Description

[0001] This application is a divisional application of the parent application of the Chinese patent application with application number 202080051263.9, application date July 16, 2020, and invention name “Diverter valve with delay between connection and activation for gaseous or liquid fuels” (PCT international application PCT / EP2020 / 070136 entered the Chinese national stage). Technical Field

[0002] The present invention is a diverter valve for distributing fluid into a tank. The diverter valve has a first fluid interface that can be connected to a fluid input pipeline and a second fluid interface that can be connected to a connecting branch of the tank. The pipeline of the diverter valve is used to transport the fluid from the first fluid interface to the second fluid interface. The main valve is arranged in the pipeline. In addition, the diverter valve includes a coupling device for establishing a connection between the diverter valve and the connecting branch and an actuating device for actuating the coupling device and the main valve. The actuating device includes a handle that can be moved between a closed position and an open position. Background Art

[0003] In particular, such diverter valves are used during so-called pressure filling, wherein a closed system is established between the fluid container and the tank by means of a diverter valve being connected to a connecting branch in an essentially fluid-tight manner. The fluid can then be introduced into the tank with a relative overpressure without the fluid leaking into the environment at the transition between the diverter valve and the connecting branch. Diverter valves of this type are used, for example, for dispensing liquefied petroleum gas (LPG), compressed natural gas (CNG), liquefied natural gas (LNG) or also for dispensing liquefied hydrogen (H2). In particular, for refueling a vehicle, it is desirable that the diverter valve is simple for the user and can be operated in particular with one hand and, in the best case, is used identically to conventional diverter valves for dispensing gasoline or oil, so that no change of habits is required.

[0004] Such a diverter valve is known in principle from the documents EP 1 690 037 B1 or EP 1 883 766 B1. Such a known diverter valve has a lever mechanism connected to a handle, which is designed to actuate a coupling device and a valve. To this end, the previously known lever mechanism comprises a plurality of lever elements, by which forces are applied to the handle in order to actuate the coupling device and the valve substantially simultaneously. The disadvantage of this prior art is that the desired refueling safety cannot always be guaranteed during simultaneous actuation, because this can, for example, lead to the opening of the main valve before the connection to the connecting branch is safely established. In addition, a relatively large expenditure of force is required for actuating the handle, which makes operation difficult. In addition, in this design, the known lever mechanism is a small part, which is therefore easy to wear and has a complex design.

[0005] A pressure filling valve is known from EP 0 039 977, which a user can grasp with one hand at a grip element, wherein an actuating lever is provided, which the user can manipulate with the other hand. The actuating lever is connected to the main valve and the coupling device via a plurality of lever elements connected to each other so that they can rotate. Other diverter valves of the type mentioned at the outset are known from WO 2016 / 168739 and EP 1 006 310. Summary of the invention

[0006] On this basis, the object of the present invention is to provide a diverter valve of the above-mentioned type, which allows easier and more reliable actuation of the main valve and the coupling device. This object is achieved with the features of claim 1. Advantageous embodiments are given in the dependent claims.

[0007] According to the invention, an actuation device is provided which is designed to convert a movement of the handle between the closed position and the open position into a time-shifted actuation of the coupling device and the main valve.

[0008] First, some concepts used within the scope of the present invention are explained. For example, by placing the second fluid interface on the connecting branch, the diverter valve can be connected with the connecting branch of the tank. When connected, a fluid-tight connection is preferably established between the connecting branch and the second fluid interface, wherein the diverter valve is further preferably designed for pressure filling of the tank. The fluid to be dispersed can be, for example, LPG, LNG, CNG and / or H2. The coupling device is used to establish the connection, in particular, the coupling device can be used to interlock the second fluid interface at the connecting branch in order to prevent unintentional loosening after the connection is established.

[0009] The actuating device has a handle. The handle is used to operate the diverter valve and can usually be moved from a closed position to an open position by a user holding the diverter valve in his hand by manual force, in particular by pulling the handle toward the palm with the fingers.

[0010] The closed position of the handle is the position (resting position) of the lever (HEBEL) associated with the closed main valve. The refueling process is usually caused by moving the handle (for example pulling) to the open position, wherein for this, as explained in the scope of the present disclosure, the coupling device and the main valve can be actuated to connect the diverter valve to the connecting branch and open the main valve. However, when the handle is in the open position, the main valve is not forced to open. In particular, there can be an automatic safety cut-off known in principle from the prior art, which is provided for moving the main valve into the closed position independently of the position of the handle. Such a safety cut-off is known, for example, from EP 2 386 520 A1.

