first embodiment of a toilet bowl assembly, generally referred to herein as assembly 10. FIG. Assembly 10 includes at least one flush flush valve assembly 70 having a flush flush valve inlet 71 and a flush flush valve outlet 13.

It can also be appreciated that may be used in the embodiments described herein (see FIG. 16 and embodiment 110). Such a rim may or may not be pressurized and may have various features as described in further detail below with respect to embodiment 110. The rim features of embodiment 110 can be incorporated into the rimless version shown in FIGS. 1-13 or 28 without departing from the scope of the invention.

  [0182] In the assembly 10 as noted above, the shelf 17 may be embedded. As shown in FIGS. 30-34, the shelf 27 has a relatively constant, preferably constant, depth d measured transversely into the contour from the interior surface of the toilet bowl, And a height h measured longitudinally from 27 to an upper surface 47 above the shelf.

Resized to form a deeper shelf in an area having a shelf width s1 and a height h1 somewhat larger than its depth to accommodate the strong flow of fluid from the rim inlet port, and Maintains a moderately sized shelf at a location approximately midway between the rims (see FIG. 31), with the rim flowing to the front of the bowl as shown in FIG. Continue along the ledge (see s2 and s3). The depth d is relatively constant, but the height h begins to extend towards the front of the bowl when the width of the shelf decreases (see for example s2 and s3) (heights h2 and h3 reference). Preferably, the depth in one embodiment herein remains between about 10 mm to about 30 mm. The height varies from about 35 mm to about 50 mm at the beginning of the flow, about 35 mm to about 50 mm at the midpoint between the rear and front of the bowl, and about 40 mm to about 55 mm at the front of the bowl. The shelf width is illustrated by s, where s is the tangent from a first radius of curvature r at the embedded edge of the shelf to a second radius of curvature R at which the shelf tilts downward. A cross-sectional measurement obtained by measuring along. The shelf is at an angle α with a tangent from the first radius. The angle α in this embodiment varies and is 7 °, 5 °, 7 °, 22 ° and 31 ° respectively as the shelf progresses along the path in FIGS. 30-34 as shown. . As the angle increases, the radius increases and the shelf width s disappears toward the downward slope when the shelf terminates.

  [0183] The depth d remains constant as the flow continues as shown in FIG. 33 from the front of the bowl to the opposite side of the bowl at an intermediate point that progresses toward the rear of the bowl of FIG. However, the height extends further from about 45 mm to about 60 mm at the midpoint in FIG. 33 to the rear of the bowl, where it is about 50 mm to about 65 mm. As the height increases (h4 and h5), the shelf 27 reduces to a curve and eventually terminates.

Flows here. The squirt trap has a sealing depth as described further below. For example, the sealing depth, the ejection path, and the measurement of the depth x as described in the embodiment 10 shown in FIGS. 1 to 13 and FIGS. 29 to 34 are described below. All modifications are easily incorporated and operative in the embodiment 110 of FIG.

  [0190] To maintain a siphon flush toilet assembly, such as the assembly 10, primed, the first steps are described above and include the present description, including 110, 1010, 210, 310 and 410, and the like. To provide a toilet bowl assembly having features as described with respect to various other embodiments of the present invention, particularly where a closed squirt fluid passage 1 having a squirt channel 38 therein includes a squirt flush. Extending from the outlet 13 of the valve 70 to the outlet 42 of the jet 20 such that, after priming, the closed jet fluid passage is closed by the air before and after the flush cycle is activated. Can be left primed with a fluid to keep out of water. The flush cycle is activated by any suitable actuator, such as the flush handle H. In a preferred embodiment, the outside of the ceramic and the handle H are formed from or incorporate a material that provides an antimicrobial surface. After the flushing cycle is initiated by the flushing device, such as the handle, the handle has a portion operably connected to the flushing bar 75 (which may or may not be removable).

  [0191] The valve can have an actuator that can both be opened at the same time (this can be done using the standard actuation bar of the flush handle) or provide a balancing approach in FIG. By using a flush actuation handle such as the one described above, it is possible to have a lifting timing change and / or adjustment based on the weight of the respective flush valve cover. As best shown in FIG. 15, the handle H is operatively connected to a rotating rod P having a rotatable moving link mechanism RL. Any hinges, pin connections, washers, or other rotating connectors may be used. The flushing operation bar 75 has a balance point BP for a movable connection with the rotating rod P through the link mechanism RL. A similar movable and rotatable link mechanism RL '(which may be the same as the rotatable link mechanism RL) connects the rotating rod and its link mechanism RL to the flushing operation bar 75 at a balance point BP. The balance point is selected by the design which works with the flush valve to finely and mechanically adjust the opening time of each valve when the handle H is depressed to activate the flush cycle. When the handle H is pushed down, the rotating rod P and the link mechanism RL are pushed upward at the end having the link mechanism RL. This in turn pulls the actuation bar 75 up. It is possible to provide a bar 75 having a plurality of holes in order to achieve a variable equilibrium point linkage, whereby only one bar needs to be manufactured, the weight of the various valve covers and the flushing Can be used for timing patterns. Although the flush actuation assembly is described with respect to a siphon flush toilet, it is understood that the flush actuation assembly can be used with any style of flush toilet, including a flush toilet.

  [0192] An assembly kit 1100, such as that shown in FIGS. 69-70 and 85, may be provided to improve actuation and communication between the handle H and one or more valves. The assembly kit 1100 may include a flush actuation assembly 11144 that includes a rotating rod P, a flush actuation bar 1175, and a connector 11260. One end 11142 of the rotating rod P may be connected to a handle H located outside the tank, or another flushing mechanism, while the opposite end 11143 of the rotating rod P is , May be connected to the connector 11260 using a rotatable connection. The rotating rod P may be a standard or conventional rotating rod, or may be adjusted to the size and configuration of the tank. As shown in FIG. 85, the arrangement of the connecting element 11145 on the rotating rod P, which may be one or more openings, depends on the valve opening determined by the manufacturer of the rotating rod, or the rotating rod with respect to the toilet tank. May be positioned at different locations along the line. Each manufacturer may have a slightly different arrangement for the connecting elements 11145 along the length of the rotating rod P, or the shape of the rotating rod P itself may be changed. Variations of the embodiments described herein for connector 11260 may be used to compensate for different placements of the connecting elements, and as such, substantially any rotating rod P, Still other non-conventional flush actuators are contemplated to be compatible with embodiments of the present invention. Variations of the embodiments of the connector described herein are due to differences in the configuration of the handle and the rotatable rod, and / or due to differences in the tank size, of the handle H and the rotatable rod P relative to the valve bodies 1131 and 1121. It can also help counteract the effects of differences in precise positioning. As such, the connector may ensure that an appropriate amount of lift is provided to the valve to trigger the desired actuation.

  [0193] As shown in FIG. 85, the connector 11260A includes a connecting element 11145 in the rotating rod P at a first chain end 11264 that forms a first rotatable connector 11153, and a second Shown as a chain C3 hooked to the connecting element 11261 on the flush actuation bar 1175 at the second chain end 11266 forming the rotatable connector 11157 of FIG. The flush actuation bar 1175 and the pivot rod P may, in each variation of the embodiment, be coupled to the flush actuation bar described in more detail below with respect to the use of the adjustable flush connector 11150 as illustrated in FIGS. And the same as the rotating rod. Depending on the type of connector 11260 used, the connecting elements on the rotating rod, and the connectors can be varied to form a rotatable connection between these elements. The connector 11260 allows at least a partial rotational movement about the longitudinal axis LAc (FIG. 85) to cause the flush actuation bar 1175 to rotate about the axis LAc with respect to the rotating rod P, but the rotating rod P It should be configured so that it does not rotate around. In addition, the first rotatable connector 11153 between the rotating rod P and the connector 11260 should be rotatably positionable about the transverse axis TAp of the rotating rod P. A second rotatable connector 11157 between the flush actuation bar 1175 and the connector 11260 should be rotatably positionable about the transverse axis TAb of the flush actuation bar 1175. Preferably, connector 11260 is an adjustable flush connector 11150, as shown in FIGS. 69 and 70 and described in more detail below. An additional variation of this embodiment of the connector that is sufficient to effect a rotational movement of the flush actuation bar 1175 with respect to the rotating rod P is also an acceptable connector and is shown in FIGS. 86 and 87.

  [0194] FIGS. 86 and 87 illustrate additional variations of connectors 11260B and 11260C that cause rotational movement about longitudinal axis LAc. The rotational movement of these variants of the connector about the longitudinal axis LAc is provided by a ball / socket connector 11154, which is preferably arranged along the length lc of the connector at the longitudinal center point LC. Similar ball / socket connector 11154 is described in further detail below with respect to one variation of embodiment 1100 that uses adjustable flush connector 11150 shown in FIG. 69 as an alternative to connector 11260. With reference to FIG. 87, a spacer 11262 may be positioned between the ball / socket connector 11154 and the flush actuation bar 1175. The spacer 11262 may be provided to allow the flush actuation bar 1175 to more easily rotate about the longitudinal axis, but is not required for the connector to function properly.

It is understood that any connection between the connector 11260 and the rotating rod P that allows the rotating rod P to rotate about the transverse axis TAp can be used. Similar connections between the rotating rod P and the connector 11260 are described in further detail below with respect to the adjustable flush connector 11150 of FIGS.

  [0196] Similarly, a second rotatable connector 11157 between the flush actuation bar 1175 and the connector 11260 is connected to the connection used for the first rotatable connector 11153 between the connector and the rotatable rod. They may be the same or different. As shown in FIGS. 86 and 87, a hinge-type connection 11268 may be used, where the protrusion 11263 is integrally formed on the connectors 11260B and 11260C. These protrusions 11263 may be inserted into the openings 11165 in the flush actuation bar 1175 by spring and / or torsional compression of the protrusions and / or the sides of the flush actuation bar. The flush actuation bar 1175 can rotate freely about the horizontal axis TAb of the flush actuation bar. Second rotatable, including the use of pins passing through openings in both elements, hooks inserted into the openings, ball joints, and other known or later developed rotatable connections Additional types of connection devices that are suitable for use with the various connectors 11157 are also contemplated. Similar connections between connector 11260 and flush actuation bar 1175 are described in more detail below with respect to adjustable flush connector 11150 of FIGS.

