Abstract
A toilet flushing system comprising a cylindrical receiver into which flush water is received through a fill valve; a float operating within a float chamber that is fluidly connected to said cylindrical receiver to open and close said fill valve according to the water level in said cylindrical receiver; and a displacer rotatably attached to an axis inside said cylindrical receiver to displace any required fraction of water from said cylindrical receiver into a bowl relative to the angle of rotation.
Description
- The present invention relates to toilet or urinal flushing systems.
- Today's most commonly used toilet flushing systems have the following short comings that need to be solved:
-
- Toilets are prone to leak.
- Small water leaks from the tank into the bowl or urinal goes unidentified unless close attention is paid.
- No visible or audible alerts when water from the flush tank leaks into the bowl;
- Identified water leaks often get ignored due to apathy or financial restraints of the user resulting in water wastage;
- Only two choices exist regarding the quantity of flush water dispensed into the bowl, half or full;
- Due to government mandated water restrictions reduced water usage per flush the efficiency of flushing is diminished;
- Condensation (sweating) occurs on the toilet tank due to the temperature difference between the tank and the surrounding whereby the condensate drains onto the floor resulting in water damage;
- It is generally expensive to replace failed components due to the cost of components and or the cost of professional labor.
- Flush handle is subject to contamination when activated by unclean fingers.
- This invention is based on the “Failure Mode and Effects Analysis” abbreviated as FMEA, a tool used in the design and manufacturing industry. According to this the components of a commonly used toilet flushing system are analyzed. The toilet flushing system commonly used today consists of a reservoir, a flush valve operated by a lever and a water fill valve controlled by a float.
- Failure mode and effects analysis is performed on the components the failure of which result in water wastage.
- Flush valve: A valve that is normally located at the bottom of the tank with a flapper and seat. Due to deterioration of materials or physical deformation or entrapment of foreign object between the sealing surface, flapper valves leak.
- Water fill valve: leak due to deterioration of seal or engagement.
- In this invention a backup valve located upstream of the fill valve closes the water supply in case the fill valve continues to allow water passage after being fully closed.
- Float: It is the user's responsibility to install the float. Any error in installation or bending of the float rod will result in overflow of the reservoir in to the bowl. It is likely the overflow of the reservoir is unnoticed.
- This invention provides a toilet flushing system that solves the problems listed above.
- This invention;
- eliminates the flapper seal between the tank and the bowl that are prone to leak;
- uses the leaking water to prevent further leaks;
- alert when leakage occurs;
- allows the user to reset the system to fill the reservoir for every flush after the system's water flow is shut off;
- urges early action by the user in case of water leakage due to the inconvenience of resetting each flush;
- can be added into existing conventional toilet flushing systems;
- eliminates condensation on the water tank surface occurring in existing systems;
- can be mounted at a higher elevation than that of a ceramic tank that is mounted right on top of the bowl. Water from higher elevation increases the velocity in which water enters the bowl resulting in better flushing of bowl surface. This is especially true when the quantity of the flushing water is restricted;
- allows the use of more than one reservoir to eliminate wait time between flushes or if additional water is required for a flush;
- allows full flush or partial flush of any fractional quantity compared to half or full flush capability of currently existing flushing system;
- can be operated by an electronic control system including touch free operation.
- Today's toilet flushing systems do not provide a comprehensive solution.
- Only a dual flush mode is available to conserve water is available. This invention allows the use of any quantity desired as against the half or full dispensing offered by the dual flush. The dual flush option requires a separate system whereas this invention does not. The patents that teach the art of shutting down the water flow in case of a leak puts a user in a predicament of not being able to flush since they do not teach methods to intermittently override the disablement of the flushing system.
- No toilet flushing system that eliminates all failure modes in a simplistic arrangement of systems that is cost effective is available today.
- A toilet flushing system that does not use the flapper valve system is siphoning the flush water into the bowl.
- In summary, there is no commonly known toilet flushing system is totally leak proof.

