Description

[001] This invention patent application is divided from BR112018014630-7, filed on 02/21/2017.

[002] The invention relates to a valve actuation device, with a manual control element and a valve actuable by a manual control element, wherein a control element is in operational connection with the control element. manual, in which the valve is operable with a distal end of the control element and in the operative connection between the control element and the manual control element a compensation device is arranged, which has a piston movably guided to a control element. housing and allows relative movement of the manual control element in relation to the control element, and a return element is present, which uses a counteracting force against the relative movement.

[003] Such valve actuation devices are known and used to manually separate an outlet stream from an inlet stream or manually connect the outlet stream and the inlet stream when necessary.

[004] From patent document EP 1 548 344 B1, a valve actuation device with the characteristics described in the introduction is known, in which the plunger is formed in the manual control element and the housing element is formed in the element command. A replacement element is in this case arranged in the housing element and thus in the compensation device or buffer device.

[005] The invention aims to provide an alternative to the solution according to patent document EP 1 548 344 B1.

[006] The objective is achieved by the characteristics of claim 1. In particular, it is thus proposed to solve the above problem in a valve actuation device of the type described above, in which the replacement element is arranged outside the valve actuation device. compensation. Thus, obstacles to the mobility of the piston are avoided by means of the replacement element in the housing element.

[007] Alternatively, the task is solved according to the invention by the characteristics of the second independent claim. In particular, it is proposed to solve the problem of the above task in a valve drive device of the type described above, that the plunger is designed at a proximal end of the control element. Thus, it is easily possible for the plunger and the control element to be made of the same material. It is also possible for the housing element and the control element to be made of different materials. This is favorable because the housing element as a complex shape can easily be made of plastic, while for the control element to achieve a higher load capacity and bending resistance, a metallic material may be more suitable. It is particularly favorable if this embodiment is combined with the above-described first embodiment according to the invention.

[008] In an embodiment of the invention it can be provided that the housing element of the compensation device is fixedly disposed on the manual control element. Thus, the housing element is easily and safely operable and adjustable from the outside.

[009] In an embodiment of the invention it can be provided that the housing element has a plunger removal opening laterally open and/or transversely open in relation to the plunger guide direction. Therefore, the plunger can be easily inserted during manufacturing.

[0010] In an embodiment of the invention it can be provided that the housing element forms a stop against which the replacement element pushes the piston to a rest position. Therefore a resting position is malleable.

[0011] Alternatively, the task is solved according to the invention by the characteristics of the third independent claim. In particular, for the solution of the aforementioned task in the case of a valve actuating device of the type described above, a regulating device is formed, with which a maximum distance is adjustable - for example for an open position of the valve - between a valve seat of the valve and the distal end of the control element. The advantage here is that a positioning stroke, which the valve, especially one, for example the valve element described below, can perform, is limitable between a closing position and an opening position. Therefore, intermediate positions between the closed position and the open position are adjustable so as not to completely open the valve. The maximum distance between the valve seat and the distal end of the control element can be adjusted, for example, by the fact that with the regulating device a maximum distance between the manual control element and the distal end of the control element - for example in the case of an extended piston in the housing element of the compensation device - it is adjustable or adjusted. For example, for this purpose, the control element can be moved independently of the manual control element, or the manual control element independently of the control element, to its position. Alternatively or additionally, the maximum distance between the valve seat and the distal end of the control element can be adjusted by the fact that the manual control element in conjunction with the control element is adjustable in position.

[0012] In an embodiment of the invention it can be provided that the regulation device is arranged between the compensation device and the manual control element. Therefore, a compact actuation device can be designed. The regulating device can be easily arranged outside a sealed area of the valve. It is advantageous in this case if the regulating device is designed to adjust the distance between the compensation device and the manual control element. Therefore, a simple limitation of the valve positioning stroke can be achieved by moving a rest position of the piston in the housing element.

[0013] In an embodiment of the invention, it can be provided that the adjustment device has a movement thread. Thus, a conversion of a rotary command movement into a movement, which results in an adjustment of the mentioned maximum distance. For this purpose, the manual control element is preferably rotatably or tiltably mounted, particularly preferably around an axis directed at the valve. To actuate the aforementioned closing element, the additionally displaceable manual control element can be installed in particular on the valve. This facilitates operability since a user can easily distinguish between manual operation by pressing and adjusting intermediate positions by rotation.