  [0197] Although several exemplary variations 11260A-11260C of the connector are described herein, the connector 11260 providing a rotational movement about the longitudinal axis LAc may be used in a flush actuation assembly. Is understood. Such rotational movement may be able to position the flush actuation bar in position and actuate the valve assembly.

It is understood that any type of connector that allows for it can be used. It is also understood that the adjustable flush connector 11150 may be a single unit that does not allow for movement or rotation between the first section 11151 and the second section 11152.

[0202] Each of the first section and the second section may be made independently of either a polymeric material or a metal, preferably they are made of dissimilar materials to prevent the mating parts from bonding. The first section 11151, which includes certain ball / socket connectors 11154, is preferably molded as a single unit from a polyester material. The second section 11152 is preferably formed from an acetal material. Other polymers, as well as other materials, including various metals or alloys, are also contemplated for use in forming the first and / or second sections. Both the first section and the second section are preferably formed through thermoforming, such as an injection molding process. It is understood that other methods may be used to form the first and second sections of the adjustable flush connector 11150, including resin casting, compression molding, or three-dimensional printing. It is also understood that each section can be made using a different process. The length l _FC of the adjustable flush connector 11150 as measured along the longitudinal centerline CL is preferably between about 60 mm to about 130 mm. The length l _1FC of the first section 11151 is preferably between about 10 mm and about 50 mm, and the length l _2FC of the second section 11152 is preferably between about 50 mm and about 100 mm.

  [0203] The first section 11151 preferably comprises the socket element 11166 of the ball / socket connector 11154, and the second section 11152 preferably comprises the ball element 11167 of the ball / socket connector 11154. Both the socket 11166 and the ball 11167 may have a general spherical shape. The ball element 11167 of the second section 11152 is preferably sized to fit within the socket element 11166 of the first section 11151 with minimal movement along the longitudinal axis with respect to the first section 11151. It is held so that The ball 11167 should be sized to move freely within the socket 11166. The outer surface of the ball may be in contact with the inner surface of the socket, but if contact is made, the friction created between the elements should be such that it does not interfere with the free rotation of ball 11167 in socket 11166. is there. However, it is also acceptable to use additional forces to cause the rotation of the elements with respect to each other by friction.

[0204] The second section 11152 of the adjustable flush connector 11150 has an outer surface 11155 that may have an optional thread 11159 to take a configuration that mates with the adjustable connector 11156. The preferred diameter D _2AC of the outer surface 11155, except for the threads of the second section 11152 is in the range of about 3mm to about 12 mm. The threads 11159 on the surface 11155 of the adjustable flush connector 11150 may extend along the entire length of the second section 11152 except for the balls 11167, or other connector elements. However, it is understood that only a portion of the surface 11155 may be threaded. If only a portion of surface 11155 has threads 11159, the threads should be at least about 20mm, but adjustable connector 11156 is sufficient to engage this surface 11155. In addition, it is understood that surface 11155 may not include threading.

Using threading to connect the adjustable connector 11156 to the second section 11152 is a preferred embodiment, however, other ways of connecting the adjustable connector 11156 to the second section 11152 It is also understood that can also be used. Such a connection includes a slidable connector with a fastening member, as well as an adjustable connector 11156, which can be moved longitudinally along the second section 11152 and the longitudinal direction of the second section 11152. Any other connection that allows it to be rotatably positionable about an axis may also be included. Second section 11152 may also be configured such that another adjustable connector 11156 is not required. Such second section 11152 may include one or more protrusions or one or more openings located along the length of the second section for direct connection with the flush actuation bar. Can be provided. The location of the flush actuation bar 1175 is determined by selecting a location for a direct connection using the protrusion or opening on the flush actuation bar 1175 with the opening or protrusion on the second section 11152. It would be adjustable along the length of section 11152. In addition, the angle of the openings and / or protrusions in the second section 11152 can be varied about a central longitudinal axis, so that the flush actuation bar also has a longitudinal section of the second section. It may be possible to position it rotatably about an axis.

  [0207] The adjustable connector 11156 preferably has a second rotatable connector 11157. The second rotatable connector 11157 is configured to connect the flush actuation bar 1175 to the adjustable connector 11156 at a balance point BP on the flush actuation bar 1175. The configuration of the second rotatable connector 11157 is such that the flush actuation bar 1175 is rotatable about a lateral straight line extending across the adjustable connector 11156 from side to side. Certain preferred configurations are discussed below. The balancing point BP is preferably such that when the flush actuation bar 1175 is lifted, the lift is typically depressed on the handle H or the end 11143 of the rotating rod P connected to the adjustable flush connector 11150. , But arranged such that the timing of opening each valve with respect to the other is optimized. One embodiment for optimizing the timing between opening and closing of the valve cover has been described above and is shown in FIG.

[0208] The flush actuation bar 1175 preferably has a bar body 11169 with a preferred length l _FB of the flush actuation bar 1175 between about 90 mm and about 130 mm. A preferred width w _FB of the flushing operation bar 1175 is between about 2 mm and about 5 mm, and a preferred height h _FB of the flushing operation bar 1175 is between about 5 mm and about 15 mm. The cross section of the flush actuation bar 1175 may be substantially rectangular. However, as will be appreciated by those skilled in the art based on the present disclosure, any shape cross section could be used, including circular, oval, hexagonal, triangular, and the like. Rinse actuation over 1175 may be made from a polymeric material, metal, or metal alloy, and is preferably injection molded using acetal. However, any method of manufacture including resin casting, compression molding, or three-dimensional printing may be used to make the flush actuation bar.

  [0209] The flush operation bar 1175 preferably has two side arms 11177. The two side arms 11177 form and define a large opening 11164 in the bar body 11169 that is preferably located around the counterbalance point BP of the flush actuation bar 1175. The large opening 11164 defined by the side arm 11177 may extend along the longitudinal axis of the flush actuation bar 1175. The large opening 11164 preferably has an oval cross section. However, any shape for the large opening 11164 is contemplated, including circular or rectangular. The side arms 11177 are preferably symmetric about the longitudinal axis of the flush actuation bar 1175, but symmetry of these elements is not required. For the preferred shape of the flush actuation bar 1175, the side arms 11177 should be parallel to each other at at least one location along its length. It is contemplated that the size for the large opening 11164 is such that at least a portion of the entire adjustable flush connector 11150, including the adjustable connector 11156, can be inserted therethrough.

  [0210] Where the two side arms 11177 are parallel to each other, two small openings 11165 are formed through the side arms 11177 that are formed as part of the flush actuation bar 1175 and define a larger opening 11164. Direction. The small opening 11165 is preferably circular, but may have any shape that allows rotation of the connecting element, and at least the bottom of the small opening 11165 should be substantially curved is there. The small opening 11165 is preferably configured to correspond to or receive two protrusions 11163 extending from the side of the adjustable connector 11156.

  [0211] The adjustable connectors 11156 each extend from one side of the adjustable connector 11156 to attach the flush actuation bar 1175 to the adjustable connector 11156 and form a second rotatable connector 11157. To be provided. The two protrusions 11163 are preferably positioned toward the top of the adjustable connector 11156, and are preferably co-linear with each other and extend across the adjustable connector 11156. The protrusion 11163 preferably has a cylindrical shape. However, any cross-sectional shape, such as an oval, is contemplated. The cross-sectional shape is preferably round, at least on the bottom edge, so that the protrusion 11163 can rotate within the small opening 11165 of the flush actuation bar 1175.

A rotatable connection is formed around the protrusion 11163 about the axis. The protrusions 11163 are preferably snapped into place using the springs and / or torsional compression of the protrusions 11163 and / or the side arms 11177 so that the protrusions 11163 fit within the small opening 11165 Is locked in place. The protrusion 11163 may be spring-loaded to penetrate into the small opening 11165, and the preferred end 11179 of the protrusion 11163 may facilitate insertion of the protrusion 11163 into the small opening 11165. It may be angled. If removal is desired, angled end 11179 can also assist in removing protrusion 11163 from small opening 11165. While a removable connection is preferred, the protrusion 11163 may have a shape and / or size that makes removal difficult or makes removal a highly impractical task.

  [0213] Any type of connection that is rotatable about the horizontal axis of the flush actuation bar 1175 is considered by those skilled in the art based on this disclosure to be an acceptable alternative to the second rotatable connector 11157. Understood. The use of an opening through the adjustable connector 11156, and the second section 11152 of the adjustable flush connector 11150 through which a pin can be inserted and passed, also allows the flush actuation bar 1175 to be moved to the adjustable flush connector 11150. It is contemplated to form a second rotatable connector 11157 for connection. In one such embodiment, two or more openings are required on the second section 11152. The openings extend across the second section and are positioned at various points along the length of the second section. Two or more of the openings may extend across the second section at one or more different angles with respect to each other. The two or more openings may allow the adjustable connector 11156 to be longitudinally movable and rotatably positionable. A similar arrangement may also be used to connect the flush actuation bar 1175 directly to the second section 11152 of the adjustable flush connector 11150 without using the adjustable connector 11156 as described above. Can be used. Other possible connections may include a threaded surface on the protrusion 11163. A mating threaded female piece with a smooth outer surface could also be used to removably secure the flush actuation bar to the adjustable connector and form a second rotatable connector. is there. Riveted connections that can form either removable or permanent connections can also be used.

  [0214] FIG. 69 includes a first valve assembly, a second valve assembly, a tool-less flush actuation bar and an adjustable flush connector connected to the rotating rod P and handle H. An embodiment of an assembly kit 1100 having a flush actuation assembly as shown is shown. Alternative kits include the following tank / bowl gasket tool, as shown in FIGS. 83 and 84 below, a float attachment as shown in FIGS. 88-90, or FIGS. 80-81. May also accommodate one or more of the multiple flush valve assemblies as shown in FIG. FIG. 69 shows the connection relating the action on the handle H to the opening of the valve. When handle H is depressed, rotating rod P vertically lifts adjustable flush connector 11150, which in turn moves flush actuation bar 1175 vertically at balancing point BP. The flush actuation bar 1175 is preferably connected to a first valve assembly 1180 at a first portion 11161 of the bar 1175 and a second valve assembly 1170 at a second portion 11162 of the bar 1175. . First valve assembly 1180 is preferably a rim valve assembly, and second valve assembly 1170 is preferably a squirt valve assembly. The rim valve assembly 1180 and the squirt valve assembly 1170 are described herein in various embodiments of the primed toilet and are similar to those described in the earlier embodiments as valves 80 and 70.