FIG. 1 is a perspective view of the cylindricalreceiver flushing system 20 installed in a fluidly communicative manner above thetoilet bowl 10. -
FIG. 2 is an exploded view of the cylindricalreceiver flushing system 20. A water source for the flushing system is established through aconnector 21 attached to amaster valve 22 which is normally open. Afill valve 23 which is normally open is connected down stream ofmaster valve 22. Thefill valve 23 discharges water intofill chamber 24 that is fluidly connected to acylindrical receiver 25 through anopening passage 26. Thefill valve 23 discharges a small stream of water into thebowl 10 through a branch tube, not shown in figure, during the filling operation. It is obvious thecylindrical receiver 25 and fillchamber 24 maintain same water level during the filling operation. Afill valve float 27 is attached to thefill valve 23 in a manner to open and close it. Thefill valve float 27 moves up and down in thefill chamber 24 according to the water level infill chamber 24. When the water in thefill chamber 24 reaches a set level thefill valve float 27 completely closes thefill valve 23. The connection between thefill valve float 27 and thefill valve 23 can be adjusted to establish the fill level to desired limit. Now the system is ready for flushing operation. During flushing operation water from thecylindrical receiver 25 is expelled and guided into thebowl 10 through aflush water discharge 31. - An
axis rod 28 inside ofcylindrical receiver 25 supports adisplacer pad 29. Thedisplacer pad 29 rotates on theaxis rod 28. The bottom end of thedisplacer pad 29 sweeps the bottom of thecylindrical receiver 25 floor. The side edge of thedisplacer pad 29 sweeps the cylindrical wall of thecylindrical receiver 25. The bottom edge of a fixedpad 30 is at the floor of thecylindrical receiver 25 and one of its vertical edge is attached to the cylindrical wall of thecylindrical receiver 25. The other vertical edge of the fixedpad 30 is at a very close proximity of the axis portion of thedisplacer pad 29. The orientation of the fixedpad 30 anddisplacer pad 29 within thecylindrical receiver 25 and the flushing operation is shown inFIG. 3 ,FIG. 4 andFIG. 5 . -
FIG. 3 shows the water flowing through the valves into thefill chamber 24 and into thecylindrical receiver 25 via thepassage 26. When the water flow stops when the set level of water is reached. InFIG. 1 a torsion spring 32, one end of which is attached to thelid 33 and the other end is attached to thedisplacer pad 29. -
FIG. 3 also represents the system ready for flushing operation as thedisplacer pad 29 oriented in its home position by the torsion spring 32. The flushing operation is carried out by rotating thedisplacer pad 29 from its home position. The volumetric space confined by fixedpad 30 anddisplacer pad 29 and cylindrical wall in the within section of angle α is defined as space α and similarly the space occupied in the angle α is identified as space β. -
FIG. 4 shows thedisplacer pad 29 rotated thereby increasing the space α and decreasing space β. The increase in space decreases the water level in the space and the decrease in space increases the water level in the spaces. When space β decreases during the rotation of thedisplacer pad 29 water overflows into thedischarge 31. It is imperative a small quantity of water seeps into space α through the gap between the pads and walls. No water flows between spaces over the top edge of the fixed and displacer pads. -
FIG. 5 shows thedisplacer pad 29 is rotated very near to end position where angle α is very low and angle β is as high as possible. Most of the water in space β has overflowed into the bowl. After this stage thedisplacer pad 29 is brought back to the home position, as described earlier, by the torsion spring 32. - Partial flushing: An advantage of this flushing arrangement is the capability to flush out any fraction of the water in space β. In
FIG. 1 aflush handle 34 attached to thedisplacer pad 29 hovers over a graduatedguide 35 on thelid 33. The user, guided by the graduatedguide 35, can turn the flush handle 34 to dispense the required amount. This promotes water conservation as it avoids the excessive water usage for small flush requirements. - Leak prevention: A leak is defined as any water that flows uncontrolled into the receiver. The leak could occur due to many reasons including improper setting of the fill level, leakage in connections of the valves, failure of the fill valve to completely close, fill float movement obstruction, etc. In