[0014] In an embodiment of the invention, it can be provided that the adjustment device has a support spring, with which an extension movement can be supported. In this way, smooth operability is achievable.

[0015] In an embodiment of the invention it can be provided that the valve has a pressure chamber, which is connected through a filling opening, to an inlet flow of the valve and through an outlet flow opening, to an outflow flow from the valve, wherein with the pressure chamber a valve valve element that separates the outflow from the inflow, is operable and wherein the outflow opening with a closing element can be opened and closed. Thus, a servo actuator is formed, which produces a reinforcement of an actuation force applied to the manual control element by a water pressure present in the inlet flow. The described compensation device makes it possible in this case for the closing element to be tracked or traceable with the valve element when pressure builds up in the pressure chamber and the valve element is pressed into the closed position. Thus, the outlet flow opening can be kept closed, wherein the closing element is movable with the valve element. Therefore, a drive can be exerted with relatively little effort. Reinforcement can in this case be obtained via the pressure chamber, which can be switched via the control element between a filled, pressurized and therefore closed state and an emptied, release state. Preferably, the closing element is disposed at the distal end of the control element. Therefore, additional transmission elements between the control element and the closing element can be dispensed with. This simplifies the project structure.

[0016] In an embodiment of the invention it can be provided that, for example, the pressure chamber of the aforementioned valve is sealed in relation to the manual control element by a seal. Thus, the end of the pressure chamber in relation to the outside is easily accessible. In particular, it may be provided that the seal is in contact with the control element. Thus, an entry of the control element into the pressure chamber is possible. Alternatively or additionally, it can be provided here that the seal is in contact with the compensation device. Therefore, an alternative introduction of a driving movement into the pressure chamber, in particular to adjust one, for example the already mentioned, closing element, is possible. The seal is, in this case, preferably respectively moved together with the control element or fixed to one, for example the aforementioned housing part. This allows for a structurally simple configuration of the seal.

[0017] In one embodiment of the invention, it can be provided that the valve element is suspended in a, preferably, for example, the already mentioned filling opening, for example, in the elastic membrane that supports the already mentioned pressure chamber . Therefore, the filling opening is easily moved together with the membrane and/or a valve element fixed thereto, which allows self-cleaning during operation, for example with a cleaning pen.

[0018] In an embodiment of the invention it can be provided that, for example, the already mentioned pressure chamber is limited by one, for example, by the already mentioned housing part and one, for example, by the membrane fixed to the upper part. accommodation already mentioned. Therefore, a substantially double-shell pressure chamber can be designed, which is easily manufactured. Particularly favorable in this case is a combination with the already mentioned seal in relation to the manual control element. In particular, it can be envisaged here that the membrane is clamped between the housing part and another housing part. Therefore, a simpler and more airtight membrane retention can be obtained close to the carcass part. Preferably, the other shell part forms at least the outflow. Thus, the additional housing part can be provided with an additional function, in particular with the provision of the already mentioned valve seat.

[0019] In an embodiment of the invention it can be provided that, for example, the aforementioned outlet flow opening of, for example, the aforementioned pressure chamber of the valve, is arranged in an extension of the control element. Therefore, one, for example the already mentioned, closing element can be easily and directly controllable to open and close the outlet flow opening through the control element, in particular if it is in the form of a rod.

[0020] In one embodiment of the invention it can be provided that, for example, the aforementioned inlet flow can be separated from one, for example, of the already mentioned outlet flow through an annular valve seat, e.g. by the aforementioned valve seat. Therefore, the function of the valve valve is easily controlled. The valve seat can serve as a support for the aforementioned valve element.

[0021] In an embodiment of the invention it can be provided that, for example, the aforementioned outlet flow is arranged in an extension of the outlet flow opening. Thus, a space-saving design becomes viable in which, for example, the control element, the closing element and the valve element are arranged one behind the other in an imaginary line.