[0011] The movement area of ​​the handle has a first handle area according to the invention and a second handle area different therefrom. The designations "first" and "second" should not be used to determine the arrangement of the areas relative to the closed position and the open position.

[0012] The main valve and the coupling device can be actuated by means of the actuating device. The actuation of the main valve can, for example, include opening and / or closing the main valve. The actuation of the coupling device can in particular include establishing and / or releasing a connection between the second fluid interface and the connecting branch, or establishing and / or releasing the above-mentioned interlock. The actuation of the coupling device or the main valve can also be such that an element of the actuating device is moved by movement of the handle so that a subsequent actuation of the coupling device or the main valve can be achieved.

[0013] It is known within the scope of the invention that a time-shifted actuation of the coupling device and the main valve significantly increases user friendliness and refueling safety. On the one hand, it can thereby be ensured that the actuation of the main valve is not initiated until the coupling device has been safely actuated. In particular, it can also be ensured, for example, that the main valve is not opened until the interlock is safely established or that the interlock is not opened until the main valve has been safely closed. It is also known that in a time-shifted actuation, a force applied to the handle at a certain point in time can be converted substantially completely into a corresponding actuation of the coupling device or the main valve, thereby simplifying handling.

[0014] According to the present invention, the actuating device has a connecting joint connected to the handle, which is connected to the connecting device via a first functional connection and to the main valve via a second functional connection, wherein the functional connection for the connecting joint forms a guide portion, thereby causing the connecting joint to rotate around a first pivot axis and / or move in a first direction in a first handle area when the handle is actuated, and thereby causing the connecting joint to move in a second direction and / or rotate around a second pivot axis in a second handle area when the handle is actuated.

[0015] In a preferred embodiment, the coupling joint is connected to the handle on the one hand and is connected to the coupling device and the main valve via two functional connections on the other hand. The concept "functional connection" in principle includes each type of clutch, which is suitable for converting the movement of the coupling joint into the actuation of the coupling device or the main valve. The functional connection is used to transmit the actuation force applied to the handle and the coupling joint to the coupling device or the main valve on the one hand. On the other hand, the functional connection for the coupling joint forms a guide portion, and thus causes the coupling joint to rotate around the first pivot axis or the second pivot axis in the first handle area or in the second handle area when the handle is actuated and / or to move in the first direction or the second direction. This means that the coupling joint rotates around the corresponding pivot axis relative to the diverter valve in the corresponding handle area when the handle is actuated or moves in the corresponding direction relative to the diverter valve, or both rotates around the corresponding axis and moves in the corresponding direction. Here, the first pivot axis is different from the second pivot axis. The first direction is different from the second direction. When the coupling joint is both moved and rotated in the handle area when the handle is actuated, the displacement of the pivot axis is caused due to the displacement. Here, the rotation of the coupling joint is understood in the scope of the invention as a rotation about the first pivot axis as long as the pivot axis does not change its position relative to the coupling joint. Rotation about the other pivot axes only occurs when the position of the pivot axis relative to the coupling joint changes.

[0016] Preferably, the coupling joint can be rotated exactly around the first pivot axis or exactly around the second pivot axis, respectively. In principle, it is also possible within the scope of the present invention to rotate the coupling joint around multiple first pivot axes and / or to shift the coupling joint in multiple first directions in the first handle region during actuation of the handle, wherein it can also be provided that during actuation of the handle, the coupling joint is rotated around multiple second pivot axes and / or to shift the coupling joint in multiple second directions in the second handle region. Here, the set of first pivot axes and the set of second pivot axes are preferably mutually non-intersecting (i.e., mutually different elements). Here, the set of first directions and the set of second directions are also preferably mutually non-intersecting.

[0017] It is known that the above-described use of a coupling joint enables a time-shifted actuation of the coupling device and the main valve in a particularly efficient manner. In particular, this embodiment offers significant advantages over the solutions known from the prior art with a fixed pivot axis. Thus, a force applied to the handle can be converted particularly efficiently, for example firstly into an actuation of the coupling device when passing through the first handle region and into an actuation of the main valve when passing through the second handle region.