FIG. 1 aleak chamber 36 is established below themaster valve 22 and is separated from thefill chamber 24 by apartition 37. Amaster float 38 is attached to themaster valve 22 moves up and down to close or open themaster valve 22 respectively. Leak water flows into theleak chamber 36 from a leak directly above theleak chamber 36 and over the top edge of thepartition 36. Increasing water level in theleak chamber 36 lifts themaster float 38 up and fully closes themaster valve 22. The water to the system is shut off and system is deprived of water. Once the leak is rectified, the leak chamber can be emptied and themaster valve 22 opens for regular operation. InFIG. 6 the fill level for thereceiver 90,overflow level 91 across thepartition 37 and flushwater discharge level 92 over thecylindrical receiver 25 are shown. It is to be noted that thedischarge level 92 is reached only in space b shown inFIGS. 3, 4 and 5 which is isolated from thefill chamber 24. This is to ensure the flush water does not enterleak chamber 36. - Alert and temporary reset: In
FIG. 1 an alert-reset bar 39, attached to themaster float 38, moves up along the float. InFIG. 6A when themaster float 38 rises and shuts themaster valve 22, not shown in figure for clarity, the upper end of the alert-reset bar rises above thelid 33 by a height h and provides a visual alert. Depressing the tip of the alert-reset bar 39 in turn pushes themaster float 38 down and opens themaster valve 22 and establishes water flow through it. But, when the tip of the alert-reset bar 39 is let go it no longer keeps themaster float 38 down and themaster valve 22 is closed. This arrangement is a temporary relief until the leak is attended to. -
FIG. 7 is a perspective view of the verticaldisplacer flushing system 50 installed in a fluidly communicative manner above thetoilet bowl 10. -
FIG. 8 is an exploded view of the verticaldisplacer flushing system 50. A water source for the flushing system is established through aconnector 51 attached to amaster valve 52 which is normally open. A fill valve 53 which is normally open is connected down stream ofmaster valve 52. The fill valve 53 discharges water intofill chamber 54 that is fluidly connected to areceiver 55 through anopening passage 56. The fill valve 53 discharges a small stream of water into thebowl 10 through a branch tube, not shown in figure, during the filling operation. It is obvious thereceiver 55 and fillchamber 54 maintain same water level during the filling operation. Afill valve float 57 is attached to the fill valve 53 in a manner to open and close it. Thefill valve float 57 moves up and down in thefill chamber 54 according to the water level infill chamber 54. When the water in thefill chamber 54 reaches a set level thefill valve float 57 completely closes the fill valve 53. The connection between thefill valve float 57 and the fill valve 53 can be adjusted to establish the fill level to desired limit. Now the system is ready for flushing operation. During flushing operation water from thereceiver 55 is expelled and guided into thebowl 10 through aflush water discharge 61. - A
displacer pad 59, is oriented horizontally, with its edges matching the cross section of thereceiver 55. These edges sweep the walls of thereceiver 55. Thedisplacer pad 59 is moves up and down by aflexible cable 60, one end of it is attached to thedisplacer pad 59 and the other end is attached to aflush handle 64. The flush handle rides inside a graduatedguide channel 65 attached to thelid 63. Thecable 60 is rides over apulley 68 for easy operation. - The system is ready for flushing when the receiver is filled to set level of water. By moving the flush handle 64 along the graduated
guide 65, the displacer pad is moved up and down by thecable 60. The downward movement of thedisplacer pad 59 is enabled by its weight or by additional forces such as springs, not shown in the figures. - During upward movement of the displacer pad the water above the pad is overflows into the
bowl 10 guided by adischarge 61. The partial vacuum created below thedisplacer pad 59 is compensated by flow of water fromfill chamber 54 under thedisplacer pad 59 through thepassage 56. To enhance a faster downward movement of thedisplacer pad 59check pads 67 are provided on the top surface that open during the downward movement and close during upward movement.FIG. 9 shows acheck pad 67 fully closed during upward movement andFIG. 10 shows thecheck pad 67 lifted to allow the water flow through thedisplacer pad 59. The tabs under thecheck pad 67 prevent the tab from disengaging from thedisplacer pad 59. - Partial flushing: An advantage of this flushing arrangement is the capability to flush out any fraction of the water above the pad by moving the flush handle 64 only as required.