Similarly, hooks or other male fittings may be included in one or both of first portion 11161 and second portion 11162.

  [0215] The placement of the balance point BP between the adjustable connector 11156 and the flush actuation bar 1175 can affect when each valve cover 1182 and 1173 opens. The valve covers 1182 and 1173 can be set to open simultaneously, or the siphon priming as described with respect to FIG. 15 by allowing the rim valve cover 1182 to fully open before the squirt valve cover 1173 begins to open. It can be set to optimize performance on the toilet.

  [0216] When the flush cycle is activated, fluid is passed through at least one rim valve, here through rim flush valve assembly 1180, and at least one flush flush valve, flush flush valve assembly 1170 as shown here. Supplied through. The configuration of the closed squirt fluid passage is such, and the timing of the squirt cycle is optimized to keep the closed squirt fluid passage primed after the completion of the squirt cycle. The ejection mechanism and timing may be the same as the optimized performance described in the various embodiments 10, 110, 210, 310, 410, etc., and the examples included herein.

  [0217] In one embodiment of the method herein, after activating the squirt cycle, the flush actuation bar directs fluid through at least one squirt flush valve assembly to prevent air from entering the squirt outlet and to provide a trapway. Operate to supply at a flow rate sufficient to generate a siphon within. The flow rate is then reduced through the blast channel for about 1 to about 5 seconds until the siphon breaks, and the flow is maintained at least until the blast outlet port is covered.

  [0218] Fluid is also supplied through at least one rim ejection valve assembly, preferably in an ejection cycle. When first installed, the toilet bowl will have a sufficient flow through the squirt flush valve assembly outlet to prevent air from entering the squirt outlet port until the sump is filled with fluid as described above. By supplying, it may be necessary to prime first. The associated flow rates for performing these steps are outlined elsewhere herein. The toilet assembly can be primed as described above, and all or substantially all of the air will be expelled from the squirt channel when the stool is in a condition to force the squirt channel. Is preferred. For general performance, a small amount of air is closed, preferably including up to only about 100 ml of air in one embodiment, such as embodiment 10 shown herein, while maintaining good operation. Should be allowed into the fluid ejection path, but acceptable performance may include additional amounts of air, but preferably no more than about 500 ml of air to avoid performance degradation. . The particular amount may vary depending on the bowl geometry.

  [0219] The toilet bowl is typically, for example, when the toilet bowl is first installed as noted above, although other situations such as plumbing or maintenance may cause such a situation. Is in a primed state. The user may, of course, perform manual intervention to prime the toilet assembly after installation, or when configured, the toilet may be flushed out of the first few flushes of the toilet without user manual intervention. Automatic priming can be performed over one or more.

  [0220] As shown herein in FIGS. 1-13 and 29-34, a toilet bowl can displace virtually all of the air with as little as about three rinses, but with Depending on the toilet geometry, the number required may be more or less. In order for the autopriming to be completed, the following two conditions must be met: (1) the flow rate of fluid through the flush valve should be such that the fluid exiting the flush outlet port provides enough energy to displace the air. The condition must be met that it must be greater than the flow rate and (2) the air must be provided with a route to escape up from the outlet or through the flush valve assembly. This may be accomplished through modification of the geometry and / or cross-sectional area of the ejection channel and / or ejection port and / or by modifying the ejection valve to enhance performance. Therefore, it is preferred to use a flush flush valve that can direct high energy and high velocity flow through the flush channel into a closed flush fluid path. A preferred valve has a streamlined valve body configuration and is disclosed in U.S. Pat. 266,733 and co-pending U.S. Provisional Patent Application No. 2014/0090158.

  [0227] At least one squirt flush valve assembly 70 and at least one rim flush valve assembly 80 may each be a dual flush valve assembly. An example of a flush valve assembly known in the art that may be preferred in embodiments herein is found in U.S. Patent No. 8,266,733 B2, the relevant portions of which are incorporated herein by reference. Can be issued. The two valves may be opened and closed at the same time, or may be opened and closed at different times in the flush cycle to further optimize performance. It is desirable to open the rim flush valve before opening the squirt flush valve to clean the bowl with cleaner flush water. In a preferred embodiment of a 6.0 liter / 1 flush, the rim flush valve is opened immediately after the start of the flush cycle and closed about 0.1 to about 5 seconds into the cycle, while the squirt flush valve is The cycle opens in about 1 to about 5 seconds and closes in about 1.2 to about 10 seconds.

  [0228] In very low volume flush toilets, 3 liters / 1 flush, the rim flush valve is opened shortly after the flush cycle begins and closes about 1 to 3 seconds into the cycle while squirting. The flush valve opens in about 0.1 to about 3 seconds into the cycle and closes in about 1.2 to about 3 seconds. In the embodiments herein, using a 54 mm diameter trapway, only about 1 liter flowing from a fully primed closed blast channel is required to initiate a siphon, and the bowl wash Depending on the desired effectiveness of the water and the amount of water directed to its function, it allows the application of the present invention to flush toilets operating at volumes of 2 liters or less.

  [0229] Another embodiment of a double flush toilet assembly opens the double flush valve as a rim flush valve immediately after the flush cycle begins, thereby triggering the squirt flush valve (single or double flush).

Preferred height h _2VS for the second vertical section 11213 is between about 3mm to about 8 mm. However, this height h _2VS depends on the height h _1VS of the first vertical section and also on the height h _UP of the upward projection 11222 of the second link 11220. The greater the height h _UP of the upward projection 11222, the smaller the height h _2VS of the second vertical section 11213 must be. However, the amount of contact area between the second vertical section 11213 and the upward protrusion 11222 adjacent to each other may not be critical.

The height h _HE of the horizontal element 11223 is preferably sized such that the top 11224 of the horizontal element 11223 is directly below the bottom 11217 of the second vertical section 11213 of the first link 11210. The height h _HE of the horizontal element 11223 may vary from about 2 mm to about 27 mm, and the height h _UP of the upward projection 11222 is more important. The preferred height h _HE for the horizontal element 11223 is such that the first link 11210 and the second link 11220 keep the distance d _V between the valve assemblies 1180 and 1170 relative to each other relatively constant. Corresponds to the preferred size of the three sections 11212, 11213, 11214 of the link 11210.

The upward projection 11222 preferably has a size that fits within the hook shape formed by the first link 11210. The height h _UP of the upwardly protruding portion 11222 of the second link 11220 is such that the rim valve main body 1131 and the ejection valve main body 1121 are fixed to each other and cannot move toward each other or away from each other. May be high enough to work with the second vertical section 11213 of the first link 11210. The preferred height h _UP of the upward projection 11222 is from about 2 mm to about 5 mm, but the height h _HE of the horizontal element 11223 and the first vertical section 11212 and the second vertical section 11213 of the first link 11210 Height h _1VS and h _2VS . The preferred length l _UP of the upward projection 11222 is from about 1 mm to about 5 mm. This preferred length may be selected such that the upward projection 11222 fits snugly within the hook shape of the first link 11210, such that both the valve assemblies 1180 and 1170 are toward each other. Or movement away from each other is minimized.

  [0242] Although the second link 11220 is described as having two sections 11222 and 11223, the preferred second link 11220 is made from a single piece of material. In particular, the second link 11220 may be made from a material, either a metal or a polymer material, and is preferably a polymer material molded in the shape described for the preferred embodiment above.

In addition, the first link 11210 and the second link 11220 may be integrally formed and the link device 11200 may have only one component. The link device 11200 as a single piece may be attached by connecting elements, including straps that are looped and loosely wound around the assembly, and / or fastening devices for connecting to the sides of both valve assemblies. For example, a single rigid article may be affixed to both valve assemblies. Such an article should be able to keep the distance d _V between the two valve assemblies 1180 and 1170 substantially constant. It should also be noted that the valve bodies 1121 and 1131 may also be formed as a single unit, thereby eliminating the need for a link device 11200.

[0244] Preferably, both the first link 11210 and the second link 11220 are made from a rigid material. However, a flexible material could be used for one or both of the links. If the upward protrusion 11222 is made of a compressible material, its length l _UP is increased so that the upward protrusion 11222 can be compressed and fit within the hook shape of the first link 11210. It is good. If a flexible material is used for some or all of the elements described for preferred first link 11210 and preferred second link 11220, the thickness and / or amount of flexibility that can be used is , Should not allow the first valve assembly 1180 and the second valve assembly 1170 to move substantially with respect to each other.

[0245] Looking at the link device 11200 from the top as shown in FIG. 79, the width W _LD of the link device 11200 extending across the tank is visible. The width of the first link 11210 and the width of the second link 11220 are preferably equal and sized so that slight movement of one or both valve bodies 1121 and 1131 in a direction transverse to the tank does not disrupt interlock. You may have. The preferred width W _LD of the link device 11200 is from about 20 mm to about 40 mm. Preferably, the width of the first link 11210 and the width of the second link 11220 are equal, but the width of the first link 11210 and the width of the second link 11220 may be larger and the link device 11200 It should be able to maintain a constant distance between the valve assembly 1180 and 1170d _V.

  [0246] One possible method of mounting to the multiple valve assembly 11205 according to this embodiment is to mount one of the valve assemblies 1180 or 1170 in the tank, and then separately mount the second valve assembly 1180 or 1170. That is. Each valve assembly is preferably separately mounted and secured to the bottom of the tank using conventional tank / bowl mounting methods. In addition, the tank / bowl gasket kit may be used as described below. Each valve body 1121 and 1131 can be inserted through a separate hole in the bottom of the tank. After attaching the second valve assembly 1170, the first link 11210 and the second link 11220 are preferably engaged. By using this method, one valve assembly can be removed, repaired, or replaced without adjusting or removing the other valve assembly.

  [0247] Another embodiment of a multiple valve assembly 11205 that includes a link device 11200 may have a single multiple flush valve assembly 11206 as shown in FIGS. A single multiple flush valve assembly 11206 may include both a first valve assembly 1180 and a second valve assembly 1170 provided together as a single unit. A single multiple flush valve assembly 11206 may have a first link 11210 and a second link 11220, as described in the above embodiment, which is permanently affixed to each other. In addition, the first and second valve bodies may be molded as a single structure. The affixed link device 11200 is preferably permanently affixed to both the first valve assembly 1180 and the second valve assembly 1170 to form a single multiple flush valve assembly 11206. For a single multiple flush valve assembly 11206, the entire structure is permanently connected, but the link device 11200 may be a separate element, and may be a separate first valve body portion 1131 prior to installation in the toilet bowl. It is to be understood that it may be permanently connected to the second valve body portion 1121 to form a single multiple flush valve assembly 11206.

