Description

[0001] The invention relates to a valve device.

[0002] Valve devices with a valve are known, which has a valve body extending along a longitudinal axis. A fluid channel extends through the valve body between a first connection opening and a second connection opening. Furthermore, a valve member is provided, which is accommodated in a receiving chamber of the valve body and can be adjusted between a shut-off position and an open position by means of an actuating device for generating an adjusting movement of the valve member. In the shut-off position, the valve member seals off an overflow section of the fluid channel in a fluid-tight manner and releases it in the open position.

[0003] To guide the adjustment movement, appropriate guide blocks are provided. Known guide blocks define a movement path that includes at least one deflection, e.g., from a rotary movement to a linear movement along the main direction of the valve element. This complex movement sequence prevents rapid adjustment of the valve device. Furthermore, with known valve devices, sufficient space must be taken into account with regard to the overall height to allow for linear movement of the valve element.

[0004] The object of the present invention is therefore to provide a valve device that is easy to handle and space-saving.

[0005] This object is achieved by a valve device having the features of independent claim 1. Further developments of the invention are presented in the subclaims.

[0006] The valve device according to the invention is characterized in that the adjusting movement of the valve member is a rotary movement and the valve member has a blocking section which can be moved out of the overflow section of the fluid channel by the rotary movement in such a way that fluid flows past below the blocking section.

[0007] To achieve the shut-off position, the blocking section is thus moved into the fluid channel by rotating the valve member in the receiving chamber in such a way that the blocking section interrupts the fluidic connection of the fluid channel running from the first connection opening to the second connection opening. The blocking section then dips into the fluid channel in a corresponding manner and closes it completely. The fluid channel and the receiving chamber are therefore congruent in the area of the overflow section. To achieve the open position from the shut-off position, the blocking section is rotated out of the fluid channel by rotating the valve member in the receiving chamber in such a way that the blocking section again releases the fluidic connection of the fluid channel running from the first connection opening to the second connection opening.

[0008] Basically, the valve member is designed so that in the open position fluid can flow past the blocking section. The flow past is a fluid movement in which fluid flows along an outer contour of the valve member without flowing through the valve member, i.e. without the outer contour along which the fluid flows being closed and surrounding the fluid. Below the blocking section means in this context that the fluid channel is arranged below the valve member in the normal operating position of the valve device. The statement below refers only to the arrangement of the components of the valve device therein, but not to an arrangement of the components of the valve device in relation to the surroundings of the valve device. If the valve device is operated lying on its side, for example, this fluid flow takes place with respect to the surroundings next to the blocking section.If the valve device is operated upside down, this fluid flow takes place above the barrier section with respect to the environment.

[0009] Preferably, the valve member is formed in one piece, i.e. the blocking section is formed on the remaining valve member.

[0010] In a further development of the invention, the blocking section is designed to be inclined relative to the longitudinal axis. This ensures that the fluid flowing past the blocking section is vertically displaced, i.e., moves along a vertical axis perpendicular to the longitudinal axis.

[0011] Preferably, an underside of the blocking section extends at an angle in a range of 10° to 60° to the longitudinal axis, preferably in a range of 20° to 50°, particularly preferably in a range of 30° to 40°.

[0012] In a further development of the invention, the overflow section separates a first channel section of the fluid channel assigned to the first connection opening from a second channel section of the fluid channel assigned to the second connection opening, wherein the first channel section opens into the overflow section via a first inner opening and the second channel section opens into the overflow section via a second inner opening, wherein the blocking section projects into the overflow section in such a way that, in the open position, the first inner opening and the second inner opening are released by the blocking section and, in the blocking position, at least one of the inner openings is blocked by the blocking section. In this respect, in the blocking position, the fluid channel is closed by the blocking section at the position of the inner opening blocked by the blocking section.

