Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a displacement regulator. This displacement regulator has a diaphragm box and two electromagnetic valves. The interior space of the diaphragm box is divided by a movable diaphragm connected to a pressure diaphragm bar under the action of a compression spring into a diaphragm space to be vented and a control pressure space to be subjected to a variable control element. Two electromagnetic valves are also connected to the control pressure space for the purpose of selectively venting and creating a control pressure. This control pressure acts against the force of the compression spring of the diaphragm and is created in the control pressure space.

Known displacement regulators of this type are connected to their pressure source via an external two-way magnetocardial valve, allowing arbitrary adjustment of the control pressure within the single-pressure space. This type of displacement regulator is used, for example, to control a governor valve that adjusts the idle speed of an automobile or the like. however,
This type of displacement regulator is often unacceptably time consuming due to the long conduit between the valve and the diaphragm box, as well as the slow adjustment speed and poor dynamic resolution. It has a delay.

Accurate control and regulation requires displacement regulators that are accurate and responsive to small pressure changes.

The aim of the invention is to produce a displacement regulator of the above-mentioned type with the simplest possible procedure as follows. That is, the displacement regulator should be such that it reacts quickly, without any damage to the conduit that would normally occur, and that allows for more dynamic disassembly.

In order to achieve the above objects, the displacement adjuster according to the present invention is characterized by the following points. That is, first, the two valves are provided within the internal space of the diaphragm box,
Each of these Ili is connected to the connection channel of the diaphragm box on the input side, and opens directly into the H111 arsenal pressure space on the output side. Second, 2
The two valves and the control pressure space are designed in such a way that the clearance volume is as small as possible. Thirdly, the guide of the diaphragm is such that the difference between static friction and sliding friction is as small as possible. This displacement regulator can be made to have a significantly faster response. This is because there is no longer a connecting conduit between the diaphragm box and the valve, and the monolithic construction allows for a narrow design with very few void spaces. This largely avoids reaction time delays.

This also leads, in conjunction with other features regarding the diaphragm bar guide, to a very good Guinaminok resolution. very short time,
Even very small steering or pressure signals actually immediately cause a slight reaction of the displacement regulator. Furthermore, the compact design makes it possible to obtain high adjustment speeds. These advantages allow the displacement regulator according to the invention to be used for very complex control and regulation applications. Such control and adjustment could not be performed using displacement regulators without fI' due to their slowness, inaccuracy, and extremely small lift limited by hysteresis. It is.

According to one preferred embodiment of the invention, a diaphragm bar guide based on polytetrafluoroethylene,
For example, a guide plate made of a sintered material coated with polytetrafluoroethylene or filled with polytetrafluoroethylene is used. Such a diaphragm bar guide has a small difference between its static friction and sliding friction, so the hysteresis is particularly low.
It has been found that it is possible to make the height of the displacement regulator extremely fine. Shiriki Shina 75
It is also possible to use suitable materials, in principle polytetrafluoroethylene.

Furthermore, it is desirable to use a valve made of a 7-car hole. The fluff annocar valve has the advantage of a small negative mass moment, which leads to a better reaction mode.
Preferably, solenoid coils each having several solenoid coils are used, each of which has an inner , A fluff anchor is installed. The fluff anchor is under the action of a compression spring, which holds the movable pulp closure member of the associated pulp and forms part of the magnetic terminal. Since the flap anchor allows magnetic flow on the one hand and holds the valve closing member on the other hand, it does not act via a suction bar or the like, resulting in a very compact and robust construction form. reacts quickly and has little tendency to oscillate.

Furthermore, it is desirable to provide a flap anchor, one end of which is rotatably installed on the magnetic terminal with elasticity and stability against vibrations. The other end of the flap anchor holds a pulp closure member mounted on a stable valve seat and biased by a valve spring in a vibration-stable manner toward closing the pulp. -! ,Ta,
It is desirable to provide a means for limiting the minimum distance between the mutually facing ferromagnetic regions of the flap anchor and the core of the coil. Due to the elastic contact of the flap anchor in the magnetic frame, a better magnetic transfer is obtained even if a capture occurs in the actuation Φ.

Since the pulp spring is biased in the direction of closing the pulp, the pulp is closed in a state where no current flows. Therefore, it is possible to obtain a signal that exists instantaneously when no current flows in the correct state. This is because in such a case, the entire control pressure space is completely sealed from the outside. Various means can be used to limit the minimum distance between the aforementioned ferromagnetic regions. For example, f8c movement stops 1f provided on the cover and/or the interior and exterior of the knotted flap anchors located in the opposing contact areas are used. These measures ensure that a selected minimum slit always exists between mutually facing ferromagnetic regions. As a result, the occurrence of the hysteresis phenomenon is prevented. This is +E certain! till if
! This is necessary for the adjustment of l or lS.