[0248] Preferably, to create a single multiple valve assembly 11206, the two valve bodies 1121 and 1131 and the connecting piece 11207 linking the two valve bodies are integrally formed with each other. The two valve bodies 1121 and 1131 can be as described in any of the embodiments disclosed herein, such as 10, 110, 210, 310, 410, 1010, 1110. Or a conventional valve body as known in the art. Connecting parts 11207, preferably of the same material, may be molded with valve body portions 1121 and 1131 such that the entire structure is a single part. The connecting piece may also be permanently connected to the valve bodies 1121 and 1131 after formation. The connecting piece 11207 is preferably of a size sufficient to maintain a constant distance between the valve bodies, depending on the material used. Preferably, connecting piece 11207 is made of a polymeric material such as ABS resin, has a height h _CP of about 2 mm to about 10 mm, a width W _CP of about 10 mm to about 30 mm, and a length l _CP of about 2 mm to about 12 mm. Having. The length l _CP depends on the distance between the valve openings in the tank. The connecting piece 11207 preferably has a rectangular cross-sectional shape when viewed across the tank. Any cross-sectional shape is contemplated, and the shape may be circular, oval, triangular, octagonal, and the like.

  [0249] Another embodiment includes a mounting method using a single multiple flush valve assembly 11206, wherein the first valve assembly 1180 and the second valve assembly 1170 are permanently connected to each other. . In addition, this mounting method can be used to mount two separate valve assemblies 1170 and 1180 when the link device 11200 is engaged before the valve is mounted in the tank. In an embodiment comprising a single multiple flush valve assembly 11206, both the second valve body 1121, which is associated with the first valve body 1131, is mounted in the tank at the same time, providing a conventional tank / bowl mounting method. Can be used to secure to the bottom of the tank. In addition, the tank / bowl gasket kit may be used as described below. Each valve body 1121 and 1131 can be inserted through a separate hole in the bottom of the tank. If not permanently connected, separate valve assemblies 1170 and 1180 may be mounted in a connected configuration. If so, it is contemplated that the individual valve assemblies 1180 and 1170 may be disconnected from one another and removed individually from the tank. However, individual removal is difficult or impossible with a single multiple flush valve assembly 11206, wherein the first valve assembly 1170 and the second valve assembly are permanently affixed to each other. Can be

  [0250] In one embodiment, such as the toilet bowl assembly 110, to separate the fluid flow introduced into the bowl assembly 110 from the at least one flush valve assembly and to deliver different amounts of fluid to the jet 120 and the rim 132 There are separate manifolds. This means that fluid enters the bowl through one toilet inlet, flows into a single open manifold, and then goes down in an uncontrolled or gravity controlled manner into the jet 120 and rim 132 Distinguished from traditional toilet bowl designs. In such prior art designs, the amount and nature of fluid flow to the rim or direct jet is difficult to control and typically favors jets over rims due to gravity and flow momentum. Meanwhile, by isolating the fluid flow to spout 120 and the fluid flow to rim 132, the fluid flow was controlled and the spout and rim received the desired flow rates. In addition, this allows to maintain a closed squirt fluid path 101 that includes a primed squirt channel 138 and, preferably, a primed squirt manifold 112.

  [0251] The optional squirt manifold 112 is preferably pre-formed in a porcelain or other manufacturing material of the toilet bowl, arranged in a stacked position, and / or juxtaposed with the rim manifold. The manifolds can be paralleled, but not at exactly the same level. The squirt manifold 112 may have a squirt manifold outlet opening 116 for delivering fluid to the squirt inlet port 118. Rim manifold 122 is adapted to receive various volumes of fluid, for example, from about 0.1 liter to about 5.5 liters, from rim flush valve assembly 180, preferably from about 0.5 liters to about 4.5 liters. Rim manifold inlet opening 124 configured in Rim manifold 122 also has a rim manifold outlet opening 126 for delivering fluid to rim inlet port 128. Fluid flow through spout 120 proceeds directly down spout channel 138, exits spout outlet port 142 and enters sump region 140 at a different time than water entering through rim channel 134 enters these sump regions. One of the streams may stop before the other stream, but through at least part of the flush cycle, the streams may preferably occur simultaneously. These flow rates are selected to maximize cleaning of the interior surface 137 of the toilet bowl 130 before draining the sump area 140.

  [0252] In another embodiment, the rim channel 134 may be directly powered by line pressure from a typical residential or commercial plumbing line. Opening and closing of the flow to the rim can be controlled electronically with a mechanical pilot valve similar to those currently used as toilet fill valves, or with solenoid valves.

  [0253] Although the bowls herein, such as bowls 30, 130, may have different configurations, most bowls are generally round or elongated oval when viewed transversely from the top of the bowl. Alternatively, it is preformed so as to have an elliptical shape. In the embodiment described and illustrated herein, bowl 30 has a generally elliptical shape. The bowl 130 has a rim 132 provided on its upper periphery and defining a rim channel 134. The rim channel includes an inlet port 128 (at the transition point between the manifold and the rim channel where the rim channel has a more uniform cross section) in fluid communication with the rim manifold outlet opening 126 and a bowl assembly 110. Has at least one rim outlet port 129, preferably a plurality of such outlets, in fluid communication with an interior region 136 of the rim. The bowl 130 is provided such that the squirt channel preferably runs along the outer surface 135 of the bowl 130 or within the bowl wall, and the squirt outlet port 142 is located in the lower portion 139 of the bowl 130. It further has an ejection part 120.

  [0254] In various embodiments herein, such as the toilet bowl 10, the jet 20 directs fluid to the sump area 40, then to the inlet to the trapway 44, and to the toilet outlet O, which can be connected to the sewage outlet. It defines at least one blast channel 38 having a blast outlet port 42 configured to dispense.

  [0255] In the embodiment of FIG. 16, a portion of the wash water is passed through the rim channel 134 and through an opening 129 positioned in the rim to provide a flow between the channel 134 and the interior region of the bowl 130. It provides a fluid connection, which sprays water over the entire surface of the bowl 30 and serves to flush the bowl in a flush cycle. Water flowing through the rim channel 134 may also be pressurized in some embodiments herein after exiting the rim exit port 129 or after exiting an external fluid source as described above. Can be done. Depending on the size of the outlet port, the geometry of the toilet bowl, and the flow rate, pressurization can cause a strong compressed flow of water, cleaning the bowl and contributing to siphon action. The remainder of the rinsing water from the separate squirt valve assembly 170 is directed to the squirt 120.

  [0256] The jets 20, 120 and at least one jet channel 38, 138 herein provide a more powerful high velocity stream of flush water to the trapway inlets 44, 144, thereby further increasing the toilet bowl. Can be designed with a large diameter trapway, but with minimal bends and constrictions that can affect operation, and the performance of removing large amounts of waste with non-jet and / or rim-jet bowls Care should be taken to improve

  [0257] The at least one squirt channel 38 extends into the interior of the toilet bowl assembly 10 and is designed to pass over the exterior surface of the toilet bowl 30, but generally in the interior region wall 36 of the bowl 30. It is also positioned to enter at least partially into the space defined in the toilet bowl assembly body 10 below or directly below. Multiple jet channels of different sizes may be used, for example, two symmetrical channels on either side of bowl 30 deliver a “double-fed” flow of fluid to jet 20.

[0258] The squirt outlet port 42 is configured to discharge fluid from the squirt channel 38 to a sump area 40 that is in fluid communication with the trapway 44. The jet outlet port 42 preferably has a length of about 1.0 cm to about 10 cm, preferably about 1 cm to about 6 cm, and most preferably about 1 cm to about 4 cm as measured longitudinally across the inner diameter of the jet channel 38. _{Has a} height H _jop in one embodiment herein, as shown in FIG. _Regardless of the height H _jop , the cross-sectional area of the outlet port is maintained at an area of about 2 cm ² to about 20 cm ² , more preferably about 4 cm ² to about 12 cm ² , and most preferably about 5 cm ² to 8 cm ^2. Should be. In one embodiment herein, the height H _jop of the outlet port 42 at the upper surface 54 or at the top point is preferably less than the upper surface 56 of the inlet 49 to the _trapway 44 as shown. Is also located at a low sealing depth x and measured longitudinally through the sump area 40. The sealing depth x is preferably from about 1 cm to about 15 cm, more preferably from about 2 cm to about 12 cm, and most preferably from about 3 cm to about 9 cm, with air passing through the outlet channel 42 and through the ejection channel 38. Work to prevent This distance avoids tears in the squirt channel 38 and reduces the priming condition of the squirt channel 38 of the toilet bowl assembly 10 by fluid from the squirt flush valve assembly 70 or other flush valves before and after the flush cycle is activated. To maintain, it should preferably be below the minimum level of fluid in the sump area 40.

  [0259] As described above, maintaining the primed squirt channel 38, ie, the closed squirt fluid path 1, greatly reduces turbulence and resistance to flow and reduces toilet performance. Improve and allow you to use less water to start the siphon. The air in the ejection channel 38 blocks the flow of the washing water and restricts the flow of the ejection portion 20. In addition, if not purged, air may be expelled through spout outlet port 42 and into trapway 44, delaying the trap siphon and affecting bowl 30 fluid and waste removal.