[0018] Here, the operative connection can be configured so that the rotation of the coupling joint around the first pivot axis and / or the displacement of the coupling joint in the first direction is at least partially or completely converted into the actuation of the coupling device. In addition, the operative connection can be configured so that the rotation of the coupling joint around the second pivot axis and / or the displacement of the coupling joint in the second direction is at least partially or completely converted into the actuation of the main valve. The movement of the handle in the corresponding handle area can thus be basically completely converted into the corresponding actuation of the coupling device or the main valve, respectively. In contrast, in the application of the conventional lever mechanism known from the prior art, the coupling device and the main valve are actuated basically simultaneously, so that a large actuation force must be consumed.

[0019] The diverter valve can have a component for guiding the coupling joint relative to the housing of the diverter valve. Such a component can be in addition to or instead of a guide part that is operatively connected to form a movement of the coupling joint relative to the housing. Such a component can have a guide pin fixed to the housing, which engages in an elongated hole formed in the coupling joint. This can, for example, enable the coupling joint to be configured to be pivotable about an axis formed by the guide pin or to be displaceable relative to the guide pin in a direction provided by the elongated hole.

[0020] In a preferred embodiment, at least one of the active connections has an intermediate element, which is connected to the connecting joint in an articulated manner. Preferably, the displacement of the intermediate element relative to the diverter valve is caused by the movement of the connecting joint. Additionally or alternatively, the rotation of the intermediate element relative to the diverter valve can also be caused by the movement of the connecting joint. Here, the intermediate element can, for example, be linearly displaced relative to the diverter or be rotatably hinged at the diverter. It has been shown that the guiding of the connecting joint relative to the diverter valve can be achieved in a simple and efficient manner by means of such an intermediate element. On the one hand, the connecting joint can be rotated relative to the intermediate element, so that, for example, the rotatability of the connecting joint around one of the pivot axes can be achieved. At the same time, the displaceability of the connecting joint in one of the directions can be achieved by the displaceability of the intermediate element.

[0021] In a preferred embodiment, two active connections have such an intermediate element. The intermediate element assigned to the first active connection can, in this case, for example, enable the connection joint to be rotatable about a first pivot axis or to be displaceable in a first direction, wherein the second intermediate element can enable the connection joint to be rotatable about a second pivot axis or to be displaceable in a second direction.

[0022] It can be provided that the intermediate element has an actuating rail that is displaceable relative to the diverter valve line and a joint element that articulates the coupling joint to the rail. The joint element can be articulatedly fixed to the rail and / or to the coupling joint.

[0023] In a preferred embodiment, the diverter valve has a device that limits the ability to push and / or rotate the intermediate element. Thus, the intermediate element can only be pushed and / or rotated to the end position by the movement of the coupling joint, wherein, preferably after reaching the end position, the coupling joint is prevented from further rotating around the first pivot axis or the second pivot axis and / or further moving in the first direction or the second direction. The device can be constructed, for example, as a stop surface, at which the intermediate element or an element connected to the intermediate element is stopped, so that after the stop, the intermediate element can no longer move further. Preferably, after the intermediate element reaches the end position, the coupling joint is prevented from further rotating around the first pivot axis or the second pivot axis. In addition or alternatively, it can be proposed that after the intermediate element reaches the end position, the coupling joint is prevented from further moving in the first direction or the second direction. The application of such a device shows an advantageous possibility, realizing the transition between different types of movement of the coupling joint. The device that limits the ability to push can be particularly arranged so that the arrival of the end position of the intermediate element is closely related to the transition of the handle from the first handle area to the second handle area.

[0024] In a preferred embodiment, the intermediate element is connected to a reset element, wherein the reset element promotes or makes it difficult to pivot the coupling element around the first pivot axis or the second pivot axis. Alternatively or additionally, the intermediate element can be connected to a reset element, wherein the reset element promotes or makes it difficult to move the coupling joint in the first direction or in the second direction. The use of reset elements can also be used for this purpose to achieve a transition between different modes of movement of the coupling joint. When, for example, two active connections have intermediate elements loaded by reset elements, the reset force can be adjusted so that when the handle is moved, the first type of movement of the coupling joint first occurs in the first handle area, wherein when the handle transitions to the second handle area, a transition to the second type of movement occurs. One or more reset elements can be constructed in an advantageous embodiment to squeeze the main valve into a closed position of the main valve.