[0013] Preferably, the first inner opening and the second inner opening are spaced apart from one another with respect to a vertical axis running transversely to the longitudinal axis. Accordingly, the first inner opening and the second inner opening have a height offset. In this way, a side extending along the vertical axis of a blocking section that is designed obliquely with respect to the longitudinal axis can be moved in front of the higher inner opening to reach the shut-off position. If the blocking section is rotated out of the overflow section to reach the open position, the side of the blocking section that covers the higher inner opening in the shut-off position is moved over the lower inner opening without covering the lower inner opening.

[0014] Particularly preferably, a venting channel is provided which passes through the valve member, the venting channel being arranged such that, in the shut-off position, the venting channel and the second internal opening are fluidically connected to one another, such that fluid can escape from the second channel section via the venting channel out of the valve body. Thus, a fluid consumer fluidly connected to the second channel section can be vented via the venting channel. Furthermore, it is preferably provided for this purpose that the second internal opening is arranged above the first internal opening with respect to the vertical axis, and that the venting channel opens into the side of the blocking section which covers the second internal opening in the shut-off position. Thus, in the shut-off position, the aforementioned outlet of the venting channel and the second internal opening at least partially cover one another.

[0015] In a further development of the invention, the fluid channel tapers between the first connection opening and the second connection opening along the longitudinal axis and then widens, with at least one of the inner openings preferably extending over a smaller area than the connection opening assigned to it. In particular, this allows the first inner opening and the second inner opening to be arranged offset in height from one another, while simultaneously keeping the required overall height of the valve device low.

[0016] In a further development of the invention, the actuating device is mechanically connected to the valve member, wherein the actuating device is preferably provided as a manually operated actuating device, wherein furthermore, the actuating device is preferably arranged substantially outside the valve body. This achieves good accessibility and easy adjustability. In particular, the connection between the actuating device and the valve member is designed to be positively and / or non-positively connected.

[0017] Preferably, the actuating device comprises a rotary knob. This allows the rotary movement to be easily transmitted to the valve member.

[0018] In a further development of the invention, a pivot bearing device is provided, with which the valve member is mounted in such a way that it can be adjusted while maintaining a vertical position perpendicular to the longitudinal axis. This prevents vertical movement of the valve member, thus keeping the required installation height low.

[0019] The pivot bearing device preferably has a first sealing means for sealing the fluid channel from the environment. Furthermore, the first sealing means preferably also serves as a plain bearing. This allows the valve member to be securely adjusted while simultaneously ensuring the tightness of the valve device.

[0020] Particularly preferably, the pivot bearing device comprises a second sealing means, in particular for sealing the first channel section from the environment in the shut-off position. Furthermore, in the shut-off position, the first sealing means is preferably arranged below the inner opening concealed by the blocking section, and the second sealing means is arranged above it. In particular, the second sealing means also serves as a plain bearing.

[0021] Particularly preferably, the pivot bearing device comprises a support structure with which the valve member can be supported against the valve body to prevent vertical movement of the valve member. Furthermore, the support structure is preferably arranged in the overflow section and is surrounded by fluid flow in the open position.

[0022] In a further development of the invention, the valve body has a mounting opening arranged in the receiving chamber through which the valve member can be guided. Preferably, a cover is also provided with which the mounting opening can be closed, in particular by a material fit. For this purpose, the mounting opening extends over an area with respect to a plane running parallel to the longitudinal axis that is at least as large as the largest cross-section of the valve member.

[0023] In a further development of the invention, there is a rotational offset of at least 90°, preferably of at least 120°, and particularly preferably of at least 150°, between the open position and the shut-off position. In particular, the valve device is configured to provide the rotational offset both in a first rotational direction and in a second rotational direction opposite to the first rotational direction.