[0260] To improve the bowl cleaning capability in rim channel embodiments such as 110, it is also a preferred option to design the toilet assembly so that the rim is pressurized during the flush cycle. Pressurization of the rim channel 134 is preferably achieved by maintaining a relative cross-sectional area according to relation (I).
_{A rm> A rip> A rop} <6cm 2 (I)
Here, A _rm is the longitudinal cross-sectional area of the rim manifold 122, A _rip is the cross-sectional area of the rim inlet port 28, and A _rop is the total cross-sectional area of at least one rim outlet port 29. Preferably, the cross-sectional area A _jm of the ejection manifold 112 is from about 20 cm ² to about 65 cm ² , and the cross-sectional area A _rm of the rim manifold 122 is from about 12 cm ² to about 50 cm ² . The cross-sectional area A _jm of the squirt manifold 12 is measured at a distance of about 7.5 cm downstream from the center of the squirt flush valve inlet opening 162. Similarly, the cross-sectional area A _rm of the rim manifold 122 is measured at a distance of about 7.5 cm downstream from the center of the rim flush valve inlet opening 164. A gravity head obtained from a source or in a tank by maintaining the preferred geometry of the water channel within these parameters and avoiding constrictions or bends that otherwise affect performance A toilet bowl assembly 110 that maximizes the potential energy gained by the toilet bowl is enabled, which becomes crucial when a reduced amount of water is used in the flush cycle. In addition, by maintaining the water channel geometry within these parameters and avoiding constrictions and excessively small passages in the spouts or traps, the rims in direct-flush spout toilets And a preferred pressurization of the ejection channel to maximize performance in both bulk removal and bowl cleaning. Preferably, the area of the rim exit port is intended to be the sum of all the individual areas of each such exit port, as there are multiple rim exit ports that can vary in size depending on the desired design. You. Similarly, if multiple outlet channels 118 or multiple outlet / inlet ports are used, the outlet channel 118 or any of the multiple ports 142 will be the sum of the areas of the outlet channels or ports, respectively. In addition, to take advantage of the pressurization in the rim, the squirt channel is incorporated into the rim and squirt channel sizing in the pressurized rim siphon design and related parts with respect to the toilet geometry. As described in U.S. Patent No. 8,316,475, when working with a pressurized rim, it is preferably not made too small or constricted to avoid clogging and reduced performance.

  [0261] The sump area 40 of the toilet bowl 30 in embodiment 10 collects water from the rim, squirt channel 38, and flushes and drains flushing water and waste. The sump area 40 is located within the bottom portion 39 of the bowl 30 and extends longitudinally by the interior surface 36 of the bowl 30 and from the trap inlet end 46 to the trap outlet end 50 for the spout 20. , Wherein the inlet end 46 has an opening 48 for receiving fluid from the outlet port 42. Trap outlet end 50 has an opening 52 for fluid to exit the bowl and enter the trapway 44. The spout trap 41 has a seal depth x, ie, the top point on the upper surface 54 of the entrance to the trapway 44 and the spout outlet port 42, as shown in FIGS. Has a distance between it and the top point on the upper surface 54.

  [0262] The sealing depth x of the squirt trap is preferably from about 1 cm to about 15 cm, more preferably from 2 cm to about 12 cm, most preferably from 3 cm to assist in maintaining a siphon in the sump area 40. Measured to maintain a distance of about 9 cm. When the squirt trap sealing depth x is large enough, this can cause the trapway to be pulled before the water level in the squirt trap 41 can be pulled below the depth at which the seal of the squirt channel 38 is broken. Establish a level of relaxation of the fluid in the sump region 40 that helps ensure that the siphon breaks, thereby preventing air from traveling into the bleed channel 38 and allowing the bleed channel 38 to be fully primed To maintain. Conversely, in some embodiments, the flush trap sealing depth x can be equal to or less than 0 (when above the trap), and the flow rate through the flush flush valve assembly 70 Can still be primed in the squirt channel 38 and path 1.

[0263] Within the sump region 40, at least a portion of the interior surface 36 is sloped upwardly from the spout outlet port 42 toward the trap inlet, thereby increasing the sealing depth x of the spout channel 38 and flushing. It has a beveled portion 58 that reduces the likelihood of air entering the bleed channel 38 during a cycle or after a flush cycle. The sealing depth x may be further extended by forming a squirt channel 38 that temporarily sinks below the sump floor before rising to the spill port 42 at the sump floor. The sealing depth x can also be increased by reducing the diameter of the jet outlet port 42. Preferably, the height H _jop of the spout outlet port 42 may be reduced to form a circular, oval or rectangular outlet, which increases the sealing depth x of the spout channel 38. While maintaining sufficient cross-sectional area and flow through spout 20.

  [0264] FIG. 20 illustrates an alternative embodiment, referred to generally herein as assembly 1010, except for the features of tank 1060 with a separate reservoir as described below. , And in all other respects, similar reference numbers indicate similar elements therein. The tank 1060 may include at least one squirt reservoir 1068 and at least one rim reservoir 1072, wherein the squirt reservoir 1068 is configured to deliver a squirt fill valve 1090 and fluid to the squirt manifold inlet opening 1062. The rim reservoir 1072 may include at least one squirt flush valve assembly, which may be the same as in the assembly 10, such that the rim fill valve 1092 and the rim fill valve 1092 deliver fluid to the rim manifold inlet opening 1064. It may have at least one rim flush valve assembly configured, which may be the same as in assembly 110. This can be a partial transverse split of the tank 1060, which allows the use of one fill valve, or the tank split can be a permanent pre-formed casting of the tank into multiple reservoirs Things are fine. If an overflow tube is present in both the squirt reservoir 1068 and the rim reservoir 1072, as appropriate, the overflow tube must be operated from the rim flush fluid stream RF 'and not from the squirt flush fluid stream JF'.

  [0265] Figures 23 and 24 illustrate another embodiment, referred to herein generally as assembly 210. With respect to all other points, except that the inclined wall of the sump area is configured with an upward slope or a position tapered toward the entrance of the trapway 244 as described below. This is the same as the embodiment 110. The sump wall 258 as shown in FIGS. 23 and 24 extends around the sump area 240 and is designed to enclose the sump area 240. The squirt outlet port 242 provides a means for the fluid JF ″ from the squirt channel 238 to enter the bowl sump region 240, thereby entering the toilet bowl from the rim through at least one rim outlet port (not shown). It is positioned so as to join with. The jet fluid stream JF "and the rim fluid stream RF" merge at this point (with waste and other fluids, if any), and then along the bowl interior surface 236 and above the sump area, They generally flow together in a downward direction, enter the sump area 240, enter the trapway entrance 244, and are rejected through a sewage drain. At least a portion of the wall 258 is sloped upwards, if desired, to increase the sealing depth x of the ejection channel 238, wherein the sealing depth x is applied to the ejection channel 238 during or after the flush cycle. Help prevent entry. When the sealing depth x is large enough, this may cause the trapway 244 to break the siphon before the water level in the spout trap 241 can be pulled below the depth at which the seal of the spout channel 238 breaks. By helping to ensure that the relief level of fluid in sump area 240 is established, thereby preventing air from traveling into squirt channel 238, the squirt manifold 212 is fully primed. To maintain.

  [0266] FIGS. 25-27 illustrate an embodiment different from that of FIGS. 16-24, which is herein generally referred to as assembly 310. FIG. Same as embodiment 10 in all other respects except that at least one spout channel 338 is below the bowl sump region 340 as described below. The at least one squirt channel 338 is designed to extend into the interior of the toilet bowl assembly 310 to be located behind the sump region wall at the rear of the interior region wall 336 and the bowl 330, but the bowl 330 Is positioned to at least partially enter the space defined within the toilet bowl assembly body 310, generally below the interior region wall 336 and the sump region wall 358. At least one spout channel 338 that passes below or below the sump area 340 terminates in the sump area wall 358, thereby positioning the spout outlet port 342 directly opposite the entrance to the trapway 344. I do. The advantage of this structure is that the design is gravitationally capable of maintaining the capacity of the entire squirt fluid JF '' 'and that the level of fluid in the squirt channel is essentially reduced before the flush cycle is activated. At least one spout channel 338 remains more easily primed because it is below the fluid or flush water level in the bowl, both after and after actuation, thus eliminating air in the spout channel 338. It is. By locating the bleed channel 338 below the sump floor, the sealing depth x of the bleed channel 338 can be reduced to a tilted sump floor implementation as depicted in FIGS. Further increasing beyond what can be achieved by the configuration, the trapway breaks the siphon before the water level in the ejection trap 341 can be pulled below the sealing depth x at which the seal of the ejection channel 338 breaks. It provides greater assurance, thereby preventing air from traveling into the ejection channel 338 and keeping the ejection manifold 312 fully primed.

  [0267] FIG. 28 illustrates an embodiment different from that of FIGS. 16-27, referred to herein generally as assembly 410. Except for the features of the upper peripheral portion 433 on the upper circumference of the bowl 430 as described below, it is the same in all other respects. The rim 432 has an upper perimeter portion 433 positioned about the inside of the upper perimeter of the bowl 430 so that fluid RF '' '' from the rim manifold can direct waste into the sump area 440. It enters the bowl for flushing and enters the toilet bowl through spout channel 438 and merges with the displaced fluid through spout outlet port 420. The jet fluid flow JF "" and the rim fluid flow RF "" merge at this point (with waste and other fluids, if any), and then along the bowl interior surface 436, the sump wall Above 458, it generally flows together in a downward direction, enters sump area 440, enters trapway entrance 444, and is rejected through a sewage drain. When the sealing depth x is large enough, this can cause the trapway to break the siphon before the water level in the spout trap 441 can be pulled below the depth at which the seal of the spout channel 438 breaks. Helps to establish a relief level of fluid in the sump area 440, which helps to ensure airflow, thereby preventing air from traveling into the ejection channel 438 and keeping the ejection manifold fully primed I do.

  [0268] In another embodiment, a rimless version of the embodiment is depicted in FIG. 28, in which fluid flow flows from the rim inlet port in two opposite directions on the upper peripheral portion 433 to the rear of the distributor and the rim shelf. And about at least partially around the interior surface of the bowl, thereby forming a cleaning action. In a preferred embodiment, the upper peripheral portion 433 may be formed to guide the flushing water downward as it flows over the circumference of the bowl 430. This embodiment is similar to the assembly of FIGS. 1-13, but has a different rim shelf design.

  [0269] In one embodiment of the preferred method of the present invention, after being provided, such as by manufacturing a toilet bowl assembly 10 such as described herein, the squirt is activated before and after the flush cycle. It is subsequently primed with fluid JF from at least one gushing flush valve assembly 70. Although the methods herein may be practiced in any of the embodiments herein, including assemblies 10, 1010, 110, 210, and 310, 410, etc., for convenience, exemplary embodiments of the methods are illustrated in the figures. Reference is made to the assembly 10 embodied in FIGS. Similar parts in alternative embodiments may be used when practicing the invention with other embodiments.

  [0270] Priming the squirt manifold 12, the squirt inlet port 18, and the at least one squirt channel 38 prior to the operation of the rinsing cycle is performed when the squirt valve flushing assembly 70 is mounted to the toilet bowl assembly 10 on a mounting surface. By opening a flapper or cover and allowing fluid (such as rinsing water) to flow through the spout inlet port 18 and at least one spout channel 38. This priming operation is automatically performed by the first operation of the flush cycle. When the rim flush valve 80 and the flush flush valve 70 close, water is maintained in the flush channel 38 and the flush manifold 12 and is held in place by the force of atmospheric pressure on the surface of the water in the bowl 10. If any air pockets remain in at least one bleed channel 38 or bleed manifold 12 after the first flush, they will be extruded during a subsequent flush to form a fully primed system.