[0022] In one embodiment of the invention it can be provided that the replacement element activates the control element. Therefore, an immediate application of the reset force on the control element can be achieved. A space-saving design is also possible. The replacement element may in this case, for example, be tensioned or pressurized. Preferably, the control element is pressurized by the replacement element. This allows a structural dimension along the control element with which replacement force support is easily achieved.

[0023] In one embodiment of the invention, it can be provided that the replacement element is supported, for example, next to an already mentioned housing part. Therefore, a fixed thrust bearing can be provided.

[0024] Alternatively or additionally, it may be provided in an embodiment of the invention that the replacement element is supported on the manual control element. This allows for a floating support, where a support on a housing part is not necessary. This can be constructively advantageous if, for example, space conditions are tight.

[0025] In one embodiment of the invention it can be provided that the replacement element is a helical spring. Therefore, a replacement force with a structurally simple component can be developed. A replacement force along the control element is easily developable. Preferably, the coil spring receives the control element. Thus, space can be saved.

[0026] In one embodiment of the invention it can be provided that the manual control element is influenced by a spring for replacing the manual control element. The advantage here is that it is possible to obtain a reset of the manual control element independently of the compensation device. In particular, it can be envisaged in this case that the reset spring of the manual control element develops a greater force than the reset element. Therefore, it is easy to achieve that the reset spring of the manual control element can overcome the reset force of the reset element. On the other hand, the reset forces of the reset element on the one hand and the reset spring of the manual control element on the other hand are preferably aligned in parallel and/or in opposite directions. Preferably, it is provided that the reset spring of the manual control element is supported, for example, in the aforementioned part of the housing. Thus, an axial bearing for the manual control element is formed.

[0027] In one embodiment of the invention, it can be envisaged that the manual control element replacement spring is designed as a helical spring. Helical springs represent structurally simple components to develop, for example, a straight-aligned replacement force. Preferably, it is provided that the reset spring of the manual control element engages the control element and/or the compensation device. Therefore, a space-saving arrangement is possible.

[0028] In an embodiment of the invention it can be provided that the manual control element houses or engages the compensation device and/or the control element at least partially in a dome shape. Therefore, a small longitudinal dimension of the device can be obtained.

[0029] In one embodiment of the invention it can be provided that the manual control element is adjustable through an attack point of the control element. Preferably, the compensation device allows for this adjustment capability. The advantage here is that a bistable drive mechanism, for example a push-push locking mechanism such as a ballpoint pen mechanism or a central cam mechanism, can be commanded in which a change from one stable position to another stable position , by adjustment beyond the other stable position and subsequent return to the other stable position becomes possible. Here, the return element allows the necessary freedom of movement between the housing element and the piston, as the control element is not in the other stable position in which the valve closes, for example, it can move outward. The replacement element can thus simultaneously transmit a driving force for valve adjustment.

[0030] In one embodiment of the invention it can be provided that the manual control element is adjustable in parallel to the control element. Therefore, an actuation direction and a positioning direction coincide and a small lateral structural dimension in relation to a drive direction is achievable.

[0031] In an embodiment of the invention it can be provided that the control element is designed in the shape of a rod. A linear actuation is therefore structurally easily accessible. A lateral structural dimension is short-lived.

[0032] In one embodiment of the invention, it can be foreseen that the control element has a thickening of the cross section at an end away from the valve. Therefore, a stop can be formed, with which the control element in a rest position, in one, for example, in the aforementioned housing element of the compensation unit, is durable.

[0033] In an embodiment of the invention it can be provided that the control element is arranged in a displaceable manner. Therefore, the control element is simply linearly conductive. Alternatively or additionally, it may be provided that the compensation device is arranged in a displaceable manner, in which its linear guidance can be achieved.

[0034] In one embodiment of the invention it can be provided that the control element is slidably mounted on, for example, the aforementioned housing part. This facilitates easy driving of an adjustment movement of the control element. Alternatively or additionally, it may be provided that the compensation device is displaceably mounted on, for example, the aforementioned part of the housing. Therefore, the compensation device is driveable with little design effort.