[0024] The invention is explained in more detail below with reference to the accompanying drawings, which show Fig. 1A a valve device in an isometric view obliquely from above, Fig. 1B which in Fig. 1A shown valve device in a side view, Fig. 1C which in the Fig. 1A and Fig. 1B shows a valve device without a rotary knob in a plan view, Fig. 1D which in Fig. 1C shown valve device in a side view, Fig. 1E a detail of the Fig. 1C and Fig. 1D shown valve device, Fig. 2 which in the Fig. 1A and Fig. 1B illustrated valve device with at least one through hole extending through the valve body, Fig. 3A a valve member, Fig. 3B that in Fig. 3A illustrated valve member with at least one first sealing means, Fig. 4A another valve element with a vent channel, Fig. 4B that in Fig. 4A illustrated valve member with at least one first sealing means, Fig. 5A which in the Fig. 1C and Fig. 1D shown valve device with the in the Fig. 3A and Fig. 3B shown valve member in an open position in a side sectional view, Fig. 5B which in Fig. 5A shown valve device in a shut-off position, Fig. 6A which in the Fig. 1C and Fig. 1D shown valve device with the in the Fig. 4A and Fig. 4B shown valve member in an open position in a side sectional view, and Fig. 6B which in Fig. 6A shown valve device in a shut-off position.

[0025] Fig. 1A shows a preferred embodiment of a valve device 100 according to the invention. The valve device 100 has a valve body 110. A fluid channel passes through the valve body 110 between a first connection opening 120 and a second connection opening 122. The valve device 100 further has an actuating device 180, with which an adjusting movement of a valve member 140 (not shown here, see Fig. 3A to 6B). Preferably, the actuating device 180 is arranged on the valve body 110.

[0026] Preferably, the actuating device 180 has a rotary knob 182, which is preferably arranged outside the valve body 110. Using the rotary knob 182, an operator can actuate the actuating device 180 and thus adjust the valve member 140.

[0027] Preferably, the first connection opening 120 and the second connection opening 122 are designed for coupling to a fluid-conducting element, for example, a flexible fluid hose. For this purpose, the first connection opening 120 and / or the second connection opening 122 are designed as quick connectors into which the fluid-conducting element can be inserted for coupling. The first connection opening 120 and / or the second connection opening 122 designed as quick connectors are preferably inserted into the remaining valve body 110.

[0028] The Fig. The valve device 100 shown in Figure 1A comprises a single valve. Several, for example two, such valves can be combined to form a valve device 100 and each connected to one another by a fluid guide element.

[0029] Fig. 1B shows the Fig. 1A in a side view. Preferably, the first connection opening 120 and the second connection opening 122 are each arranged at opposite ends of the valve body 110 with respect to a longitudinal axis 200.

[0030] Preferably, the actuating device 180 is arranged in the center of the valve body 110 with respect to the longitudinal axis 200. Preferably, the actuating device 180 is configured to be rotated about an axis of rotation extending along a vertical axis 202 perpendicular to the longitudinal axis 200.

[0031] Fig. 1C shows the Fig. 1A and Fig. 1B shows a top view of the valve device 100 without the rotary knob 182. Preferably, the valve body 110 further comprises a rotary knob bearing element 184 onto which the rotary knob 182 is placed (see FIG. Fig. 1A and Fig. 1B). Preferably, the rotary knob bearing element 184 is fixedly connected to the valve body 110 or constructed integrally with the valve body 110.

[0032] Fig. 1D shows the Fig. 1C in a side view. Preferably, the rotary knob bearing element 184 has, in particular, a plurality of locking elements on a surface facing the rotary knob 182, which locking elements are preferably tooth-shaped. Furthermore, the rotary knob 182 preferably also has locking elements on a surface facing the rotary knob bearing element 184, which locking elements are preferably congruent with the locking elements of the rotary knob bearing element 184. This achieves a positive connection between the rotary knob 182 and the rotary knob bearing element 184 in the set rotational position of the valve member 140, in particular after a rotational movement has been performed.