  [0271] After the first priming of the toilet bowl assembly of the embodiments herein, the user activates the flush cycle. In a standard prior art toilet bowl assembly, a flush valve assembly and overflow tubing, such as those described herein, are provided for use. The flush valve assembly and the flush valve cover connected to the valve are both connected to the pivot arm. A pivot arm is attached to the top of the flush valve cover and a link for attachment to a chain that can be used to lower and raise the valve cover by actuation of any standard valve actuator such as a flush handle and lever. including. In use, the pivot arm of the flush valve cover is attached to the overflow pipe using a standard connecting connection projecting from the overflow pipe and opens and closes over the inlet opening of the flush valve assembly.

  [0272] When a flush cycle is initiated or activated in the present invention, the flush valve cover opens both the rim flush valve assembly and the squirt flush valve assembly, and fluid causes at least one squirt flush valve assembly 70 to open. Allows you to pass through to the spout and rim. These may be opened simultaneously or through a time delay system as known in the art or later developed, thereby using the flush actuation bar 75 and 1175 embodiments noted above, and the like. Allows for optimal flow through the toilet bowl assembly 10.

  [0273] Following operation of the flush cycle, and after completion of the flush cycle, the outlet port 18 and at least one blow channel 38 may (1) reduce the depth of water in the reservoir supplying the flush valve by the flush flush. Do not lower to the level of the inlet 71 to the squirt flush valve 70 before the valve 70 is closed, and (2) the prime of the squirt channel 38 remains primed unless broken during or after the flush cycle. It is. If both of these conditions are met, the closed squirt fluid path 1, including the squirt channel 38 and the squirt manifold 12, remains fully primed and awaits the next flush cycle.

[0274] The present invention will now be described with reference to the following non-limiting examples.
An example
[0275] Table 1 summarizes data from 20 flushes completed using three different toilets. The present invention has been tested according to the embodiments shown herein in FIGS. 1-13 and 29-34. Conventional toilets that were tested required 79-82% of the wash water to be directed to the squirt to achieve the desired hydraulic performance of the siphon. Toilets made according to the present invention provide essentially equivalent hydraulic performance using less than 30% of the flush water directed to the spout, thereby significantly improving bowl cleaning using the remaining water. Made it possible.

  [0276] Each of the various embodiments 10, 110, 1010, 210, 310, 410, etc. herein can benefit from variations on the squirt flush valve of the present description. Optional and unique features may be added to the flush valve design noted above to improve operation of various embodiments. In use, if the toilet is clogged, or for some other reason, the toilet needs water plunge for various plumbing reasons, it not only releases the clog, but also climbs up the squirt passage and is constantly primed. It is important to prevent backflow through the spout valve in the closed state. Backflow is not a problem in conventional toilets because they are open to the atmosphere. In the primed invention, this is a problem due to the weight of the water and the existing water column in the spout channel. One method of modifying the flush valve of the present specification to withstand backflow is by providing a backflow prevention device on the flush valve. Such an apparatus will now be described with respect to a flush valve that is otherwise similar to the flush valve 70 herein.

  [0277] Although the flush valve design described above is very effective against possible water backflow during a water rush, in some embodiments, an additional level of protection is desired. Can be rare. By deliberately breaking the priming, i.e., letting air into a closed blast channel and opening it to the atmosphere, greatly reduces the possibility of backflow.

  [0278] FIGS. 35-38 illustrate one embodiment of a flush flush valve, referred to herein as a flush flush valve 570, having a flapper cover 573 and a backflow prevention mechanism 574 having a hold down link mechanism configuration. Show. Cover 573 may be the same as cover 15 of valve 70 in assembly 10. As shown, the cover 573 is mounted with a first front linkage mount 593 for mounting a hold down linkage. The linkage assembly within the anti-reflux mechanism 574 includes a first front linkage having an attachment point P for connecting the chain C (such as FIG. 15) to the actuator mechanism to allow the cover 573 to be lifted. An arm 575 is included. Such a chain may be provided with a float as described above.

  [0279] The first linkage arm is connected to the second linkage arm 576 by a hinge pin, such as a pin 578, but other hinge connectors, pins, living hinges, molded pins, rivets, or similar mechanisms. May be used. Similarly, linkage arm 576 is connected by a similar hinge connector to a third linkage arm 577 that is also pivotally mounted to rear hinge mount 579. In use, when the flapper is lifted, the hold-down linkage of the backflow arrestor lifts up and bends freely as shown, thereby causing the link between the first and second linkage arms when fully opened. Form an angle of less than about 180 °.

  [0280] When closed, the anti-reflux device moves the first and second linkage arms at the junction region R in a more rigid position that would remain if there was no action on the chain C at point P. Positioning the linkage arms so that they are more aligned prevents flow from pushing back onto the flapper cover 573 (FIGS. 37 and 38, showing the valve in the closed position).

  [0281] Another embodiment 670 of a squirt flush valve wherein the backflow prevention mechanism 674 is a movable buoyant poppet hat 694. FIGS. 39-43 show valve 670 in the closed position, wherein poppet hat 694 is pressed to seal in the area of outlet 613 of valve 670. The upward weight of the flush water on the closed valve prevents water from entering the interior of the valve. Backflow cannot enter the bottom of the squirt flush valve when the valve is closed due to pressure from within the closed squirt path primed with a poppet hat as described above. If a solid poppet hat (not as buoyancy) is used, greater force is required for operation and a spring or other pulling mechanism may be used to connect the hat to the guide.

  [0282] As shown in FIGS. 45-48, the squirt flush valve 670, when opened, is lifted by the cover 673 (a chain or other flush operation as described above with respect to the valve 70). Allows all flow (by devices etc.) through the valve body. When the cover 673 is lifted, the flushing water enters the pre-primed valve and a continuous downward flow pushes the poppet hat 694. Poppet hat 694 is preferably partially elastomeric or polymer to sealingly engage the valve at outlet 613. The poppet hat 694 is on a post 695 (which may be ribbed in cross-sectional design (or simply a circular post), as best shown in FIG. 45).

  [0283] The pillar has an upper end 699 configured to have a flange 6100 on a side opposite to where it connects to the poppet hat 694. The flange serves as a stop for the centrally located poppet post guide ring 699 in the valve body, below the ribbed structurally supported configuration. As best shown in FIG. 45, a "star" configuration of ribs 696 extending outwardly from central hub 697 is shown. An opening 698 extends through the hub and allows the poppet post to easily pass upward when the valve is in the closed position (see FIG. 43). When open, the column will move downward under flow pressure until the flange 6100 contacts the guide ring 699 in the fully extended position, so that the poppet hat 694 does not unnecessarily obstruct flow. .

  [0284] A further embodiment of a non-returnable spout flush valve 770 is shown in Figs. In this embodiment, the backflow prevention mechanism 774 is a hook 7101. The hook 7101 fits over the front end of the cover 7102 of the flush valve 770, which is different from other covers in other embodiments, as described below. The hook 7101 has an extension hook arm 7103 that contacts a catch 7104 positioned outside the ejection valve body. The hook arm 7103 must have some gap g between it and the opposing surface 7105 of the catch 7104, but this gap must be as small as possible to close tightly without backflow. However, the hook cannot easily pass through when the valve is opened and must not be small enough to rotate around the catch 7104, and preferably the gap is from about 1 mm to about 5 mm.

  [0285] A unique feature of the flush valve 770 other than the backflow prevention mechanism 774 is the cover 7102. The cover is not a simple lift-up flapper cover, but a "peel-off" cover. This design allows the bleed valve to open from the front of the cover along the edge toward the rear of the cover. The structure is formed to be flexible or partially flexible. Elastomers or other flexible polymers (such as flexible silicone or polyvinyl chloride) or other similar materials accepted for tubing and having tubing ratings may be adapted to the flexible portion. Peeling allows the valve cover to be more slowly peeled upwards along the edge 7105 of the front 7106 of the valve cover 7102 and toward the neck 7107 when the water is present above and below the cover. Helps reduce operating force. Applicants have realized that the use of a flexible or semi-flexible cover, which can be peeled off along the rim, provides a good self-priming aspect for the spout flush valve and closed spout path. I found it useful to do. With a rigid flapper cover, such as a hard cover with a standard disc-shaped seal, automatic priming can be more difficult. By peeling and opening slowly, valve 770 can allow all of the trapped air to escape. Preferably, at least about 50% of the cover 7102 is flexible at the front 7106 of the cover, half back towards the rear 7107 of the cover. The rear half of the cover need not be flexible.

  [0286] In order to activate the peeling mechanism and lift the hook backflow prevention mechanism, the first chain C1 was operated together with the flushing operation mechanism of the toilet when the valve was opened, and lifted the hook 7101 and lifted. Thereafter, the front portion 7106 of the cover is peeled off and lifted upward. When this is lifted, hinged arm 7108 (which may be formed using any suitable hinge / hinge connection material and structure as noted above with respect to embodiment 570) is bent upward. The hinged arm 7108 is attached to an optional cover plate 7110 (which may be metal, polymer, or elastomer) using a hinge mount 7109 to help peel the front 7106 of the cover 7102 upward. Suitable flush actuators may also be used and / or modified to connect to chains C1, C2. After C1 has lifted the front of the cover upward and peeled off at end 7105, the rear of the cover is lifted. There is a separate float attachment, which can be a second chain C2, which can have a float as described above. Other variations of the float attachment for connecting the float to the rear portion of the cover may also be used, which will be described in more detail below and include a float assembly as shown in FIGS. Including. Strings, cords, ropes, stainless cables, rigid rods, or wires may also be used with the float as an alternative embodiment of the float attachment.

  [0287] The interior of the valve 770 also preferably has a "star" configuration using a configuration formed from ribs 796 linking the body of the valve to a central hub 797 through which the opening 798 extends. The flow can easily pass through the rib structure, which aids in supporting the weight of the flushing fluid on the valve by extending radially across the body of the valve. The flapper has twice the force required to open, so the support assists in operation and is further designed to facilitate air escape using baffles or ribs shaped as shown. It is. The number of ribs can affect the flow if the ribs are too large or too large or shaped in an inconvenient manner.