- Leak prevention: A leak is defined as any water that flows uncontrolled into the receiver. The leak could occur due to many reasons including improper setting of the fill level, leakage in connections of the valves, failure of the fill valve to completely close, fill float movement obstruction, etc. In
FIG. 8 aleak chamber 66 is established below themaster valve 52 and is separated from thefill chamber 54 by apartition 67. Amaster float 58 is attached to themaster valve 52 moves up and down to close or open themaster valve 52 respectively. Leak water flows into theleak chamber 66 from a leak directly above theleak chamber 66 and over the top edge of thepartition 67. Increasing water level in theleak chamber 66 lifts themaster float 68 up and fully closes themaster valve 52. The water to the system is shut off and system is deprived of water. Once the leak is rectified, the leak chamber can be emptied and themaster valve 52 opens for regular operation. InFIG. 9 the fill level for thereceiver 190,overflow level 191 across thepartition 67 and flushwater discharge level 192 over thereceiver 55 are shown. It is to be noted that thedischarge level 92 is reached only in space above thedisplacer pad 59 which is isolated from thefill chamber 54. This is to ensure the flush water does not enterleak chamber 66. - Alert and temporary reset: In
FIG. 8 an alert-reset bar 69, attached to themaster float 58, moves up along the float. When themaster float 58 rises and shuts themaster valve 52, not shown in figure for clarity, the upper end of the alert-reset bar rises above thelid 63 by a height h, and provides a visual alert similar to the set up shown inFIG. 6A with the only difference in the receiver style. Depressing the tip of the alert-reset bar 69 in turn pushes themaster float 58 down and opens themaster valve 52 and establishes water flow through it. But, when the tip of the alert-reset bar 69 is let go it no longer keeps themaster float 58 down and themaster valve 52 is closed. This arrangement is a temporary relief until the leak is attended to. -
FIG. 12 is a perspective view of the troughreceiver flushing system 70 installed in a fluidly communicative manner above thetoilet bowl 10.FIG. 12A is another perspective view of the trough receiver flushing system. -
FIG. 13 is an exploded view of the troughreceiver flushing system 70. A water source for the flushing system is established through aconnector 71 attached to amaster solenoid valve 72 which is normally open. Afill solenoid valve 73 which is normally open is connected down stream ofmaster solenoid valve 72. Thefill solenoid valve 73 discharges water intofill chamber 74 that is fluidly connected to atrough receiver 75 through anopening passage 76. The opening passage is provided with acheck flap 293, inFIG. 14 , that will prevent water flow from thetrough receiver 75 to thefill chamber 74. The bottom of the trough receiver is circular. Thefill solenoid valve 73 discharges a small stream of water into thebowl 10 through a branch tube, not shown in figure, during the filling operation. Thetrough receiver 75 and fillchamber 74 maintain same water level during the filling operation. A fillsolenoid valve switch 77 is attached to thefill solenoid valve 73 in a manner to open and close it. - The fill solenoid
valve float switch 77 moves up to electrically close a circuit providing a voltage to the solenoid of the fill valve and moves down to open the circuit and deenergize the solenoid valve is in thefill chamber 74 according to the water level infill chamber 74. - When the water in the
fill chamber 74 reaches a set level the fill solenoidvalve float switch 77 energizes thefill solenoid valve 73. The range of movement of the fill valve switch can be adjusted to establish the fill level to desired limit. - When the
trough receiver 75 is filled to set level, the system is ready for flushing operation. During flushing operation water from thetrough receiver 75 is expelled and guided into thebowl 10 through anenclosure 81. - A