[0033] In order to move the rotary knob 182 and thus the valve member 140 out of a set rotational position, the locking elements of the rotary knob bearing element 184 and, if applicable, the locking elements of the rotary knob 182 must be disengaged. Accordingly, rotation of the rotary knob 182 and the valve member 140 coupled thereto is prevented as soon as the locking elements of the rotary knob bearing element 184 engage with the rotary knob 182 or with the locking elements of the rotary knob 182. In order to disengage the rotary knob 182 from the rotary knob bearing element 184, the rotary knob 182 as a whole, or a part of the rotary knob 182 arranged in the rotary knob 182, which part may have the locking elements, is spaced from the valve body 110 and thus from the rotary knob bearing element 184.Preferably, the locking elements of the rotary knob bearing element 184 and / or optionally the locking elements of the rotary knob 182 are designed to be beveled in such a way that by a rotary movement of the rotary knob 182 and after overcoming a resistance caused by the locking elements, the rotary knob 182 or the part of the rotary knob 182 arranged in the rotary knob 182 is automatically spaced from the valve body 110.

[0034] Fig. 1E shows a detail 400 of the Fig. 1C and Fig. 1D. The position of the detail 400 is shown in Fig. 1D. Preferably, the rotary knob bearing element 184 has a first groove 186. Furthermore, the actuating device 180 is preferably configured to engage the rotary knob 182 with the valve member 140 as soon as the rotary knob 182 is engaged with the first groove 186. Preferably, the actuating device 180 is configured such that, when the rotary knob 182 is further spaced from the valve body 110 along the vertical axis 202, the rotary knob 182 is disengaged from the first groove 186 such that the rotary knob 182 is no longer engaged with the valve member 140. If the rotary knob 182 is no longer engaged with the valve member 140, no rotary movement of the valve member 140 can be caused by the actuating device 180.

[0035] Preferably, the rotary knob bearing element 184 has a second groove 187, which is preferably arranged between the first groove 186 and the valve body 110 with respect to the vertical axis 202. Furthermore, the actuating device 180 is preferably configured to engage the rotary knob 182 with the locking elements of the rotary knob bearing element 184 as soon as the rotary knob 182 is engaged with the second groove 187. For this purpose, the rotary knob 182 is to be moved from the first groove 186, preferably along the vertical axis 202, in the direction of the valve body 110.

[0036] Preferably, the rotary knob bearing element 184 has a bead 188 arranged between the first groove 186 and the second groove 187. The bead 188 is configured to resist the movement of the rotary knob 182 along the vertical axis 202. The bead 188 can thus prevent the first rotary knob 182 from being inadvertently disengaged from the first groove 186 or second groove 187.

[0037] Preferably, the first groove 186, optionally the second groove 187 and optionally the bead 188 are formed circumferentially around the rotary knob bearing element 184.

[0038] Fig. 2 shows the Fig. 1A and Fig. 1B, with at least one through-hole 116 extending through the valve body 110. Preferably, the valve device 100 is configured to be attached to another object, e.g., a wall, by means of the through-hole 116. Purely by way of example, the valve device 100 has two through-holes 116.

[0039] Fig. 3A shows a valve member 140. The valve member 140 is received in the valve body 110 in the assembled state of the valve device 100. The valve member 140 preferably has a head portion 146. Furthermore, the valve member 140 preferably has a main portion 147, which in particular borders on the head portion 146. Preferably, a pivot bearing device is provided, with which the valve member 140 is mounted such that it can be pivoted while maintaining a rotational position perpendicular to the longitudinal axis 200 (cf. Fig. 1B to 1D) pronounced vertical position is adjustable.

[0040] The valve member 140 has a blocking portion 142. Preferably, the blocking portion 142 has a bottom side 144 that extends at an angle in a range of 10° to 60° to the longitudinal axis 200 (see Fig. 5A to 6B), preferably in a range of 20° to 50°, particularly preferably in a range of 30° to 40°. Purely by way of example, the underside 144 extends at an angle of 35° to the longitudinal axis 200.