  [0288] FIGS. 64-68 are the same embodiment of the valve 770, but with an optional overflow tube 791 incorporated thereon. The overflow tube 791 includes an upper housing 769 that can allow air to escape, to incorporate any of a variety of standard valves V therein as another check valve against backflow through the bleed valve. . The valve can be manually turned to the open position to break the priming and allow water to enter without backflow. Breaking priming may also be desirable in other situations, such as before maintenance work or repair. Suitable valves, such as ball valves, disc valves, or the like, may also be incorporated therein. Valve V is shown schematically in the partial cross-sectional view of FIG. Housing 769 is optional and other direct connection valves may be used. The valve may then be manually reset to a working position by the user and the toilet bowl may be returned to the primed state. Preferably, the valve may incorporate a non-return valve, which automatically opens when a positive pressure above that encountered during a normal flush cycle occurs in the closed squirt channel. Stays open, allowing air to enter the channel and break priming. The check valve can then be manually reset to a working position by the user and the toilet bowl can be returned to the primed state. Most preferably, the check valve returns to the closed position with a delay of about 5 to about 60 seconds without requiring manual intervention on the part of the user. This can be done, for example, electromechanically or mechanically by a flapper type valve with a liquid damping hinge.

  [0289] FIGS. 58 and 59 show an embodiment 870 that is identical to that of the squirt flush valve 770, having the same reference numbers therein indicating the same parts, but with the flush valve 870 having a star configuration of the support structure. , Except that it has eight ribs instead of the four shown in valve 770. The number and variations of such ribs have been modified to provide variable angles of the structural support without unnecessarily obstructing flow through the valve, and have been modified to maximize and smooth out air. It will be appreciated by those skilled in the art.

  [0290] FIGS. 60-63 show an embodiment of a flush valve 970 having a backflow prevention mechanism 974 with a hold down link mechanism configuration similar to that of the valve 570, but with a single downward direction. Instead of the third link mechanism arm of the third embodiment, a bridge type structure 9111 whose width increases as it extends downward is included. Bridged structure 9111 acts as a third linkage arm, but divides down resistance towards hinged arm 9108. Such a hinged arm 9108 is mounted at a hinge mount 9109 and operates to give the cover 9102 the ability to "peel" upward as in embodiments 770 and 870. The front portion of the anti-reflux mechanism 974 includes first and second hinged linkage arms 975, 976 similar to that of embodiment 570. The second linkage arm is linked to the top of the bridged structure 9111 by a standard hinge connection, which in turn engages the rear of the hinged arm 9108 by the hinged structure 9112. The first link mechanism arm is connected to the front 9106 of the cover 9102 by a hinge mount 993. A chain (not shown) may be attached to point P and lift the front of cover 9102 as described in embodiment 570, but unlike embodiment 570, cover 9102 may be As flexible as the cover 7102, and thus can be peeled upward. Still additional chains are used to hold the float in embodiment 710 and raise the rear half of cover 9102 at the location of grommet 9113 or similar structure as shown for chain C2 in embodiment 710. Can be done. Grommets 9113, or similar structures, may also be used to secure float attachments, including float assemblies, cords, cords, ropes, stainless steel cables, rigid rods, or wires as shown in FIGS. Can be used.

  [0291] FIGS. 69 and 70 illustrate another embodiment of a squirt valve assembly 1170 that is similar to embodiments 770, 870, and 970 of the squirt valve assembly. This embodiment may be used without a backflow prevention mechanism or may include a backflow prevention mechanism as shown in any of the above-described embodiments 570, 670, 770, 870, 970, and the like. As represented in embodiment 770, a solution to overcome the additional force needed to open the primed bleed valve is to provide a valve that gradually opens, where the section of the valve is "peeled-off". "Take away" and open to allow some water to enter the spout, thereby equalizing the pressure before the valve fully opens. The one or more valve assemblies, preferably at least the squirt valve assembly 1170, has a valve cover 1173 and a valve body 1121 and is configured to "peel" open. It is also understood that multiple valve assemblies in a single tank, including rim valve assemblies, may have similar configurations. Also, while the valve assembly is described herein for use with a siphon toilet, it is also understood that the valve assembly may be used with flush toilets, including flush toilets.

  [0292] FIGS. 73-75 illustrate one such embodiment of a valve cover 1173 that is similar to the cover 7102 of the embodiment 770 and preferably has a seal 11170 and a rigid cover 11180. The hard cover 11180 can preferably bend with the seal 11170 to gradually open the valve cover 1173. The rigid cover 11180 may have a peel section 11182 and a lifting section 11183, preferably separated transversely from each other. The peel section 11182 has at least one hinged mount 11108 that is preferably configured to connect with the lifting section 11183. The configuration of the connection between the hinged mount 11108 and the lifting section 11183 is preferably a rotatable connection. Such a configuration for a rotatable connection is described in further detail below and is shown in FIGS. 73 and 74.

[0293] The hard cover 11180 may operate similarly to the cover plate 7110 of the embodiment 770 described above. Preferably, the trailing edge 11185 of the stripping section 11182 and the leading edge 11186 of the lifting section 11183 are substantially parallel to each other and relative to a central longitudinal plane defined by VP and VP 'of the valve cover 1173. Substantially vertical. There may be a transverse separation TS between the edges 11185 and 11186. The distance d _TS from the trailing edge 11185 of the stripping section 11182 to the leading edge 11186 of the lifting section 11183 is preferably between 10 mm and 20 mm, although this distance may depend on the size of the valve cover 1173. Any separation distance d _TS , and even if there is no separation, is contemplated as long as the stripping section 11182 can be lifted from the valve body 1121 by a certain distance without the lifting section 11183 moving, and each section is included in the process. There is sufficient clearance to bend the seal 11170 without interference.

  [0294] A chain C1 may be used to connect the release section 11182 of the hard cover 11180 to the flush actuation bar 1175. When the flushing operation bar 1175 is lifted, the peeling section 11182 of the valve cover 1173 can be lifted from the valve body 1121. Peel section 11182 may be associated with lift section 11183 through hinged arm 11108. The hinged arm 11108 is preferably immovable at its connection with the stripping section 11182 and is configured to connect to the lifting section 11183 at a rotatable connection. The hinged arm 11108 may be integrally formed with the release section 11182 in a molding process, and may preferably have two pegs 11115 extending from the outside of each of the hinged arms 11108. The peg 11115 is preferably cylindrical and sized to be inserted into the slot 11116 on the hinged mount 11109. Although two hinged arms 11108 are preferred and shown in the figures, it is understood that one or more hinged arms 11108 may be used. An elastically deformable support member 11117 may be located between the preferred two hinged arms 11108. The elastically deformable support member 11117 is not required because the hinged arm 11108 can have a size and shape that is itself elastically deformable.

  [0295] The hinged arm 11108 preferably connects to the lifting section 11183 through a hinged mount 11109, and the connection is rotatable about a straight line parallel to the leading edge 11186 of the lifting section 11183. The hinged mounts 11109 each have a longitudinally extending slot 11116, preferably having an oval shape, but it is understood that any shape is possible, such as rectangular, circular, or hexagonal. . The peg 11115 on the hinged arm 11108 can be inserted into the slot 11116 by using an elastic deformation of the elastically deformable support member 11117. The oval shape allows the pegs 11115 to move not only rotatably but also longitudinally into the respective slots 11116. This movement allows the stripping section 11182 to interact optimally with the lifting section 11183. It is understood that any rotatable connection can be used to connect hinged arm 11108 to lifting section 11183, and that no longitudinal movement is required. Possible rotatable connectors are hinged-type joints, such as protrusions on one element that snap into the openings in the other element, or pins inserted into openings located in each element. May be used. Other types of connections that can rotate about the same axis are also contemplated, including ball / socket type joints.

  [0296] As peeling section 11182 continues to lift, hinged arm 11108 preferably rotates about its connection with hinged mount 11109, allowing peeling section 11182 to move for a short period of time without moving lifting section 11183. It allows lifting from the valve body 1121. After the peeling section 11182 has been lifted to a sufficient angle by the chain C1 and the flush actuation bar 1175, the hinged mount 11109 preferably acts on the lifting section 11183, causing the lifting section 11183 of the rigid cover 11180 to open, The entire valve cover 1173 is completely lifted from the valve body 1121. Float F may also be attached to valve cover 1173 using chain C2, float assembly 11270, described below, or other connecting device. The float can provide buoyancy to reduce the force required to open the valve cover 1173 and / or control the time that the valve closes through a drop in the tank level when flushing. The lower the position of the float along the chain, the longer the valve may close and the more flushing may occur.

[0297] An assembly kit 1100 having a first valve assembly, a second valve assembly, and a flush actuation assembly, without additional tools, wherein the second valve assembly has a float attachment in the form of a float assembly 11270. Is shown in FIG. Float assembly 11270 includes float F and float connector 11280 configured to connect the float to second valve assembly 1170. A float attachment according to this variant can be used instead of the chain C2 to connect the float to the second valve assembly. 89-90 show enlarged views of the second valve assembly 1170 with the float assembly 11270. FIG. 89 shows the valve cover 1173 in the closed position, and FIG. 90 shows the valve cover 1173 in the open position. Float connector 11280 may be a rigid or semi-rigid structure, which is preferably made from a polymeric material. However, the float connector may be made from a material having a suitable density that does not interfere with the operation of the float F when applying buoyancy to the valve cover 1173. The length l _FA of the float connector can be varied to adjust the speed at which the valve cover opens completely. The length l _FA may be in a range from about 4 cm to about 14 cm.

  [0298] The float connector 11280 has a first end 11271 and a second end 11272. The float F is fixed on the first end 11271 of the float connector 11280. The second end 11272 of the float connector is secured to the second valve assembly 1170 by using a clip 11273 that snaps over a raised bar 11274 located on a lifting section 11183 of the second valve assembly 1170. It is hingedly connected to the lifting section 11183 of the valve assembly 1170. Clip 11273 allows float assembly 11270 to rotate about the longitudinal axis of raised bar 11274. The longitudinal axis of the bar should be parallel to the axis about which the valve hinge 11275 rotates. The rotating connection, such as a pin, ball joint, or other known rotating or hinged connection, inserted through a hole in one or both elements, the rotating connection is a valve hinge 11275 It will be appreciated that the float assembly can be used to connect the float assembly to a lifting section of the valve assembly so as to be rotatable about an axis parallel to the axis of rotation of the valve assembly.