The present displacement regulator is further formed as follows. That is,
The flap anchor in the area between the magnetic frame and the inner core has a sufficiently large cross-section for the magnetic flow to pass through, and the area bordering it has a large enough cross section for the transmission of forces up to the valve closing member as well as the valve spring. It is given sufficient strength for. This results in a reduction in size. This is because only the region carrying the magnetic flow requires large dimensions, and it is sufficient for the other regions 1d to have the necessary mechanical strength. flap anchor,
This reduction in the dimensions of the moving parts thus leads to lower control outputs as well as faster reaction behavior.

In the moat, another magnetic frame is provided on the side opposite to the magnetic frame described above, and this magnetic frame is provided with an abutting part for pulp jilling. In some cases, this magnetic frame may form an auxiliary magnetic terminal. In other words, this magnetic frame has the function of supporting the valve spring. This valve spring forms part of the pulping device 1 and is retained by it. The concentric arrangement 4 of the valve spring with the valve closing member allows a particularly advantageous and compact design. If the magnetic frame forms an auxiliary magnetic terminal for the electromagnetic pulp, the magnetic frame will be used for multiple purposes.

In that case, the cross section of the original magnetic frame through which the magnetic flow passes is made to have slightly smaller dimensions.

A particularly desirable embodiment is obtained by providing a storage pocket for the electromagnetic pulp within the diaphragm box. Each of these storage pockets (d) has an external connecting flow path and a flow path to the pressing space forming the valve seat, and a hermetic closing cover. Easily formed by popping, it makes it possible to store and protect individual lube in an airtight state.The shape and arrangement of these storage pockets are determined by the size of the dog, so that the gap space is as small as possible. be done.

[It is best to place the electromagnetic valve in the storage pocket and provide a stable holder for finger movement (fixation). By doing so, even if vibration occurs during operation, , variable (q adjuster id "y6). Preferably, each holder is formed as an elastic support element in the storage pocket.

This support element is made, for example, in the form of a locking disc and can be easily and quickly inserted and then taken out again.

In this regard, for the purpose of fixing the electromagnetic pulp, it is advantageous to provide a protruding gear-like head on the side of the core of the coil opposite the flap anchor.

On this gear-shaped head are pressed the magnetic frames on both sides of the coil on the one hand, and the elastic support elements on the other hand.

This provides an adjustment between the individual pieces of pulp as well as an adjustment of the position of the pulp within the individual storage pockets.

Furthermore, a position indicator is provided within the diaphragm box and mechanically coupled to the diaphragm. Position reporting can also be carried out externally, for example by determining the position of the diaphragm, but the structure described above is advantageous in terms of space and is particularly robust and reliable in operation. be. A position indicator is provided in the form of a voltage divider with a sliding block guided in the direction of movement of the diaphragm, the elastic contact spring of which slides over a resistive surface that is supplied with current. do. Further, the tappet of this position indicator is stably held in contact with the diaphragm against vibration by a relatively soft spring. The current position of the diaphragm and therefore also of the diaphragm bar within the diaphragm box is therefore constantly probed. At any given time, the magnitude of the pressure is gripped by the contact spring from the resistance surface. Preferably, this is done by means of a sliding block with contact springs electrically connected to the two rods. One of the two contact springs slides on the resistance surface and the other slides on the rectification surface. In this way, the current voltage value or resistance value is transmitted to the rectifying surface by the contact spring. It is desirable to provide a non-rotating guide for the ζ1 running block in the casing of the diaphragm box so that the sliding block with its contact springs can have complete pneumatic contact with the shore.

As with the solenoid valve, the position indicator may also be provided in a central storage pocket of the diaphragm box, sealed to the outside. The position indicator (is then installed in the diaphragm box in an extremely easy way and protected against shadows 4 of the near k s 75 et al. This is very important because there are 75 balls that can be completely captured even with a very small lift.

In order to ensure reliable operation of the position indicator, and therefore also of the entire displacement adjuster, it is also possible to provide a circumferential pet guide which is capable of making a difference between static friction and sliding friction. It's important. The position and indicator tappet must be moved with 1 force (even if it is in the S position, it must move according to the diaphragm, and there is a need for movement).