displacer pad 79 used in this embodiment is of a rectangular shape with four edges. One edge is attached to a shaft supported across thetrough receiver 75 concentric to the cylindrical axis of the trough. The other 3 edges sweep the vertical walls and cylindrical wall of the trough. When thedisplacer pad 79 is rotated on its axis it displaces the water from the trough. - The system is ready for flushing when the trough receiver is filled to set level of water. A
flush handle 84 is attached to the displacer pad's 79 shaft end. By rotating theflush handle 84 hovering over a graduatedguide 85 on theenclosure 81, thedisplacer pad 79 is also rotated. One edge of thetrough receiver 75 on the cylindrical face determines the discharge level of the trough and the rotation of thedischarge pad 79 towards it expels water at that edge. The displacer pad's 79 home position is established for a maximum quantity of water and the pad is returned to home position by atorsion spring 82. One free end of thetorsion spring 82 is attached to thereceiver 75 and the other end is attached to theflush handle 84. Thetorsion spring 82 is biased towards the home position. The rotation of the displacer pad within the trough section is limited by twolimit bars 88 installed across thetrough receiver 75. - In
FIG. 16 aflexible check strip 90 is attached to cover an opening in thedisplacer pad 79. During the rotation of thedisplacer pad 79 towards the discharge end of the trough the check strip swings to close the opening and swings to close during the reverse rotation. This enables the expulsion of water, if any, remaining in the trough during motion towards home position. - Partial flushing: An advantage of this flushing arrangement is the capability to flush out any fraction of the water in the trough by measured rotation of the
displacer pad 79. - Leak prevention: A leak is defined as any water that flows uncontrolled into the trough receiver. The leak could occur due to many reasons including improper setting of the fill level, leakage in connections of the solenoid valves, failure of the fill solenoid valve to completely close, fill float switch movement obstruction, etc. In
FIG. 13 aleak chamber 86 is located below themaster solenoid valve 72 and is separated from thefill chamber 74 by apartition 87. InFIG. 15 amaster float switch 78, shown, is attached to themaster solenoid valve 72 moves up and down to close or open the electrical circuit that energizes themaster solenoid valve 72 respectively. Leak water flows into theleak chamber 86 from a leak directly above theleak chamber 86 and over the top edge of thepartition 87. Increasing water level in theleak chamber 86 lifts themaster float switch 88 up and closes an electrical circuit to energize themaster solenoid valve 52. The water to the system is shut off and system is deprived of water. Once the leak is rectified, the leak chamber can be emptied and themaster solenoid valve 52 opens for regular operation. InFIG. 14 the fill level for thetrough receiver 290,overflow level 291 across thepartition 67 and flushwater discharge level 292 over thetrough receiver 75 are shown. It is to be noted that thedischarge level 292 is reached only in space above thedisplacer pad 79 which is isolated from thefill chamber 74. The water level in thefill chamber 74 drops during the flushing operation. This is to ensure the flush water does not enterleak chamber 86. - Alert and reset in the event of master solenoid valve activation:
- A
bulb 103 is wired in parallel to the master valve solenoid lights up when themaster solenoid valve 72 is energized thus alerting the shutting down of the flushing system. To override the shutting down of the system a push button switch that opens the circuit that powers themaster solenoid valve 72 is pressed. The master valve solenoid is deenergized thereby opening the valve until the push button is released. - Electronic Control System Applicable to this Embodiment
- A programmable electronic control system is used in conjunction with the manual operation of the flush handle to make the system smart and touch free activation.