[0299] The first end 11271 of the float connector may include a clasp 11276 for retaining the float F. The clasp 11276 is somewhat resiliently deformable so that the force that attempts to return the clasp to a rest position when the float is inserted into the opening holds the float F firmly in place by friction. When used with a standard float, the opening of the clasp at its minimum height, h _SC , is preferably about 0 cm to about 4 cm high in the rest position, about 4 cm when the float is inserted therein. The height is 1 cm to about 5 cm (the height of the float). The height h _TC of the highest height of the opening of the clasp is from about 2 cm to about 6 cm both at rest and when the float is inserted therein. The bottom of the clasp may have a flat platform 11277 of similar shape when the bottom of the float and the top 11278 of the clasp can be curved so that the entire first end 11271 has a shape similar to a cotter pin. Take. The elastically deformable nature of the clasp allows the use of a variety of different floats so that the buoyancy of the valve cover is adjustable, and allows for easy float replacement if necessary. .

  [0300] After the peeling section has been lifted to the point where the upward force increases on the lifting section, the float helps to require less force to fully open the lifting section. When the valve opens, the connection between the second end 11272 of the float assembly 11270 and the lifting section 11183 allows the float F to stay in a vertical position through the opening in the valve cover. One or more stoppers 11279 may be located on either side of the clip 11273 so that when the water level falls below the level of the float F, the float assembly 11270 does not drop completely with the water level. Although a stopper is not necessary for the float to function properly, it will be understood by those skilled in the art based on the present disclosure that the float assembly may prevent interference with the operation of other parts of the valve assembly. Would.

  [0301] Although the second or ejection valve assembly is described as having a float attachment, the ejection valve assembly and / or the rim valve assembly may contain the float attachment, and either or both. May perform a similar operation.

  [0302] FIGS. 76 and 77 show a seal 11170 that may be used with a hard cover to prevent liquid from entering the spout when undesired and may move with the hard cover 11180 to gradually open the valve cover 1173. 1 illustrates one embodiment. The seal 11170 may have a sealing surface 11171 and a locking surface 11172. The locking surface 11172 can include a plurality of locking lugs 11173 that can help secure the seal 11170 to the hard cover 11180, as shown in FIGS. Seal 11170 is preferably positioned such that peel section 11182 and lifting section 11183 engage in opposition. The seal is preferably attached to the hard cover 11180 using only a plurality of locking lugs 11173 or in conjunction with an adhesive or other fastening method. Locking lug 11173 may serve as an additional feature to help prevent liquid flow forces from peeling seal 11170 from the rigid cover. While the use of locking lugs 11173 may be preferred, it is understood that adhesives or other fastening methods may be used alone.

  [0303] The locking lugs 11173 may help in the manner of release of the valve cover 1173. The arrangement of the locking lugs 11173 on the seal 11170 may be such that one or more locking lugs 11173 are disposed within the peel section 11182 and one or more engaging lugs, as described in more detail below. A stop lug 11173 may be allowed to be positioned within the lifting section 11183. As the peel section 11182 is lifted, a force may be applied to the seal 1170 in a direction opposite to the movement, which pulls the seal 11170 away from the rigid cover 11180 and closes the valve for a longer time than desired. May allow to leave. The delay can affect the timing between the opening of the rim valve and the opening of the squirt valve and / or can reduce the benefit of the peeling section opening before the lifting section. The locking lug 11173 preferably lifts from the valve body 1121 and applies an opposing force to the liquid on the seal 11170, which should be sufficient to maintain the proper timing for opening the valve.

  [0304] A plurality of locking lugs 11173 may be disposed about the locking surface 11172 and may be positioned to engage with a plurality of corresponding openings 11188 in the rigid cover 11180. A preferred arrangement may for example comprise three rows of locking lugs 11173, one or more locking lugs 11173 arranged in each row. Preferably, the first row 11174 may have at least one locking lug 11173 configured to connect to the peel section 11182, and the second row 11175 connects to the front of the lifting section 11183. May have at least one locking lug 11173, the third row 11176 having at least one locking lug 11173 configured to connect to the rear of the lifting section 11183. It is good. The configuration of the connecting portions of the lugs 11173 is such that the size and shape of each lug 11173 makes it relatively easy to insert the lugs into the openings, but makes it more difficult to remove the lugs from the openings. . The configuration of the connection between the locking lugs and the respective stripping and lifting sections may depend on the particular locking lug placement and shape. Preferred specific features of the arrangement are described in more detail below.

[0305] The particular arrangement of each locking lug depends on the size and / or shape of the valve cover 1173. Rows 11174-11176 may be located at various distances from a point CP located on the leading edge of seal 11170 on central vertical longitudinal planes VP and VP 'through valve cover 1173. Preferably, for standard valve cover sizes, the first row 11174 may be located at a distance d _1R from about 5 mm to about 15 mm from point CP, and the second row 11175 may be The third row 11176 may be located at a distance d _3R from about 40 mm to about 80 mm from the point CP, and may be located at a distance d _2R from about 40 mm to about 60 mm from the CP. This configuration should allow the seal 11170 to be fully secured to the rigid cover 11180, and should allow the peel section 11182 and the lifting section 11183 to open at different times.

  [0306] Other configurations for the plurality of locking lugs 11173 are also contemplated. For example, only a single row of locking lugs may be used, where the row is preferably located about 5 mm to about 30 mm from point CP. Such an arrangement allows the lugs to secure the seal to the rigid cover when the peel section is raised. A single row may also be located about 30 mm to about 90 mm from point CP. It will also be appreciated that two rows of locking lugs are used, wherein one row is located about 5 mm to about 30 mm from point CP and the second row is about 35 mm to about 90 mm from point CP. Where it is located. Generally, using no rows, using one or more rows, located between about 5 mm and about 30 mm from point CP, can be any combination of about 35 mm to about 90 mm from point CP. However, it is understood that no rows are used, including the use of one or more rows, as well as the use of no rows of lugs. The placement of the lugs may also depend on the size and / or shape of the valve cover 1173. Preferably, at least one row is located in peel section 11182 and at least one row is located in lifting section 11183.

  [0307] A preferred shape for each of the locking lugs 11173 may include a head 11190 and a neck 11191. The head 11190 is preferably slightly larger than the neck 11191 so that when the head 11190 is inserted into the corresponding opening 11188 in the hard cover 11180, the seal 11170 is adjacent to the hard cover 11180. It is locked in the position where it does. The head 11190 is preferably generally conical with a rounded top surface and the neck 11191 preferably has a generally cylindrical shape. The shape of the locking lug 11173 has been described as having a generally circular cross-section cut parallel to the seal based on the preferred shape described above, but with a head 11190 and / or neck 11191. It is understood that this cross-section of the can have any shape, such as oval, triangular, square, etc. Other shapes having a circular cross section, such as a spherical head, are also understood.

[0308] The distance d _TH measured along the traverse line on the cross section of the bottom surface 11192 of the head portion 11190 is greater than the distance d _TN measured along the traverse line on the cross section of the top surface 11193 of the neck portion 11191. May also be large. In addition, the perimeter of the bottom surface 11192 of the head 11190 is preferably greater than the perimeter of the corresponding opening 11188 in the hard cover 11180 such that the head 11190 performs a locking function with respect to the hard cover 11180. The circumference of the top surface 11193 of the neck 11191 is preferably smaller than the circumference of the opening 11188 in the hard cover 11180 to fit within the opening 11188. The neck 11191 may also be made from a compressible material that deforms when inserted into the opening 11188. In such a case, the circumference of the top surface 11193 of the neck 11191 may be larger than the circumference of the opening 11188 in the hard cover 11180. In addition, if a compressible material is used for the entire neck portion or locking lug, the head and neck portions may be unitary since the neck section deforms and provides sufficient locking when inserted into the opening. It is also possible that it could be shaped to take a cylindrical or other shape with a uniform cross section.

  [0309] The preferred shape for the locking lugs 11173 in the first row 11174 and the second row 11175 is a generally flat surface along the side of the valve cover 1173 that faces the central vertical longitudinal plane VP-VP '. 11194. The flat surface 11194 may extend along both the head 11190 and the neck 11191. The flat surface 11194 on the locking lug 11173 is optional and may be used to aid in mounting, but is not an essential element of the seal 11170.

  [0310] The dimensions of each head 11190 and neck 11191 of lugs 11173 may be uniform, but one or more lugs 11173 may have one or more uniform dimensions. As shown in FIGS. 76 and 77, one or more of the lugs 11173 may have a larger head 11190 and / or a larger neck 11191 than the other locking lugs 11173. Preferably, the locking lugs 11173 located in the third row 11176 are larger than the other locking lugs 11173 and have a different shape than the other locking lugs 11173. For example, in FIGS. 76 and 77, this locking lug does not share the flat surface 11194 with other locking lugs 11173. The different sizes and shapes of the locking lugs in the third row provide a more secure connection between the seal 11170 and the hard cover 11180 due to the large size and continuous contact with the top of the opening. Can be formed. One or more locking lugs 11173 may have different shapes, and all of the locking lugs 11173 may have uniform dimensions and / or shapes.

  [0311] The method of locking the seal 11170 to the hard cover 11180 preferably includes passing each locking lug 11173 through a corresponding opening 11188 of the hard cover 11180 and inserting therein. The head portion 11190 should elastically compress as it is inserted through the opening 11188, thereby expanding and performing a locking function after passing through the opening 11188. All locking lugs 11173 may be inserted into respective openings 11188 at the same time, or one or more may be inserted into respective openings 11188 at one time. Adhesive may optionally be applied to the locking surface 11172 of the seal 11170 and / or the adjacent surface of the hard cover 11180 before inserting the locking lugs 11173 into the respective openings 11188. When the seal 11170 is locked to the hard cover 11180, the head 11190 of the locking lug 11173 may be located on the opposite side of the hard cover 11180 from the locking surface 11172 and the neck 11191 may be It may be located within the opening 11188 and the locking surface 11172 may be aligned with and connected to the head 11191. It is not necessary to use a locking lug 11173 with a head 11190 and a neck 11191, as shown in the view for embodiment 770, and the lugs 11173 may have a corresponding opening in the hard cover 11180 for alignment purposes. It may have only a neck portion 11191 for insertion into the portion 11188. It is also contemplated to use a seal 11170 that is attached to the hard cover 11180 using only adhesive without locking lugs.