As for the tappet guide, ``Polytetrafluoroethylene'': ・Well, the tappet guide is made of polytetrafluoroethylene whose porous surface is filled with a polytetrafluoroethylene friction agent. Bet guide °′ can be used.

In order to operate the displacement regulator well, it is preferable to install an A4 flow path between the central storage pocket and the control pressure space at a distance from the tappet guide.

If this connecting channel were not provided, there would be a significant delay during the changeover between the tapping and the central storage pocket via the unsealed tappet guide. Due to the movement of the diaphragm, the actuation becomes inaccurate and dust particles enter the unsealed area between the tappet guide and the tappet II! There is. If a connecting flow 4 such as a sawmill is formed, such a gradual flow conversion and the various deficiencies associated with it can be prevented.

In another embodiment, a mixture of bean curds closed in the left column of current flows through the mold. These pulps, by the method already described, make it possible to maintain this signal when the current of 4 m is removed (by rubbing. Therefore, the diaphragm nozzle is at least constant when the current of 7 A is removed. It is maintained in such a state for a period of time.However, in place of Komaru, it is closed in the state where no current flows;/'c N Magnetic valve and no direct current flows. It is also possible to provide an electromagnetic pulp which is opened in the state.

In that case, for example, the control pressure space is vented in the absence of current flow, thereby releasing the diaphragm bar from its resting state. It is advisable to use one of these embodiments depending on the application.

Depending on the application, it may be advantageous to provide an external packing for the diaphragm bar guide, such as leather or felt. This gasket (I: i: must be of low friction, and is intended to prevent dust from entering the diaphragm bar guide, thereby preventing its sliding characteristics from being impaired. Otherwise, a reduction in head and resolution would occur during operation.

The following structure is suitable for the displacement adjuster. That is, a diaphragm box is used, which consists of an upper casing and a lower casing, with the outer edge of the diaphragm provided between them. The upper casing has all storage pockets, air connections, and connection channels, and the lower casing has a diaphragm bar guide.

This results in a structure that is simple, easy to manufacture, and easy to install and disassemble. Regarding ease of manufacture and addition, synthetic resin can be used as the material for the L part casing, and metal can be used as the material for the lower casing. The upper casing is made of resin, the elbow molding, etc. makes it easy to carve, and there are no problems with weight.

A particularly practical design has a central storage pocket for the position indicator and two storage pockets for the electromagnetic pulp, connected to both 1i111, each with connecting channels oriented in opposite directions.

Furthermore, against the diaphragm Il! The end of II has a closing cover which seals the three storage pockets from each other and from the outside. ita,=g,
It has a plug board for 1 yen pulp and a position indicator on the side of the upper casing. This construction is particularly space-saving and easy to handle.

The individual storage pockets allow easy insertion of the nokuru from the end side. A common closure cover for the storage pocket, which facilitates handling, is preferably made of synthetic resin and is joined to the upper casing by ultrasonic welding or gluing. This closure cover must ensure that the individual storage pockets are completely sealed from each other and from the outside.

One practical embodiment includes an external diaphragm spring that biases the diaphragm in the direction in which the weight control pressure space is enlarged, and a connection channel in the reservoir that provides a negative pressure in the ventilation and/or control pressure space. Its characteristics. Basically, it is possible to install a diaphragm spring inside the diaphragm box, but in that case, the clearance space becomes large, resulting in a slow reaction speed. be. On the one hand, ventilation;
On the other hand, the method of applying negative pressure is much more effective in cases where it is possible to use an existing pressure source, such as ambient pressure or negative pressure in the suction pipe, compared to methods that use a different pressure source. The advantage is that there are many.

The procedure described above is advantageous for automatic applications and the like.

According to a further embodiment, a bearing adjuster is conveniently provided integrally within the diaphragm box and connected hypocentrically to the position indicator as well as to the electromagnetic pulp. This control regulator has a control lead leading to the outside. The above structure is favorable to poetry. This is because there is no need for an external electric heater, and in addition to the supply lead wire, only the control lead wire for the theoretical value input is required. Such displacement regulators can be used for various purposes.
It has been in use for a long time, and since each part is integrated, it is sturdy and works reliably within one night.