[0025] In one embodiment, the coupling device is configured to establish an automatic interlock between the second fluid interface and the connecting branch when the second fluid interface is pushed in the direction of the connecting branch, wherein the actuating device is preferably configured to first actuate the main valve and then release the interlock between the second fluid interface and the connecting branch when the handle is moved from the open position to the closed position. In this design, the user can connect the diverter valve to the connecting branch without the user having to perform any other actions (hereinafter also referred to as "automatic interlock"). For this purpose, the coupling device can particularly have a radially displaceable interlocking element, which is configured to engage in a recess of the connecting branch.

[0026] In contrast, in the diverter valves known from EP 1 690 037 B1 or EP 1 883 766 B1, the interlock is established between the diverter valve and the connecting branch only by actuating the handle. This makes the operation of the previously known diverter valve difficult, because the user must perform two actions at the same time, namely the correct arrangement of the fluid interface on the connecting branch and the simultaneous actuation of the handle. Although the application of "automatic interlocking" is known in the prior art. However, it has not been possible to actuate a diverter valve with "automatic interlocking" with one hand until now. More precisely, the interlocking must be achieved by the user holding the diverter valve with the aid of a second hand. Only the present invention realizes the one-handed release of the interlocking, by utilizing the time-shifted actuation of the main valve and the coupling device, when the handle moves from the open position to the closed position, the main valve can be closed first and the interlocking can be released in a time-shifted manner.

[0027] It can also be preferably provided that the actuating device is configured to first prepare for release of the interlock and subsequently actuate the main valve when the handle is moved from the closed position to the open position. Since the establishment of the interlock is automatically achieved when the diverter valve is placed in this embodiment, the movement of the handle from the closed position to the open position does not necessarily have to be used to establish the interlock, but can more precisely also be used to prepare for subsequent release. The preparation for release of this interlock can, for example, consist in causing the locking element of the actuating device to lock in the mating locking element of the coupling device, so that when the handle is subsequently moved from the open position to the closed position, the mating locking element can be driven along with the locked element to cause the release of the interlock.

[0028] In a preferred embodiment, the intermediate element thus comprises a locking element which can be locked in a mating locking element of the coupling device. This locking can be achieved within the scope of the actuation of the coupling device and in particular by displacement of the intermediate element. It can thus be achieved that when the intermediate element is subsequently displaced in the opposite direction, the locking element drives the mating locking element. The driving of the mating locking element can likewise be achieved within the scope of the actuation of the coupling device.

[0029] In an alternative embodiment, the coupling device can be placed on the connecting branch by pushing the second fluid interface in the direction of the connecting branch, wherein the actuating device is configured to, after the coupling device is placed on the connecting branch, first establish an interlock between the second fluid interface and the connecting branch and then actuate (in particular open) the main valve when the handle is moved from the closed position to the open position. By the time-shifted actuation of the coupling device and the main valve, a hand force applied entirely by the user can be applied in the first handle area in order to interlock the second fluid interface at the connecting branch. In the second handle area, the hand force applied entirely by the user can then be converted into an actuation of the main valve, in particular an opening of the main valve. The hand force invested by the user to establish the interlock and to open the main valve is therefore significantly reduced compared to the prior art.

[0030] Preferably, the handle and the coupling joint are connected to each other in a torsion-proof manner. Particularly preferably, the handle and the coupling joint are connected to each other in one piece. In a torsion-proof or one-piece connection, the force applied to the handle can be particularly efficiently transmitted to the coupling joint and thus directly and labor-savingly applied to the actuation.

[0031] The invention also provides a split-flow pump having a nozzle according to the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Figure 1The diverter valve according to the invention is shown in a side view before the connection with the connecting branch 15 is established. The diverter valve has a first fluid interface 13 at its rear end, which can be connected to a diverter pipe (not shown), for example. At the front end, the diverter valve comprises a discharge pipe 16 with a second fluid interface 14. The second fluid interface 14 can be connected to the connecting branch 15 by means of a coupling device 30. The diverter valve comprises a housing 18, inside which a pipeline for conveying fluid from the first fluid interface 13 to the second fluid interface 14 extends. A main valve, which cannot be seen in this view, is arranged in the pipeline, via which the flow through the pipeline can be controlled.