[0035] In one embodiment of the invention it can be provided that the housing element and/or the manual control element are connected to a bistable drive mechanism. Therefore, the valve can be adjustable between an open position and a closed position, which represent stable positions. For example, the drive mechanism as a push-push locking mechanism, in particular as a ballpoint pen mechanism and/or as a heart cam mechanism can be formed. This allows for easy activation and easy switching between positions, as the user only needs to press to achieve the change.

[0036] To solve said task, it is described according to the invention alternatively or additionally to that previously described in the case of a valve actuation device, especially as previously described and/or provided according to one of the claims, that the valve actuation device is provided with a manual control element and a valve actuable through the manual control element, one control element being in operative connection with the manual control element, the valve being actuable with one end distal to the control element and is arranged in the operative connection, a compensation device, which has a piston movably driven to a housing element and allows relative movement of the manual control element against the control element, and being that a replacement element is present that uses a replacement force against relative movement, and the valve has a pressure chamber, which is connected through a filling opening, to a valve inlet flow, being with the chamber of pressure a valve element of the valve, which separates the output flow from the input flow, is operable and the opening of the output flow can be opened or closed with a closing element, characterized by the fact that an area of cross-section that can be covered with the closing element at the outlet flow opening is greater than a cross-sectional area of the control element at its exit out of the pressure chamber. Therefore, it is avoidable that - for example, in a pressure shock mediated in the pressure chamber - the closing element automatically distances itself from the outlet flow opening and releases it uncontrollably. A further advantage is that a reset element, for example the reset element already described, with which the closing element can be transferred to its closed position, can be provided with a small spring force. This has the additional advantage that a manual control element return spring, for example the manual control element return spring already described, which forces a return movement of the manual control element, also does not need to be dimensioned with great spring force. In this way, smooth switching behavior can be achieved.

[0037] In this case, it is preferably provided that the closing element is arranged at the distal end of the control element. Therefore, a command from the closing element - for example via the manual command element already described - is easily executable. The cross-sectional area that can be covered can, for example, be at least twice as large as the cross-sectional area of the control element. For example, the cross-sectional area that can be covered can be defined by a pilot valve seat that interacts with the closing element.

[0038] In an embodiment of the invention it can be provided that in the valve element a pilot valve seat is formed which can be closed and released with the closing element and that the outlet flow opening in the flow direction behind the pilot valve seat forms a preferably funnel-shaped narrowing. The advantage here is that the outlet opening can be designed as small as possible, for example, in diameter at most half or even at most a quarter the size of the pilot valve seat.

[0039] To solve said task, it is provided according to the invention alternatively or additionally to what has been described previously described in the case of a valve actuation device, especially as previously described, and/or according to one of the claims, which the valve actuation device is provided with a manual control element and a valve and a valve actuable through the manual control element, one control element being in operative connection with the manual control element, the valve being operable with a distal end of the control element, the valve having a pressure chamber, which is connected through a filling opening to an inlet flow of the valve and through an outlet flow opening connected to a flow of outlet of the valve, with the pressure chamber being a valve element, which separates the output flow from the input flow, is operable and the outlet flow opening with a closing element, which is preferably arranged in the connection at the distal end of the control element, can be closed or open, characterized by the fact that a flexible pipe is placed in the outlet flow opening, which also projects in the case of an open valve into the outlet flow and prevents backflow out of the main flow path from the open valve to the outflow opening. Thus, a flexible pipe in the same direction is provided that keeps the main flow away from the mentioned pilot valve. Therefore a resistance against closing of the pilot valve, which is developed by the main flow, can be reduced. Thus, it can be achieved that the pilot valve can be closed even at high pressures in the main flow path.

[0040] In the case of an embodiment of the invention, it can be envisaged that a length with which the valve element projects with the flexible piping in the closed position of the valve for the outflow is at least 1.5 times, preferably at least twice a lifting height of the valve element.

[0041] The invention will now be explained in more detail with reference to exemplary embodiments, but is not restricted to these embodiments. Other embodiment examples result from combining the characteristics of one or more protection claims with each other and/or with one or more characteristics of the embodiment examples.