The displacement regulator according to the invention is useful for a variety of purposes and can be operated pneumatically or hydraulically. Why not operate it pneumatically? One particularly desirable example of a displacement regulator of this type is when operated in conjunction with a carburetor governor or bypass valve. This displacement regulator is used, for example, to implement an electronic accelerator pedal and/or to adjust the idle speed. This displacement adjuster is reliable, and even when used under heavy vibrations, it can operate reliably, has a fast response, and has a large dynamic resolution.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The displacement adjuster shown in FIG. 1 has a diaphragm box,
This diaphragm box is composed of an upper casing 10 made of synthetic resin and a lower casing 12 made of metal. Lower casing 12 is fixed to upper casing 10 by bending portion 14 . A diaphragm 16 is provided between the upper casing 10 and the lower case 12, and this diaphragm 16 divides the internal space of the diaphragm box into a constantly ventilated diaphragm space M and a control pressure space to receive variable control pressure. Divide into S.

The diaphragm 16 is connected to a stabilizing diaphragm point 18 and a central diaphragm bar 20 by a trench to its end. The diaphragm (-20) is kited outward by a slot-shaped diaphragm guide 22.The diaphragm bar guide 22 is held by a guide holder 24 fixed to the diaphragm box.Diaphragm bar guide 22f -Ol
, which has the characteristic that the difference between static friction and sliding friction is small, and for example, one based on polytetrafluoroethylene is used. An external diaphragm spring 26 around the diaphragm bar 2.0 is provided between the lower casing 12 and an interrogation plate (not shown) fixed to the diaphragm bar 20. Ahram 16
and a diaphragm bar 20 coupled thereto,
It is biased in the direction shown in FIG. Thus, the plate 28 fixed to the diaphragm 16 comes into contact with the lower cage 12 when the pressure space is vented. This position corresponds to a selected rest state, which is communicated via a connection of the diaphragm bar 20, indicated generally at 30, to a governor valve or the like. The diaphragm box is connected in any suitable manner via external connection bolts 32 of the lower casing 12.

As shown in FIG. 1, two electromagnetic pulps 34, 36 are provided, which are arranged in eccentrically juxtaposed storage brackets 38, 40 in the upper casing 10. These storage pockets 38, 40 are connected to connecting channels 42, 44 that extend in opposite directions laterally.

A position indicator 46 is installed inside the central storage pocket 48. Storage pocket 48 is located between storage pockets 38 and 40 described above.

These storage pockets 38, 40 and 48 are hermetically sealed to each other and to the outside by a common closure cover 50. This closing cover 50 is likewise made of synthetic resin and is fixed to the upper casing 10 by ultrasonic welding or gluing.

The position indicator 46 in the central storage pocket 48 has a control f111! from the pocket 48! This includes a tappet 52 that projects into the space S, and a spring 54, which will be explained in detail in the description of FIG.

As shown in FIGS. 1 and 2, each solenoid valve 34 , 36 has a coil body (not shown) mounted therein, and has a droplet coil 56 having an inner core 58 . The inner L 58 protrudes from the coil body together with a core pole (not shown) at one end and a gear-like head 60 at the other end. A strip-shaped magnetic frame 62 is provided, which is connected to the magnetic frame 64 in this example, and connects the Lemade coil 56 to a gear-shaped groove 60 and an anti-χ·j
It runs all the way to the edge of the side. Historically, a gear-shaped elastic support element 66 is pressed against the gear-shaped head 60, and this support element 66 has a shape similar to that 11. It has a function of fixing the electromagnetic pulp to which it belongs in the storage pocket by its elasticity (see Fig. 1).

(jt, the solenoid valve is pushed by the lever until it comes into contact with the opening of the storage blur/)l& section. The support element 66 prevents the valve from shifting in the storage cavity, even taking into account the vibrations that occur during operation.

A flap anchor 68 extends over the end of the solenoid coil 56 having the core, and one end of the flap anchor 68 is connected to the end of the cover 62 by means of a resilient pivot bearing 70. pressed against the body.

This pressing force is sufficiently large that even if vibrations during operation are taken into account, the contact between the flag anchor 68 and the cover 62 is always maintained, so that there is sufficient space for the magnetic flow to pass through. A cross section can be obtained. , L-s s and the ferromagnetic part of the flap anchor 68, there is a slit 72 between the minimum and maximum values depending on the position of the flap anchor 68. It is variable. The minimum value ensures that no significant hysteresis phenomena occur and therefore that the difference between the excitation during approach and the excitation during dissociation is as small as possible. This smallest slit 72 is obtained, for example, by a protrusion or a covering of a flag anchor. For this purpose, an external stopper may be provided.