[0048] The diverter valve also has an actuating device 17, by means of which the main valve and the coupling device 30 can be actuated. The actuating device 17 also includes a handle 11, which is Figure 1 The actuator 17 is described in more detail below.

[0049] In order to specifically describe the coupling device 30 located at the discharge pipe 16, Figure 2A and Figure 2B An enlarged cross-sectional view of the discharge pipe 16 is shown in FIG. Figure 2A The state is shown before the connection to the connecting branch 15 is established. Figure 2B Shows the status after the connection is established.

[0050] A conduit 32 for conveying a fluid extends inside the discharge pipe 16. The conduit 32 can be closed by a sealing element 33, which establishes a connection with a sliding element 38. The sealing element 33 is Figure 2A The spring 34 is preloaded in the closed position.

[0051] The coupling device 30 comprises a stator 35 which is screwed fixedly to the housing 18. The stator 35 is largely surrounded by an outer sleeve 31 which can be displaced relative to the stator 35 and which is pressed against the front end of the discharge pipe 16 by a spring 36. Recesses are arranged in the outer sleeve 31 and in the stator 35, into which locking elements 37a, 37b can engage. Before the connection is established ( Figure 2A ), the interlocking elements 37a, 37b prevent the sleeve 31 from moving relative to the stator 35.

[0052] When the fluid interface 14 is placed on the connecting branch 15, the front face 15b of the connecting branch 15 contacts the sliding element 38. The sliding element 38 is thereby pushed toward the rear end of the discharge pipe 16. Here, the sealing element 33 that is connected to the sliding element is also pushed and the pipe 32 is released. The connecting branch 15 also has a sealing part 15d with a sealing surface 15c. When the connecting branch 15 is placed, the sealing surface 15c is sealed with the front end of the sealing element 33 (see Figure 2A and Figure 2B ).

[0053] At the same time, the locking element 37a can be displaced inwardly due to the displacement of the sliding element 38, so that the outer sleeve 31 is released and pushed toward the front end of the discharge pipe 16 by the force of the spring 36 relative to the stator 35. When the placement continues, the locking element 37b will enter the recess 15a of the connecting branch 15, so that the connecting branch is locked relative to the stator 35 (see Figure 2B ). The fluid interface 14 is thus securely fixed to the connecting branch 15 , so that the fluid to be dispersed can be safely guided through the pipeline 32 to the connecting branch 15 and the tank connected to the connecting branch.

[0054] Figure 3 After the connection to the connecting branch 15 is established, Figure 1 The diverter valve is shown in the figure. Figure 1 , it can be seen that the outer sleeve 31 is pushed toward the front end of the discharge pipe. By this displacement, the locking element 37b of the outer sleeve 31 is kept in the locked position, in which the connecting branch is locked with the fluid interface 14 (see Figure 2B ).

[0055] Below, according to Figures 3 to 7 The design of the actuating mechanism is described in more detail. Figure 4 A three-dimensional side view of a sub-element of an actuation device according to the invention is shown. Figure 5 and Figure 7 A side view of a diverter valve according to the invention is shown in different states of the actuation device. Fig. 6A and Figure 6B A three-dimensional view of a portion of a diverter valve according to the present invention is shown. The actuating device 17 comprises a handle 11 which is integrally connected to a coupling joint 20. Figure 4 As shown in FIG. 1 , the joint 20 is composed of two symmetrically arranged halves 20 a, 20 b, between which the housing 18 is contained. Figure 3 , Figure 5 6, only half of the joint 20 is shown. For simplicity, only the half of the actuation device that can be seen in the side view will be described below.

[0056] The coupling joint 20 is connected to the coupling device 16 via a first operative connection and to the main valve via a second operative connection.

[0057] The first operative connection comprises a traction hook 21 which is displaceably mounted on the side of the diverter valve. The traction hook 21 is displaceably mounted along the axis of the outlet pipe 16. The coupling joint 20 has a through hole 23, via which the traction hook 21 is connected in an articulated manner to the coupling joint 20. The traction hook 21 represents an intermediate element in the sense of the present invention. The traction hook 21 is mounted at its rear end on a ring 50 which is displaceable along the axis of the outlet pipe 16. The ring 50 is prestressed by a spring 40 which presses the ring together with the traction hook 21 mounted on the ring towards the rear end of the diverter valve. The spring 30 can therefore be regarded as an exemplary restoring element in the sense of the present invention, which is connected to the intermediate element, in the present case to the traction hook 21.