- The
electronic control system 101 comprises a power source, a computer control board with inputs including touch pad, microphone, switch, etc. This control system is programmed to operate a controllable motor, such as a stepper motor, based on input to the control system. The feedback from the motor, such as load current, input from position sensor, etc. are also used to control the motor. The motor is bidirectional so that the displacer pad can be rotated in either direction. This control system installed on thelid 83 and wired to the solenoid valves, not shown in figures for clarity. Adrive belt 107 connects themotor 106 shaft and thedisplacer pad 79 shaft. The tension on thedrive belt 107 is optimized so that the flush handle 84 can be used to flush while theelectronic control system 101 is active. The programmable controller is can be programmed to respond to commands throughmicrophone 105 for voice activation, ortouch pad 102 for touch control. -
FIG. 31 is a schematic diagram of circuit to activate the solenoid valve in which a voltage source V actuates a solenoid valve SVNO which is normally open and is closed when energized by closing the circuit with switch SW. -
FIG. 32 is a schematic diagram of a circuit to activate a motor M used in flushing controlled by an electronic control system powered by a voltage source V. -
FIG. 33 is a schematic diagram of a circuit to alert and reset a leak. A normally open solenoid valve SVNO is powered by a voltage source V. A light bulb L, wired in parallel to the solenoid valve SVNO, is lit up when the switch SWNO is closed because of a leak. A manual push button switch SWNC opens the circuit for reset operation. -
FIG. 18 is a perspective view of the rollingreceiver flushing system 20 placed in a fluidly communicative manner above thetoilet bowl 10. -
FIG. 19 is an exploded view of rollingreceiver flushing system 120 shown inFIG. 18 . A rollingreceiver support 121 that provides support for rollingreceiver 122 to smoothly roll on an axis. Aflush water channel 123 is attached to the rollingreceiver support 121. The purpose of this channel is to provide a path for the flush water dispensed from the rollingreceiver 122 into the bowl. Below the rollingreceiver 122 is a rolling receiverflow control system 124 that controls the flow of water into rollingreceiver 122. Aflush handle 401 is attached to the rollingreceiver 122 for rolling it on its axis. The flush handle hovers over a graduateddecal 402 to guide the user regarding the extent of flushing. - A rolling
receiver support 121 showingreceiver axis support 131, a support feature for the rollingreceiver 122 and rolling receiver leak water tray support 132, a support feature for rolling receiver leak watertray axis pin 146. - Filling Operation of
Rolling Receiver 122. -
FIG. 20 is a perspective view of the rolling receiverflow control system 124 that shows the flow of water through the system and water is delivered to rollingreceiver 122 and flush water channel 123 (not shown in this figure). The water trap in some types of toilet bowls may need supplemental water to keep the trap functional. Therefore, water is added directly into the bowl during the filling of the container. The rolling receiverflow control system 124 is attached to rollingreceiver support 121, not shown in figures. -
FIG. 21 is a perspective view of the rolling receiverflow control system 124.Water source connector 140 is connected to rollingreceiver master valve 141 which is normally open and controls the flow to rollingreceiver fill valve 142 which is also normally open. The valve is closed when the pin is depressed. These are typical diaphragm valves used as fill valves in commercially available and are operated by pin projecting from the valve body. A rollingreceiver fill tube 143 delivers water to the rollingreceiver 122 andflush water discharge 123 if needed as shown inFIG. 20 . A rollingreceiver leak tray 144 is rotatably located below the valves and connectors to the rollingreceiver support 121 by rolling receiver leak water tray axis pins 146. Water from any leak or overflow is collected by the rolling receiverleak water tray 144. -
FIG. 22 is a perspective view of rollingreceiver fill valve 142 and rollingreceiver 122. The rollingreceiver 122, supported by rollingreceiver axis 122X, rolls in the direction to close rollingreceiver fill valve 142 as it is being filled. In this embodiment rollingreceiver fill valve 142 is activated by rollingreceiver 122 by mechanical link. -
FIG. 23 is a perspective view showing the rollingreceiver 22 has received the set amount of water and closed rolling receiver fill valve 42 thereby stopping the water flow to rollingreceiver 22. -
FIG. 33 is a side view of rollingreceiver 122 that shows the receiver is unfilled. The receiver is designed in such a way that the center ofgravity 320 is located between rollingreceiver axis 122X and the discharge side of rollingreceiver flushing system 120. The design of rollingreceiver flushing system 120 ensures the location of center ofgravity 320 by adapting means including properly locating the rollingreceiver axis 122X, adding springs and mass across it. - When more water is added to the receiver the center of