Flap anchor 68 has a flap anchor extension 74 that extends beyond slit 72 and retains a valve closure member 76 at its end. This closing member 76 is provided in the valve seat 78 around the passage to the control pressure space S, at the bottom of the storage pocket to which it belongs. A valve spring 80 is provided between the abutting portion 82 and the extension portion 740 of the magnetic frame 64, and seals the closing member 76 against the valve seat 78 when no current flows through the solenoid coil 56. to press against. A protrusion 84 on the magnetic frame 64 holds the spring 80 in position.

When current flows through the solenoid coil 56, the flap anchor 68 is magnetically attracted against the force of the spring 80, and the slit 72 is pinched and the valve seat 78
The flow path is released. In this way, the control button f in the pressure control space S can be changed as necessary by the action of the sight loops 34 and 36.

In FIG. 3, the position indicator 46 has a slidable sliding block 86 that is
The diaphragm bar 20 is guided in the longitudinal direction of the tappet 52, that is, in the longitudinal direction of the diaphragm bar 20, and is prevented from rotating by the guide 88. Sliding block 86 holds contact springs 90 and 92 electrically connected to the two redoubts. The contact spring 90 is
It slides on a resistance surface 947 extending in the direction of movement of the displacement regulator. Both ends of this resistive surface are pierced to external prongs (not shown) in a manner that will only be shown briefly. In the figure (d,
Although only one end of the resistive surface 94 is shown, the resistive surface 94 may be connected to a plug 100 of a plug board 102 via a concentric contact 98.
02 is provided on one side of the upper case/nog 10. The other end of the resistive surface 94 as well as other electrical connections on the displacement regulator are made in any suitable manner as part of the plug board 102. The other contact spring 92 of the sliding block 86 slides over a commutating front 96 extending in the direction of movement of the displacement regulator, but also for these electrical connections.
The same can be said. By means of the tappet 52 and the spring 54 the sliding pump o7 always responds to the ft7-R of the diaphragm 16, i.e. the diaphragm no. 20.
The position of the resistor 86 is thus captured as the electronic signal of the resistor 1ii94 or the resistor +A- signal, and the position of the resistor 96 before rectification is
and via the plug board 102 to the outside 5.

(t The tappet 52 of the tVt indicator 46 passes through a socket-shaped tappet guide 104 and projects into the control pressure gap S. Similarly, this tappet kite 104 also has a gap between static Iyl friction and sliding friction. The difference is as small as town [;hi]. In this case as well, it is preferable to use polytetrafluoroethylene as the base material. At a distance from the tappet guide 104, the channel 10
6 must be provided between the storage pocket 48 and the control pressure space S so that there is only a time delay in the flow change between the two holes. If such a device were not provided, the flow diversion would affect the movement of the diaphragm 16, and the dirt would then enter the loose parts of the tappet guide 104, damaging its slide feature t7fg. Become. The spring 54 must be weak enough not to affect the position of the diaphragm 16, which is shaken by the pressure, and at the same time, the spring 54 must be weak enough not to affect the position of the diaphragm 16, which is shaken by pressure.
f″12 must be strong enough to maintain contact between 6 and 6.

In this example, plug board 102 includes plug 100
It has 7 books. That is, two each for solenoid valves 34 and 36, and position: lid indicator 4.
3 for 6. Of the three position indicators, two are for supplying voltage to the resistive surface 94 and the other is for capturing the signal from the rectifying surface 96.

If desired, a bearing adjuster can also be provided in the storage pocket 48 together with a position indicator 46 and connected either on the outside via the plug board 102 or on the inside to a solenoid valve.

In the case of an internal connection, the external connection of the commutating surface 96 is not required, and instead a bearing adjuster plug for the theoretical innoput is provided.

The displacement regulator according to the present invention has a small diameter, tonne, h), and makes it possible to obtain high adjustment performance while using a minimum amount of electric power (goods) energy.

Therefore, it is possible to print books with simple operation and low power. This displacement adjuster is extremely high IW
It has a very rapid reaction rate. Therefore, no matter how small or how fast the signal changes, it is immediately converted into the corresponding head. By arranging the groove 1>2 elements together in the diaphragm box, flow-dependent conduction losses and disadvantageously large clearance spaces are avoided. Since the individual parts of the displacement Ji repair equipment are held stable against vibrations (1+1), even if they are used [heavily] in automobiles, etc., I (t et al. 7), Ru.

Therefore, an appropriate power transmission mechanism such as a step motor or a DC motor can be used.1. ii〆7;
By replacing the displacement regulator 14 with a displacement regulator according to the present invention, it is possible to control or adjust the speed governor, bypass valve, etc. to an arbitrary displacement extremely accurately.