[0058] The second operative connection comprises an articulated lever 22, the first end of which is inserted into a recess 24 of the coupling joint 20. The first end of the articulated lever can roll inside the recess 24 and is thus articulatedly connected to the coupling joint 20 in this way. The articulated lever 22 is articulatedly connected to a valve actuating pin 25 at its other end. The valve actuating pin 25 is mounted in a guide groove 26 located inside the housing 18 so as to be displaceable relative to the housing. The main valve can be opened or closed by displacing the valve actuating pin 25. The main valve is prestressed in the closed position by means of a reset element (not shown). The reset element also presses the valve actuating pin 25 connected to the main valve into its closed position. Figure 3 26 is in the closed position. By moving in the direction of the first fluid connection 13 inside the guide groove 26, the main valve can be opened. The combination of the articulated lever 22 and the valve actuating pin 25 forms an intermediate element in the sense of the present invention. The valve actuating pin 25 can be regarded as a displaceable actuating slide in the sense of the present invention.

[0059] Figure 5 The side view of the diverter valve according to the present invention is shown, in which the handle 11 is moved from the Figure 3 The closed position shown in FIG. 1 is brought to an intermediate position between the closed position and the open position. Figure 3 The closed position shown in Figure 5 The movement range of the handle 11 between the intermediate positions shown in is designated as a first handle range within the meaning of the present invention.

[0060] By moving the handle 11 in the first handle region, the coupling joint 20 is first rotated about the first pivot axis 41 (see Figure 5 ), the first pivot axis being substantially perpendicular to Figure 3 and Figure 5The drawing plane of the coupling joint 20 and the first pivot axis extend approximately through the center point of the recess 24 of the coupling joint 20. At the same time, the coupling joint 20 is guided by the traction hook 21 and the articulated lever 22, so that the position of the pivot axis 41 is displaced during the movement of the handle 11 in the first handle area. In this case, the pivot axis 41 moves in a circle around the valve actuation pin 25. The circular displacement of the pivot axis 41 is caused by the articulated connection of the articulated lever 22 at the valve actuation pin 25. However, the pivot axis 41 remains fixed relative to the coupling joint. The combined rotation and displacement of the coupling joint 20 leads to a displacement of the traction hook in the direction of the front end of the discharge pipe 16. The displacement of the traction hook 21 is carried out against the elastic force of the spring 40.

[0061] exist Fig. 6A and Figure 6B As can be seen in the drawing hook 21, at its front end, there is a bevel 29, a locking element 27 and a stop element 28. In addition, a circumferential projection 39 is arranged at the rear end of the outer sleeve 31. In addition, in the axial direction, the outwardly protruding bevel 51 of the stator 35 is located behind the projection 39 (see FIG. Figure 2B ). During the displacement of the towing hook 21 caused by the rotation of the coupling joint 20, the inclined surface 29 extends externally at the projection 39, so that the front end of the towing hook 21 expands outward. After a certain degree of displacement, the locking element 27 is locked at the rear of the projection 39. In addition, the stop element 28 hits at the rear end of the projection 39, thereby preventing the towing hook 21 from being further displaced toward the front end. Figure 5 , Fig. 6A and Figure 6B The locked state is shown in . Because the pulling hook 21 can no longer be pushed toward the front end, further pushing or rotation of the coupling joint 20 is also prevented.

[0062] Figure 7 The side view of the diverter valve according to the present invention is shown, in which the handle 11 is moved from the Figure 5 The intermediate position shown in is brought to the open position. Figure 5 The intermediate position shown in Figure 7 The movement range of the handle 11 between the open positions shown in represents a second handle range in the sense of the present invention.