gravity 320 moves away from the discharge side of rollingreceiver flushing system 120 and passes the rollingreceiver axis 122X. When the required amount of water is received the rollingreceiver 122 rolls into the position to close rollingreceiver fill valve 142 as shown inFIG. 23 . The required amount is defined as the maximum amount of water that can be expelled from the receiver per flushing operation. Thewater level 390 inFIG. 25 is designed to be the level that triggers the closure of rollingreceiver fill valve 142. If the water continues to flow for any reason including a binding of rollingreceiver axis 122X and not reaching the set location, rollingreceiver fill valve 142 not closing completely the water level keeps rising to 391 and flows out of the receiver through 125. The overflowing water is collected by the rollingreceiver leak tray 144 shown inFIG. 26 . - Flushing Operation
-
FIG. 28 is a side view of the rollingreceiver 122 in which the set amount of flush water is filled towater level 390. The receiver is ready to be rolled in the direction of theflush water channel 123. -
FIG. 29 is a side view of the rollingreceiver 122 in which a portion of the water in the receiver is discharged into theflush water channel 123 by manually rolling the receiver on its rollingreceiver axis 122X. -
FIG. 30 is a side view of the rollingreceiver flushing system 120 in which the rollingreceiver 122 is completely emptied into theflush water channel 123 and further rolling of the receiver is restricted. During the flushing operation all the water released from the receiver is discharged only intoflush water channel 123. The design of the system ensures that there is no spillage of flush water into the leak water tray. As soon as the flushing operation starts by rolling the receiver the rollingreceiver fill valve 142 is open and water is being added to the receiver and the filling operation as described before takes place. - Leak Stoppage:
-
FIG. 26 is an elevation view showing the rollingreceiver leak tray 144 without any leak water. The center ofgravity 320 of the tray is between the rolling receiver leak watertray axis pin 146 and the rollingreceiver master valve 141 attachment end. In this position the rollingreceiver master valve 141 remains open allowing the water from thewater source connector 140 pass through it. -
FIG. 27 is an elevation view showing the rollingreceiver leak tray 144 has collected any and all the leaked water causing the center ofgravity 320 to shift between the rolling receiver leak watertray axis pin 146 and the free end of the tray. This shift has caused the rollingreceiver leak tray 144 to tilt from its normal position and to close rollingreceiver master valve 141 through mechanical links. The amount of water collected in rollingreceiver leak tray 144 that closes rollingreceiver master valve 141 completely is ensured by the proper balancing of rollingreceiver leak tray 144 and the force required by mechanical linkage between rollingreceiver leak tray 144 and rollingreceiver master valve 141 by means including mass adjustment across the rolling receiver leak watertray axis pin 146. Improper adjustment will prevent rollingreceiver master valve 141 to close completely and water will overflow from rollingreceiver leak tray 144 and starts collecting in the support. The flushing system is considered leak proof because of the very low probability of rollingreceiver master valve 141 and rollingreceiver fill valve 142 failing at the same time is very low if the system if designed and set correctly. The means of balancing the rollingreceiver 122 and the rollingreceiver leak tray 144 which includes adding mass at strategic locations, spring, counterbalance, etc. is not shown in the figures for simplicity reasons. - Leak Alert and Reset
-
FIG. 26 shows the rolling receiver alert resetbar 145 is attached rotatably to leakwater tray 144. - In
FIG. 27 the leak water tray is tilted around leak watertray axis pin 146 and the rolling receiver alert resetbar 145 is raised up by a height h. The raised portion serves as a visible alert to the user. The means of support of the rolling receiver alert resetbar 145 at its top is not shown in figure. - To over-ride the closing of the rolling
receiver master valve 141 and fill an empty receiver for flushing, the tip of the rolling receiver alert resetbar 145 is pressed and held down. This brings the tray to the pre-alert position and the rollingreceiver master valve 141 is opened. When the receiver fills to the set amount of water the rolling receiver alert resetbar 145 is released and the rolling receiverleak water tray 144 returns to the alert position and the rollingreceiver master valve 141 is closed again. This process can be repeated until the source of the leak is identified and corrected unless the leak in the system does not overflow the leak tray during filling operation.