[0060] figure 18 shows a detail of figure 17 and

[0062] Figure 1 and Figure 2 show a valve actuation device 1 according to the invention in longitudinal sectional views rotated 90° relative to each other. Figure 3 shows the valve actuation device 1 in a three-dimensional oblique view.

[0063] The valve actuation device 1 has a manual control element 2 with which a valve 3 disposed within the valve actuation device 1 can be switched between a closed position and an open position.

[0064] Between the manual control element 2 and the valve 3, a control element 4 is arranged, which mediates an operating movement in the manual control element 2 for the valve 3.

[0065] At a distal end 5, the control element 4 is connected to the valve 3 in such a way that the valve 3 is switchable with the control element 4 between the open position and the closed position.

[0066] Between the manual control element 2 and the control element 4, a compensation device 6 is formed, which mediates an action from the manual control element 2 to the control element 4.

[0067] For this purpose, the compensation device 6 has a housing element 7, in which a piston 8 is linearly slidably guided.

[0068] This freedom of movement makes control 4 movable in relation to manual control element 2.

[0069] In order to maintain the control element 4 in a preferred rest position with respect to the manual control element 2, a return element 9 is formed. This return element 9 develops a reset force to maintain the control element. control 4, if the position of this control element 4 allows, in the rest position shown in Figure 4 and in Figure 5 in the housing element 7.

[0070] We can see from the illustrations that the replacement element 9 is arranged outside the compensation device 6 and, in particular, outside the housing element 7. Thus, the obstruction of the sliding movement of the piston 8 in the housing element 7 is avoidable. The plunger 8, which is guided in the housing element 7, is formed directly at the proximal end 10 of the control element 4.

[0071] The housing element 7 of the compensation device 6, however, is connected via a coupling connection 11 fixed to the manual control element 2.

[0072] Through the longitudinal axis 12 of the valve drive device 1, a piston guide direction is predetermined, along which the piston 8 is displaceably guided in the housing element 7.

[0073] Transverse to this piston guide direction, the housing element 7 is provided with a piston withdrawal opening 13, through which the piston 8 can be laterally inserted into the control element 4.

[0074] This allows for a one-piece design of the plunger 8 in the control element 4.

[0075] Valve 3 has a pressure chamber 14, which is connected through a filling opening 15 with an inlet flow 16 from valve 3.

[0076] A cleaning pin 17 prevents the filling opening 15 from becoming clogged.

[0077] As soon as water pressure is present in the inlet flow 16, the pressure chamber 14 is thus filled through the filling opening 15.

[0078] The pressure chamber 14 is connected through an outlet flow opening 18 with an outlet flow 19 of the valve 3.

[0079] With the valve element 20, the outlet flow 19 is separable from the inlet flow 16.

[0080] At the distal end 5, the control element 4 is connected to a closing element 21.

[0081] In the valve element 20, the outlet flow opening 18 is designed correspondingly to the closing element 21, which - depending on the position of the manual control element 2 - with the closing element 21, can be closed or opened , that is, it is releasable.

[0082] With the closing element 21 it is thus controllable, whether in the pressure chamber 14 through the filling opening 15, a pressure is established, which is the case for closed outlet flow opening 18, or if this pressure is established is degraded again, in which the outflow opening 18 is released by the closing element 21. For this purpose, an opening diameter of the outflow opening 18 larger than an opening diameter of the filling opening 15 is selected. is selected.

[0083] When the established pressure is increased, the valve element 20 is thus pressed against the outlet flow 19 in order to separate the inlet flow 16 from the outlet flow 19. In the case of the pressure chamber 14 (with the outlet flow opening 18 open), the pressure in the inlet stream 16 causes the valve element 20 to be pushed out of the inlet stream 16 and releases this inlet stream 16. The valve 3 is then transferred to its position open.

[0084] Figures 4 and 5 show an intermediate position in which the closing element 21 has already been released from the outlet flow opening 18 to release it. However, the pressure in the pressure chamber 14 is not yet degraded, so that the valve element 20 continues to close the outlet flow 19.

[0085] The control element 4 is disposed in the pressure chamber 14. The pressure chamber 14 is sealed against the manual control element 2 by a seal 22. The seal 22 in this case rests against a part of the housing 23 and is moved together with the compensation device 6.