[0063] Since the coupling joint 20 is prevented from being further pushed or rotated by the impact of the pulling hook on the stop element 28, the coupling joint 20 is rotated about the second pivot axis 42 when the handle 11 is moved in the second handle area, which is substantially perpendicular to the coupling joint 20. Figure 3 , Figure 5 and Figure 7The drawing plane and the second pivot axis roughly extends through the midpoint of the through hole 23 of the coupling joint 20. Therefore, by actuating the handle 11 in the second handle area, the coupling joint 20 is caused to rotate around the pivot axis 42, which is also converted into a rotation and displacement of the articulated lever 22 and a displacement of the valve actuating pin 25 in the direction of the first fluid interface 13. As a result, the main valve overcomes the force of the reset element of the main valve and moves from the closed position to the open position. The produced fluid can be transported from the liquid interface 13 to the connecting branch connected thereto through the pipeline and the opened main valve via the discharge pipe in this state.

[0064] It can be provided that the handle can be stopped in the open position (not shown here) so that the handle and thus the main valve remain in the open position.

[0065] By releasing any stops and reducing the hand force applied by the user, the handle can be returned from the open position to the closed position after the filling process has ended. Subsequently, the handle first passes through the second handle area and then through the first handle area, respectively in opposite directions. When the handle is moved from the open position to the intermediate position in the second handle area, the coupling joint 20 is first rotated about the second pivot axis 42. Accompanying this movement, the articulated lever 22 rotates and pushes the valve actuating pin 25 toward the front end of the diverter valve, thereby closing the main valve. The above-mentioned movement is caused by the reset element of the main valve, which presses the main valve into the closed position.

[0066] The subsequent movement of the handle from the intermediate position to the closed position (first handle region) is caused by the spring 40, which pulls the pull hook 21 together with the outer sleeve 31 locked therein back to the rear end of the diverter valve, wherein at the same time, the displacement of the coupling joint 20 and the rotation of the coupling joint 20 about the first pivot axis 41 occur in the opposite order to that described above. By pulling back the outer sleeve 31, the locking elements 37a, 37b can be displaced outwards into the recess of the outer sleeve, thereby releasing the connecting branch 15. After the connecting branch is released, the pull hook 21 is still further pulled to the rear, so that the stop 28 of the pull hook 21 reaches the above-mentioned inclined surface 51 of the stator 35 and hits it. In this case, the pull hook 21 expands outwards and thereby releases the locking with the projection 39 of the outer sleeve 31. The outer sleeve 31 can then be freely displaced along the outlet pipe again and can be locked with the connecting branch again as described above in the subsequent connection process.

[0067] Figure 8 An alternative embodiment of the diverter valve according to the invention is shown in a side view. Fig. 9A side cross-sectional view of the discharge pipe of the second embodiment is shown. Elements that have already been described in connection with the first embodiment are provided with the same reference numerals and are not explained again in detail below. Only the differences between the embodiments will be described below.

[0068] Unlike the first embodiment, the second embodiment is not designed to establish an automatic interlock between the second fluid connection 14 and the connection branch 15 when the second fluid connection 14 is pushed in the direction of the connection branch 15. Therefore, in this embodiment, the interlocking occurs only after placement, so that the outer sleeve 31 is moved from the closed position in the direction of the open position by moving the handle in the first handle area. In this embodiment, the pulling hook 21 'is fixedly connected to the outer sleeve 31, which is different from the second embodiment.

[0069] When the fluid interface 14 is placed on the connecting branch 15, the same as in the first embodiment (see Figure 2A and Figure 2B ), the sliding element 38 is pushed back against the restoring force of the spring 52, and the sealing element 33 is moved out of its closed position against the restoring force of the spring 53 (see Fig. 9 ). The locking elements 37a, 37b can then be displaced inwardly so that the outer sleeve can be pushed along the discharge pipe. If the handle is now actuated in the first handle area from the closed position in the direction of the open position, the outer sleeve 31 is pushed forward via the pulling hook 21'. As a result, the fluid interface is locked with the connecting branch (see Fig. 9 ). As in the first embodiment, during the forward displacement of the towing hook 21 ′, a combined displacement and rotation of the coupling joint 20 is achieved by the above-described operative connection and the guide for the coupling joint formed thereby.

[0070] In the locked position, the outer sleeve 31 can no longer be pushed forward, so that in the further actuation of the handle, the coupling joint 20 and thus the pivot axis 42 cannot be pushed further to the front end. If the handle 11 is now moved further in the direction of the open position in the second handle area, the coupling joint 20 is pivoted about the pivot axis 42, the articulated lever 22 is actuated, and the main valve is opened, as described above in conjunction with the first embodiment.