[0041] Preferably, with respect to a plane running parallel to the longitudinal axis 200 and perpendicular to the vertical axis 202, the main portion 147 has a cross-section that is larger than the cross-section of the head portion 146. Furthermore, preferably, with respect to this plane, the main portion 147 has a cross-section that is as large as the cross-section of the locking portion 142.

[0042] Preferably, the pivot bearing device has a first sealing means 164 (cf. Fig. 3B). Furthermore, the first sealing means 164 is preferably arranged in the head portion 146. A first sealing groove 160 is preferably provided in the head portion 146, into which the first sealing means 164 is received. Particularly preferably, the first sealing means 164 and in particular the first sealing groove 160 are arranged in the assembled state of the valve device 100 such that they each run parallel to the longitudinal axis 200 (cf. Fig. 5A to 6B).

[0043] Preferably, the pivot bearing device has a second sealing means 166 (cf. Fig. 3B). Furthermore, the second sealing means 166 is preferably arranged in the main section 147. A second sealing groove 162, into which the second sealing means 166 is received, is preferably provided in the main section 147. Particularly preferably, the second sealing means 166 and in particular the second sealing groove 162 are arranged in the assembled state of the valve device 100 such that they each run obliquely to the longitudinal axis 200, in particular parallel to the underside 144 (cf. Fig. 5A to 6B) .

[0044] Preferably, the valve member 140 has a coupling part 148, which is arranged in particular on the head portion 146. The coupling part 148 is configured to form the connection between the valve member 140 and the actuating device 180 (cf. Fig. 1A to 2) so that a rotary movement initiated via the actuating device 180 can be reliably transmitted to the valve member 140. For this purpose, the coupling part 148 is preferably configured to form a positive connection between the valve member 140 and the actuating device 180. To ensure such a positive connection, the coupling part 148 is designed, for example, as a square. Furthermore, other geometries are possible, for example, those with triangular, pentagonal, hexagonal, or other polygonal bases.

[0045] Preferably, the valve device 100 is configured to provide a coupling between the valve member 140 and the rotary knob 182 via the coupling part 148 when the rotary knob 182 is engaged with the first groove 186 and, if applicable, the second groove 187. Furthermore, the valve device 100 is preferably configured to disengage the coupling part 148 and the rotary knob 182 when—assuming a first groove 186 and, if applicable, a second groove 187 is provided—the rotary knob 182 is neither engaged with the first groove 186 nor, if applicable, engaged with the second groove 187.

[0046] Preferably, the rotary knob bearing element 184 has a recess extending through the rotary knob bearing element 184. The coupling part 148 preferably extends through this recess in the assembled state of the valve device 100. Furthermore, the rotary knob 182 preferably has a recess congruent with the coupling part 148, into which the coupling part 148 is received in the assembled state of the valve device 100. Particularly preferably, the recess in the rotary knob bearing element 184 is circular, and the coupling part 148 is designed such that two opposing outer sides of the coupling part 148 are rounded, at least partially congruent with the recess in the rotary knob bearing element 184. In this way, the coupling part 148 and thus the valve member 140 can be additionally supported on the rotary knob bearing element 184 and thus on the valve body 110, in particular during a rotational movement of the valve member 140.

[0047] The pivot bearing device preferably has a support structure 170 with which the valve member 140 can be supported against the valve body 110. This minimizes the vertical play of the valve member 140. Furthermore, the support structure 170 is preferably rod-shaped. Particularly preferably, the support structure 170 is arranged on the blocking section 142.

[0048] Fig. 3B shows that Fig. 3A with the first sealing means 164 and the second sealing means 166. Preferably, the first sealing groove 160 and the first sealing means 164, as well as optionally the second sealing groove 162 and the second sealing means 166, are designed such that, in the unassembled state of the valve device 100, the first sealing means 164 and optionally the second sealing means 166 project beyond the remaining body of the valve member 140 with respect to the longitudinal axis 200. In this way, it can be achieved that, in the assembled state of the valve device 100, the first sealing means 164 and optionally the second sealing means 166 are pressed against the inside of the receiving chamber 134. Furthermore, the first sealing means 164 and / or optionally the second sealing means 166 are preferably made of a flexible material, in particular of an elastomeric plastic, for example of a silicone rubber.Particularly preferably, the first sealing means 164 and / or optionally the second sealing means 166 are designed as a round cord sealing ring.

