Description

Technical Field

[0001] The present invention relates to a multi-way valve for controlling the flow of liquid and / or gaseous fluid or medium, comprising at least one valve housing, at least one inlet for the inflow of fluid or medium, at least one outlet for the outflow of fluid or medium, in particular at least two outlets, at least one valve disc, at least one drive shaft for adjusting at least one valve disc and at least one actuator for driving at least one drive shaft, wherein at least one valve housing comprises at least one chamber, and at least one valve disc is used to control the flow of fluid or medium in the direction of at least one chamber, in particular at least two chambers. Background Art

[0002] Multiway valves are known in the prior art. They are used to selectively allow a fluid or medium flowing into the multiway valve to flow out through one or more outlets of the multiway valve, thereby distributing the fluid flow, and / or to flow out through only one outlet in a targeted manner. Applications of such multiway valves include in motor vehicles, for example, to control the flow of fluid or medium in a cooling system having a plurality of cooling circuits.

[0003] For example, a multi-way valve in the form of a disk valve is known from EP2917619 B1. The valve has a housing, which has at least one inlet connection and at least one outlet connection as a connection for a liquid and / or gaseous medium, wherein these connections lead to different chambers of the housing, and has at least one valve disc, for example a ceramic valve disc, which is equipped with at least one flow hole and is arranged in a rotatable manner in the housing to connect and separate the chambers from each other in terms of fluid technology by means of at least one flow hole according to its rotational position. In addition, a control shaft is provided, which is connected to the valve disc in a rotationally fixed manner in the housing, wherein the control shaft or the valve disc has at least one radial projection. The housing also has a rotation stop, which is located on the movement path of the radial projection of the control shaft or the valve disc. The housing has a cup-shaped distributor housing and a cover that closes the distributor housing. The cover has a bearing hole, through which the control shaft protrudes outwards with a coupling end, and in which the control shaft is rotatably supported. The control shaft passes through the valve disk via the end opposite the coupling end and is rotatably supported on a sealing disk, in particular a ceramic sealing disk, which bears flat against the valve disk and has at least one second flow opening and is supported in a rotationally fixed manner in the housing.

[0004] A similar multi-way valve is also mentioned in EP2917620 B1. The device comprises a valve having a first housing with a plurality of interfaces for liquid and / or gaseous media, and a drive unit, the drive unit comprising a second housing and a drive device arranged therein, wherein the two housings are arranged at intervals from each other so that there is a thermally insulated air gap between them. The valve has a control shaft, the drive unit has a drive shaft that is operatively / operably connected to the drive device and operatively / operably connected to the control shaft through a coupling device, wherein the coupling device is arranged between the first and second housings, and the coupling device is provided with a splash protection device, which has at least one first protective wall around the periphery of the coupling device. The splash protection device also has at least one second protective wall around the periphery of the coupling device, whose diameter is larger or smaller than the first protective wall, so as to form a labyrinth seal of the coupling device together with the first protective wall. The first protective wall is integrally formed with the first housing, and the second protective wall is integrally formed with the second housing. An axial gap is provided between the free end face of the protective wall and the opposite housing, and the first and / or second housing has a spacer, in particular, designed to be an assembled round cover.

[0005] A multi-way valve is also known from EP2917621B1, which comprises a housing, which has at least one inlet connection and at least one outlet connection as a connection for a liquid and / or gaseous medium, and has at least one rotatably supported valve disc, in particular a ceramic valve disc, which is provided with a first flow hole and is rotatably supported and arranged in the housing to connect and separate these interfaces to each other in terms of fluid technology according to their rotational position. The valve disc is flat against a sealing gasket arranged in a torsionally fixed manner and having at least two second flow holes. An elastically deformable sealing element is arranged between the sealing gasket and the middle bottom of the housing, wherein the sealing element is designed to be disc-shaped and has a third flow hole aligned with the second flow hole. The middle bottom has at least one retaining protrusion inserted into the third flow hole to achieve a shape-fitting anti-rotation of the sealing element. In addition, at least one axial protrusion is arranged in a non-flow hole area on the outside of the middle bottom, which passes through the opening of the sealing element in a shape-fitting manner and is partially located in the receiving groove of the sealing gasket to achieve its anti-rotation.

[0006] All of these multi-way valves have a valve housing and a cover, wherein the respective drive shaft is mounted in a sealing element. Due to this mounting of the drive shaft in the sealing element, leaks may occur and, in the case of wear, problems may occur when the drive shaft rotates. In addition, according to the prior art, the structure of these multi-way valves is relatively complex and therefore relatively costly. Summary of the invention

[0007] Therefore, the object of the present invention is to provide an improved multi-way valve, which, compared with the solutions of the prior art, is used to control the flow of liquid and / or gaseous fluids or media according to the preamble of claim 1, has a simpler structure and lower costs, and can ensure the free rotation of the drive shaft and efficient force transmission.

[0008] With the multi-way valve according to the preamble of claim 1, this object is achieved in that the valve housing is multi-part, wherein a first part of the valve housing comprises at least one inlet, a second part of the valve housing comprises at least one outlet and at least one chamber assigned thereto, and at least one drive shaft is mounted in the valve housing. Further developments of the invention are defined in the dependent claims.