[0071] Fig.10 The diagram shows the state before the interlock is established between the fluid interface 14 and the connecting branch 15. Figure 8. In this view, parts of the articulated lever 22, parts of the handle 11, parts of the coupling joint 20 and parts of the housing 18 can be seen. It can also be seen that a stop 19 is arranged on the housing 18, against which the nose 43 of the coupling joint 20 abuts. If a force is applied to the handle 11 in this state of the actuating device 17 (in which the handle 11 is in the closed position), the stop 19 prevents the movement of the handle 11 due to the connection with the nose 43. This ensures that the main valve cannot be opened as long as the fluid interface 14 is not connected to the connecting branch 15 as required.

[0072] Only by placing the fluid connection 14 on the connecting branch 15 as described above can the locking element 37a be displaced inwardly so that the outer sleeve 31 can be pushed relative to the stator 35 toward the front end of the outlet pipe via the actuating device 17 and the connecting branch 15 can be locked with the stator 35 via the locking element 37b. Only by releasing the outer sleeve 31 can the coupling joint 20 be pivoted past the stop 19 in the first handle area by means of the above-mentioned combined rotation and displacement when the handle 11 is actuated. Figure 8 and Fig. 9 The protection device for preventing the undesired opening of the main valve before establishing the interlock can also be combined in a similar manner. Figures 1 to 7 implementation method to achieve this.

[0073] Fig.11 A further alternative embodiment of the flow diverter valve according to the invention is shown in a side view. Fig.12 Shows Fig.11 3D enlarged view of a portion of an embodiment of the present invention. Elements that have already been described in conjunction with the first and second embodiments are provided with the same reference numerals and will not be described again in detail below. Only the differences from the previous embodiments will be described below.

[0074] Fig.11 and Fig.12 The embodiment of has a handle 11, which is connected to the coupling joint 20' in a rotationally fixed manner. Unlike the coupling joint 20 of the embodiment described above, the coupling joint 20' is designed to contact the rear section 31' of the outer sleeve 31 when the switch lever 11 is actuated. Therefore, the functional connection between the coupling joint 20' and the coupling device 30 is realized by the contact of the front of the coupling joint 20' with the section 31' of the outer sleeve 31, wherein an intermediate element (for example a sliding sleeve) that can reduce friction and / or reduce wear can be arranged in front of the coupling joint 20' and between the section 31'. Unlike the other two embodiments, the functional connection does not have a towing hook.

[0075] The long hole 23' is located at the front end of the connecting joint 20', and the guide pin 60 fixed to the housing 18 is guided through the long hole. The connecting joint 20' can rotate relative to the guide pin 60, and can also be pushed relative to the guide pin 60 (and then relative to the housing 18) in a direction predetermined by the long hole 23'. In this embodiment, the reset element (similar to Fig. 9 The spring 40 in the outer sleeve 31 is pressed toward the rear end of the diverter valve.

[0076] In the transition from the closed position (not shown) to the Fig.11 and Fig.12 When the switch lever is actuated to the open position shown, first of all, a rotation of the connecting joint 20' about the axis 41 occurs (also as in other embodiments). Due to this rotation, the connecting joint 20' is pushed toward the front end of the diverter valve relative to the housing 18. Here, the guide pin moves inside the long hole 23' toward the rear end of the long hole 23'. Due to the forward displacement of the connecting joint 20', the front of the connecting joint 20' is located on the section 31' of the outer sleeve 31. As a result, the outer sleeve 31 overcomes the restoring force of the spring 40 and moves toward the front end of the diverter valve, so that (as in Figure 8 and Fig. 9 In the embodiment of the present invention, interlocking with the connecting branch pipe 15 occurs.

[0077] After locking, the outer sleeve 31 can no longer be moved forward further. Therefore, during further actuation of the switch lever 11, a rotation of the coupling joint 20' occurs about the axis of the guide pin 60. This rotation also leads to an actuation (rotation and displacement) of the articulated lever 22 as already described in connection with other embodiments and to a displacement of the valve actuation pin 25 in the direction of the first fluid connection 13 and to the opening of the main valve.

[0078] During the closing movement of the handle, the above-described actuation process takes place in reverse order, so that in this respect there are no further differences from the embodiments already described above.