[0049] The Fig. 4A and Fig. 4B show a further valve member 140 which, in contrast to the one shown in Fig. 3A and Fig. 3B, the valve member 140 additionally has a venting channel 150. In the Fig. 4B is compared to the valve member 140 shown in Fig. 4A, the first sealing means 164 and the second sealing means 166 are additionally provided (cf. Fig. 3B). The venting channel 150 preferably opens out of the valve member 140 in the main section 147 and, furthermore, preferably also in the head section 146. Particularly preferably, the venting channel 150 also extends through the coupling part 148. In this way, venting can take place in the region of the coupling part 148. Furthermore, the venting channel 150 preferably also extends through the rotary knob 182, so that venting can take place via the rotary knob 182, in particular starting from the main section 147.

[0050] Fig. 5A shows the Fig. 1C and Fig. 1D illustrated valve device 100 with the in the Fig. 3A and Fig. 3B in an open position 300. The valve body 110 has a receiving chamber 134 in which the valve member 140 is received. The fluid channel has an overflow section 136. In the assembled state of the valve device 100, the valve member 140 projects into the overflow section 136 in such a way that in the Fig. 5A, the fluid can flow past the blocking section 142 and through the overflow section 136. Thus, in the open position 300, fluid can flow from the first connection opening 120 through the fluid channel to the second connection opening 122 and vice versa. Preferably, the overflow section 136 is at least partially congruent with the receiving chamber 134.

[0051] In the Fig. In the shut-off position 302 shown in Figure 5B, the valve member 140 seals off the overflow section 136 in a fluid-tight manner. Thus, fluid cannot flow from the first connection opening 120 through the fluid channel to the second connection opening 122.

[0052] The valve device 100 is configured to adjust the valve member 140 by means of a rotational movement between the open position 300 and the shut-off position 302. A rotational movement is a rotation about an axis, in particular about the vertical axis 202 or an axis running parallel to the vertical axis 202, preferably the axis of rotation about which the actuating device 180 is also rotated. As described above, the rotational movement of the valve member 140 is preferably initiated with the rotary knob 182. Preferably, the valve device 100 is designed such that, in the assembled state of the valve device 100, the valve member 140 can be adjusted exclusively by means of a rotational movement. Furthermore, the actuating device 180 is preferably configured to indicate a rotational position of the valve member 140. Purely by way of example, a line marking is provided for this purpose on the rotary knob 182.

Furthermore, the first channel section 130 preferably opens into the overflow section 136 via a first inner opening 124, and the second channel section 132 preferably opens into the overflow section 136 via a second inner opening 126. Particularly preferably, the blocking section 142 projects into the overflow section 136 in such a way that, in the open position 300, the first inner opening 124 and the second inner opening 126 are exposed by the blocking section 142, and in the shut-off position 302, the first inner opening 124 is exposed by the blocking section 142, while the second inner opening 126 is blocked by the blocking section 142.

[0054] Preferably, the blocking section 142 is formed obliquely with respect to the longitudinal axis 200. In this way, at least one intermediate position can be set between the open position 300 and the shut-off position 302. In the intermediate position, the maximum amount of fluid flowing below the blocking section 142 is reduced compared to the open position 300. Preferably, the locking elements of the rotary knob bearing element 184 and, if applicable, the locking elements of the rotary knob 182 are provided corresponding to the possible positions of the valve member 140 from the open position 300 through at least one intermediate position to the shut-off position 302. Particularly preferably, the valve device 100 is designed such that the valve member 140 can be moved into a plurality of intermediate positions. Furthermore, each intermediate position preferably corresponds to a different degree of opening of the valve device 100.