[0086] The pressure chamber 14 is closed by an elastic membrane 24. The membrane 24 carries the valve element 20 and the filling opening 15 formed in the valve element 20.

[0087] The aforementioned housing part 23 and the membrane 24 thus delimit the pressure chamber 14.

[0088] The membrane 24 is in this case retained between the housing part 23 and another housing part 25, which forms the inlet flow 16 and the outlet flow 19.

[0089] It can be seen from the drawings that the outlet flow opening 18 and the outlet stream 19 are arranged in an extension of the control element 4 along the longitudinal axis 12, i.e. along the direction of travel. of control element 4, one after the other.

[0090] Sealing the outlet flow 19 with respect to the inlet flow 16 through the valve element 20 is achieved as the valve element 20 is pressed into the closed position according to Figure 1 and Figure 2 by pressure in the pressure chamber 14 against a valve seat 26 in the outlet flow 19.

[0091] The replacement element 9 is designed as a helical spring and pressurizes the control element 4. Here, the replacement element 9 is supported on the housing element 7 next to the manual control element 2.

[0092] The manual control element 2 is driven by a manual control element replacement spring 27, which is supported in the housing part 23.

[0093] The reset spring of the manual control element 27 in this case develops a greater force than the reset element 4.

[0094] Both the replacement element 4 and the manual control element replacement spring 27 are designed as helical springs that surround the control element 4 and house it within itself.

[0095] The compensation device 6 is also arranged, at least partially, on the reset spring of the manual control element 27.

[0096] The manual control element 2 is designed in the shape of a dome and houses the compensation device 6 inside 28.

[0097] Here, the manual control element 2 is held in a sleeve 29, which forms a stop on the manual control element 2.

[0098] Figures 1 and 2 show the valve 3 in the closed position in which the closing element 21 closes the outlet flow opening 18. This closure is for the accumulation of pressure in the pressure chamber 14, already necessary when the element valve seat 20 has not yet reached valve seat 26. At this point, therefore, manual control element 2 must already be in the lower position. In order to allow the valve element 20 to follow, pressing the manual control element 2 causes the piston 8 to move first in the housing element 7. With the descending valve element 20, the tension of the reset element 9 causes the piston 8 to move back to its stop in the housing element 7.

[0099] Furthermore, the mobility of the plunger 8 in the housing element 7 allows the manual control element 2 to move beyond one end of the adjustment path for the control element 4, predetermined by the closing element 21. This It is advantageous in the case of a push-push locking mechanism, as it is possible to overcome the bottom dead center (in relation to the push-type movement) or the stable point in order to recover the manual control element.

[00100] From figure 1, in comparison with figure 4, it can further be seen that the manual control element 2 is adjustable parallel to the control element 4 along the longitudinal axis 12.

[00101] In order to allow for a question regarding a limitation of the housing element 7, the piston 8 is designed as a cross-sectional thickening 30 at the proximal end 10 of the control element 4. In the example embodiment, this thickens - ment of cross section 30 is connected to the control element 4 in one piece and integrally molded over it.

[00102] A bistable drive mechanism 31 with a clamp 32 and a control groove 33 forms a push-push type locking mechanism, such as a ballpoint pen mechanism or a heart cam mechanism, with which the manual control element 2 in the housing part 23 is adjustable between an upper position (Figure 4 and Figure 5) and a lower position (Figure 1 and Figure 2) by pressing along the longitudinal direction.

[00103] These two adjustment positions allow, in the manner described by establishing pressure or reducing pressure in the pressure chamber 14, the closed position (Figure 1 and Figure 2) and the open position (Figure 4 and Figure 5) of the valve.

[00104] Figures 7 to 12 show another example of embodiment of a valve actuation device according to the invention. Components or functional units that are functionally and/or structurally in relation to components or functional units of the preceding exemplary embodiment, the same or of similar type, are designated by the same reference numerals and will not be separately described again. Therefore, the embodiments in relation to figures 1 to 6 apply in accordance with figures 7 to 12.