[0055] Preferably, the underside 144 is flat. Alternatively, the underside 144 can be stepped, curved, or arched.

[0056] Preferably, the first internal opening 124 and the second internal opening 126 are spaced apart from each other with respect to the vertical axis 202. Particularly preferably, the second internal opening 126 is arranged closer to the valve member 140 with respect to the vertical axis 202 than the first internal opening 124.

[0057] Preferably, the overflow section 136 is fluid-tightly sealed in the shut-off position 302 by the first sealing means 164 and optionally the second sealing means 166. Furthermore, the second inner opening 126 is preferably arranged so as to penetrate the receiving chamber 134. Preferably, the first inner opening 124 is arranged below the receiving chamber 134. Particularly preferably, in the shut-off position 302, the first inner opening 124 and the overflow section 136 are fluid-tightly connected to one another, while the second inner opening 126 and the overflow section 136 are fluidly separated from one another.

[0058] Preferably, the first sealing means 164 and optionally the second sealing means 166 are at least partially in contact with an inner wall of the receiving chamber 134. Furthermore, the second sealing means 166 and optionally the second sealing groove 162 are preferably arranged obliquely and the second inner opening 126 is designed such that the second sealing means 166 is in the open position 300 (cf. Fig. 5A) as well as in the shut-off position 302 (cf. Fig. 5B) rests against the inner wall of the receiving chamber 134.

[0059] Preferably, the first sealing means 164 and optionally the second sealing means 166 each form a sliding bearing, wherein preferably the first sealing means 164 and optionally the second sealing means 166 are designed to minimize a relative movement between the first sealing means 164 or optionally the second sealing means 166 and the valve member 140.

[0060] In the shut-off position 302, the second sealing means 166 preferably seals off the second channel section 132 in a fluid-tight manner from the overflow section 136 and seals off the overflow section 136 in a fluid-tight manner from an environment surrounding the valve body 110. Starting from the overflow section 136, the environment is fluidically accessible via the first connection opening 120, the second connection opening 122, and the receiving chamber 134, apart from the presence of the first sealing means 164 and, if applicable, the second sealing means 166, and the position of the valve member 140. Furthermore, in the shut-off position 302 and in the open position 300, the second sealing means 166 preferably seals off the first channel section 130 in a fluid-tight manner from the environment accessible via the receiving chamber 134. Particularly preferably, in the open position 300, the second sealing means 166 seals off the second channel section 132 in a fluid-tight manner from the environment accessible via the receiving chamber 134.

[0061] Furthermore, in the shut-off position 302, the first sealing means 164 preferably seals off the second channel section 132 in a fluid-tight manner from the environment accessible via the receiving chamber 134.

[0062] Preferably, the fluid channel extends substantially parallel to the longitudinal axis 200, ie, the first connection opening 120 and the second connection opening 122 are arranged substantially at the same height with respect to the vertical axis 202.

[0063] Preferably, the fluid channel in the first channel section 130 tapers starting from the first connection opening 120 to the first inner opening 124. Furthermore, the fluid channel in the second channel section 132 tapers starting from the second connection opening 122 to the second inner opening 126. Regardless of the fact that the valve member 140 projects into the overflow section 136, it is particularly preferably provided that the fluid channel widens starting from the first inner opening 124 in the direction of the overflow section 136. Regardless of the fact that the valve member 140 projects into the overflow section 136, it is further preferably provided that the fluid channel widens starting from the second inner opening 126 in the direction of the overflow section 136.

[0064] Preferably, the valve body 110 has a mounting opening 112 arranged in the receiving chamber 134. Furthermore, the mounting opening 112 preferably extends, with respect to a plane running parallel to the longitudinal axis 200, over an area that is at least as large as the largest cross-section of the valve member 140, in particular at least as large as the cross-section of the main section 147. In this way, the valve member 140 can be received in the valve body 110 for assembly.