[00105] The example embodiment according to Figures 7 to 12 differs from the preceding example embodiment in that the seal 22 is fixed to the housing part 23, so that the control element 4 is guided through the part 23 housing to the outside. The compensation device 6 is therefore located behind the seal 22 and therefore outside the pressure chamber 14. The seal 22 is applied to the control element 4.

[00106] The example embodiment according to Figures 7 to 12 differs from the preceding example embodiment in that the replacement element 9 is supported on the housing part 23. So that the manual control element 2 can transfer the element of control 4 to the position that opens the outlet flow opening 18, the manual control element return spring 27 is designed stronger than the replacement element 9.

[00107] The control element 4 is displaceably arranged in the housing part 23. In figures 7 and 8, the closed position of valve 3 is again shown, while figures 10 and 11 show the open positions of valve 3.

[00108] We can see that in figures 7 and 8 the closing element 21 closes the outflow opening 18, while the closing element 21 in figures 10 and 11 releases the outflow opening 18, so that the pressure chamber 14 is relieved.

[00109] Figures 7 to 16 show another example of embodiment of a valve actuation device according to the invention. Again, components and functional units that are structurally and/or functionally similar or identical to the components or functional units of the preceding exemplary embodiments are indicated by the same reference numerals and will not be separately described again. Therefore, the embodiments in relation to figures 1 to 12 apply in accordance with figures 13 to 16.

[00110] The embodiment according to figures 13 to 16 initially shows the closed position of the valve 3 in figure 13, in which the closing element 21 closes the outlet flow opening 18. Thus, in the pressure chamber 14 Through the filling opening 15 from the inlet flow 16 a pressure is established, which presses the valve element 20 on the valve seat 26.

[00111] Figure 14 shows an intermediate position in which the manual control element 2 is already being moved to the upper position. This is done by pressing the manual control element 2, in which the bistable adjustment mechanism 31 has been transferred to the upper position.

[00112] In this situation, the closing element 21 releases the outlet flow opening 18. However, since pressure is still present in the pressure chamber 14, the valve initially remains in its closed position.

[00113] However, the outlet flow opening 18 is - as already mentioned - sized larger than the fill opening 15, so that the pressure in the pressure chamber 14 through the outlet flow opening 18 and the flow output 19 is reduced.

[00114] As a result, the pressure in the inlet flow 16 lifts the membrane 24 with the valve element 20, so that the valve 3 is opened.

[00115] This state is illustrated in figure 15.

[00116] The exemplary embodiment according to figures 13 to 16 differs from the preceding exemplary embodiments in that an adjustment device 34 is additionally formed between the compensation device 6 and the manual control element 2, with which a maximum distance , i.e. a distance with maximally extended control element 4 from the housing element 7 is adjustable between the closing element 21 and the manual control element 2. In this way, the maximum distance between the valve seat 26 and the distal end 9 of the control element 4, i.e. a distance between the valve seat 26 on the one hand and the distal end 9 and the fixed closing element 21 on the other hand, is adjustable in the open position of the valve 3. An opening cut in the valve seat 26 in the open position is therefore changeable.

[00117] This is possible due to the fact that a movement screw 35 is formed next to the manual control element 2, with which a rotational movement of the manual control element 2 can be defined in a displacement movement along the longitudinal axis 12 of a glove-shaped intermediate piece. The manual control element 2 is therefore not only slideable along the longitudinal axis 12 in the described embodiment example, but is additionally rotatably or pivotably installed around the longitudinal axis 12.

[00118] Figure 16 shows a position of the intermediate part 36 displaced in relation to figure 15.

[00119] Through this displacement, the distance between the housing element 7 of the compensation device 6 and the manual control element 2 is changed.

[00120] As a result, in relation to the situation in figure 15, the closing element 21 is brought closer to the outlet flow opening 18.

[00121] This leads to a short-term closure of the outlet flow opening 18 and thus to a renewed pressure increase in the pressure chamber 14. Since the manual control element 2 is still in its upper position, the valve element 20 is not pressed by the pressure increase towards the valve seat 26, but is only pressed until the outlet flow opening 18 is opened again. Since the closing element 21 cannot continue to follow the valve element 20 due to the position of the control element 2, until it reaches the valve seat 26.

[00122] In this open state, the pressure chamber 14 is relieved again, so that the valve element 20 strives to rise again. Therefore, a floating compensation state arises, in which the input stream 16 is partially opened, so that a reduced flow, compared to figure 15, is placed between the input stream 16 and the output stream 19. It is thus achieved that, in the open position, a reduced maximum distance between the valve seat 26 and the distal end 9 of the control element 4 is obtained compared to figure 15.

[00123] In another example embodiment, the manual control element 2 together with the control element 4 is displaceably arranged by an adjustment device 34, for example, a movement screw 35, along the longitudinal axis 12 to bring the distal end 9 closer to the open position of the valve 3 of the valve seat 26 or to further remove it therefrom.

[00124] A support spring 37 supports in figures 13 to 16 the extension of the control element 2 from the intermediate part 36, which is controlled by the movement thread 35.

[00125] Figures 17 to 19 show another example of embodiment of a valve actuation device 1 according to the invention. Again, components and functional units that are structurally and/or functionally similar or identical to the components or functional units of the preceding exemplary embodiments are referred to by the same reference numerals and will not be described separately again. Therefore, the embodiments in relation to figures 1 to 16 apply in accordance with figures 17 to 19.

[00126] The valve actuation device 1 differs from the preceding embodiment examples in that a cross-sectional area in the outlet flow opening 18, which can be covered by the closing element 21, is enlarged.

[00127] The cross-sectional area in this case has such a size that the closing element 21 is transferred with the control element 4 by an internal pressure in the pressure chamber 14, to the closed position.

[00128] This is possible due to the fact that the cross-sectional area that can be covered by the closing element 21 in the outflow opening 18 is greater than a cross-sectional area of the control element 4 in its outflow of the pressure chamber 14, i.e. in the region of a passage opening 40.

[00129] The cross-sectional area that can be covered in the outlet flow opening 18 is defined by a pilot valve seat 44 that can be closed and released with the closing element 21 and forms with it a pilot valve 46.

[00130] Thus, the replacement element 9 can be dimensioned with a small spring force. This means that the return spring of the manual control element 27 also does not need to be dimensioned with a large spring force. In this way, smooth switching behavior can be achieved.

[00131] The outlet flow opening 18 describes in the direction of flow behind the pilot valve seat 44, a narrowing 45, which may be funnel-shaped, for example, and which leads to a very small internal diameter and/or or internal cross-section of the outlet flow opening 18 along its narrowest point.

[00132] The valve actuation device 1 according to figures 17 to 19 further differs from the preceding embodiment examples in that an outlet flow opening 38 is connected to the outlet flow opening 18. This projects in all switching positions, therefore, even with the valve 3 open, for outflow 19 and prevents a backflow from a main flow path 39 of the open valve 3 next to or in the outflow opening 18.

[00133] The flexible tubing 38 generally has an outer diameter that is smaller than an inner diameter of the valve seat 26 or the outlet flow 19, for example, at most, half the size.

[00134] This is achieved in the example embodiment by the fact that a length 42, with which the valve element 20 projects with the flexible piping 38 to the closed position of the valve 3 in the outlet flow 19, therefore a length 42 between the valve seat 26 and a free end of the flexible piping 38, is at least 1.5 times, preferably at least twice a lifting height 43 of the valve element 20. The lifting height 43 may in this case case, be given by a dimension of the pressure chamber 14 or otherwise, for example by stops for the valve element 20.

[00135] In the case of the valve actuation device 1, it is proposed to form a compensation device 6 between a manual control element 2 and a control element 4, with which a valve 3 is adjustable between an open position and a closed position. closed, with which the control element 4 can be movable against a reset force of a return element 9 relative to the manual control element 2 and movable towards it or away from it, whereby the return element 9 disposed outside the compensation device 6 and/or a piston 8 is disposed in the control element 4 and guided to a housing element 7 of the compensation device 6, alternatively or additionally, a regulation device 34 is formed, with the which control element 4 is removable from the manual control element 2 or movable towards it.