[0065] Preferably, a cover 114 is also provided, with which the mounting opening 112 can be closed, in particular by a material bond. The connection between the cover 114 and the valve body 110 for closing the mounting opening 112 is preferably formed by laser welding. Furthermore, the valve member 140 is preferably supported on the cover 114 by the support structure 170.

[0066] Preferably, the receiving chamber 134 has a first shoulder 138. In the assembled state of the valve device 100, the main portion 147 preferably rests with its end facing the head portion 146 on the first shoulder 138. Furthermore, the first shoulder 138 preferably extends obliquely to the vertical axis 202, purely by way of example, perpendicular to the vertical axis 202.

[0067] Preferably, the receiving chamber 134 has a second shoulder 139. In the assembled state of the valve device 100, the head portion 146 preferably rests with its end facing away from the main portion 147 on the second shoulder 139. Furthermore, the second shoulder 139 preferably extends obliquely to the vertical axis 202, purely by way of example, perpendicular to the vertical axis 202.

[0068] Preferably, the valve member 140 - if a first shoulder 138 and a second shoulder 139 are provided - is supported at least either on the first shoulder 138 or on the second shoulder 139, particularly preferably on the first shoulder 138 and the second shoulder 139.

[0069] Preferably, starting from the overflow section 136 at the first shoulder 138, the cross section of the receiving chamber 134 is reduced such that only the head section 146 can be received in the remaining receiving chamber 134, but not the main section 147.

[0070] Preferably, the first shoulder 138 and optionally the second shoulder 139 limit the displaceability of the valve member 140 along the vertical axis 202 in the direction of the actuating device 180 (cf. Fig. 1A to 2). Furthermore, the cover 114 preferably limits the displaceability of the valve member 140 along the vertical axis 202 in the direction of the mounting opening 112.

[0071] Through the interaction of the first sealing means 164, optionally the second sealing means 166 and optionally the support structure 170 with the inner wall of the receiving chamber 134, optionally the first shoulder 138, optionally the second shoulder 139 and optionally the cover 114, a secure mounting of the valve member 140 in the valve body 110 can be achieved.

[0072] Fig. 6A shows the Fig. 1C and Fig. 1D illustrated valve device 100 with the in the Fig. 4A and Fig. 4B shown valve member 140 in an open position 300 and Fig. 6B this valve device 100 in a shut-off position 302.

[0073] Preferably, the outlet of the venting channel 150 arranged in the main section 147 faces the inner wall of the receiving chamber 134 in the open position 300 (cf. Fig. 6A). Furthermore, the opening of the vent channel 150 arranged in the main section 147 is preferably arranged between the first sealing means 164 and the second sealing means 166. This prevents fluid from escaping from the fluid channel via the vent channel 150 in the open position 300.

[0074] Preferably, the outlet of the venting channel 150 arranged in the main section 147 faces the second internal opening 126 in the shut-off position 302. Thus, fluid present in the second channel section 132 can escape from the fluid channel via the venting channel 150. This is particularly advantageous if the second channel section 132 is fluidically connected to a fluid consumer, for example, to return a fluid consumer configured as a fluid cylinder to its initial position.

[0075] In the Fig. 5B, it is prevented that fluid can pass from the first connection opening 120, in particular from a fluid source coupled to the first connection opening 120, to the second connection opening 122, in particular to a fluid consumer coupled to the second connection opening 122. For this purpose, it is provided that fluid exits from the first channel section 130 via the first inner opening 124 and enters the overflow section 136. Because the blocking section 142 of the valve member 140 covers the second inner opening 126, it is prevented that fluid from the overflow section 136 enters the second channel section 132 via the second inner opening 126. If the valve member 140 is now rotated by means of the actuating device 180, in particular until the position shown in Fig.5A, the blocking section 142 is moved away from the second inner opening 126. This opens the second inner opening 126 and forms a fluidic connection between the first channel section 130 and the second channel section 132 via the overflow section 136.