[0009] Therefore, a multi-way valve for controlling the flow of liquid or gaseous fluid or medium is proposed, wherein the valve housing is multi-part, in particular two-part, wherein the first part is equipped with at least one inlet and the second part is equipped with at least one outlet, in particular at least two outlets. Therefore, a valve cover is no longer required, so that at least one actuator can be arranged in the area of ​​the first part of the valve housing. At least one drive shaft passes through the first part of the valve housing with its first end, i.e. the coupling end, and is operatively connected to the actuator that can be arranged or has been arranged on its outside. The drive shaft extends into the second part inside the valve housing with its remaining length. Advantageously, the drive shaft is supported in the second part of the valve housing in the area of ​​its second end, i.e. the end opposite to the first end that can be connected or has been connected to the actuator. Therefore, at least one drive shaft is stably and unobstructedly accommodated and supported in the valve housing of the multi-way valve. By designing the valve housing as a two-part valve housing, wherein the two parts are respectively equipped with a connection in the form of at least one inlet and an outlet, it is no longer necessary to provide a separate, usually large, valve cover. Therefore, the multi-way valve can be designed more simply and space-savingly.

[0010] The first part of the valve housing is provided with at least one inlet, the second part of the valve housing is provided with at least one outlet, in particular at least two outlets, and at least one chamber or at least two chambers assigned thereto. Thus, when at least two chambers are provided, the second part of the valve housing has at least one partition separating the at least two chambers from one another. A receiving opening for supporting the second end of at least one drive shaft can be provided in the region of at least one partition within the second part of the valve housing. Thus, the drive shaft is stably supported in the valve housing or in its second part.

[0011] In order to promote the medium flow in the multi-way valve, at least one drive shaft and at least one valve disc are preferably arranged in the valve housing at an angle of inclination that deviates from 90° relative to the longitudinal axis of at least one inlet and the longitudinal axis of at least two outlets. Compared with the prior art of EP2917619 B1, EP2917620 B1 and EP2917621 B1, this prevents the fluid or medium flow inside the valve housing of the multi-way valve from being deflected by 90°, which would otherwise cause flow losses. By arranging the drive shaft and the valve disc at an angle of inclination that deviates from 90° relative to the longitudinal axis of at least one inlet or the longitudinal axis of at least one outlet, especially the longitudinal axis of at least two outlets of the valve housing, for example at an angle of inclination that deviates from 120° to 150°, especially at an angle of inclination that deviates from 135° relative to the longitudinal axis of the inlet and / or the longitudinal axis of one outlet or the longitudinal axes of these outlets, the fluid or medium flow can be optimized. Therefore, compared with the solutions of the prior art, the flow losses inside the multi-way valve are less. The inclination angle of the longitudinal axis of the at least one inlet and the inclination angle of the longitudinal axis of the at least one outlet may be the same or different, since the longitudinal axis of the at least one inlet and the longitudinal axis of the at least one outlet do not have to be parallel to each other.

[0012] Advantageously, at least one valve disc comprises at least one orifice disc and at least one control disc, wherein at least one control disc is adjustable relative to at least one orifice disc to control the flow of a fluid or medium through at least one orifice disc. Thus, the through hole in the orifice disc, in particular the two openings when two chambers are arranged in the second part of the valve housing, can be partially or completely closed or opened by at least one control disc. Thus, the flow of a fluid or medium from at least one inlet of the first part of the valve housing through the valve housing toward at least one first outlet and / or at least one second outlet can be controlled. Thus, the flow of a fluid or medium can be directed only to at least one first outlet, or only to at least one second outlet, or to at least two outlets. When at least one control disc is in a switching position in the direction of the first and second outlets of the multi-way valve, a symmetrical distribution of the two outlets can be achieved. On the other hand, a proportional distribution of the flow of a fluid or medium between the two outlets can also be achieved. This can be achieved in particular by selecting the design of at least one actuator. For example, it can include a self-locking gear, or can be designed as a BLDC motor, i.e. a brushless DC motor. The actuator is preferably not designed as a stepper motor. Thus, a stepless proportional distribution of a fluid flow or a medium flow between at least two outlets of a multi-way valve can be achieved.

[0013] The at least one orifice disk is further advantageously supported in the valve housing in a rotationally fixed manner. Thus, only the at least one control disk moves relative to the at least one orifice disk, while the orifice disk itself does not move. Thus, the orifice disk and its through-holes can be aligned with the at least two chambers or the inlets of the at least two chambers in the second part of the valve housing of the multi-way valve. Thus, the at least one orifice disk does not rotate relative to the inlets of the at least two chambers of the valve housing, but only the at least one control disk rotates relative to the at least one orifice disk. In this way, the flow in the direction of the at least two outlets of the multi-way valve can be regulated or controlled more accurately.

[0014] It is further advantageous if at least one driver is provided for acting on and driving the at least one control disk. Thus, the at least one driver serves to move the at least one control disk into a desired position. For example, in a top view, the at least one control disk is approximately semicircular and at least two approximately identical through holes are provided in the at least one orifice disk, so that in a control position the control disk completely covers one of the through holes, so that a fluid / medium flow is achieved only through the other through hole of the at least one orifice disk. Thus, the at least one driver can act, for example, on the flat end side of the approximately semicircular control disk in order to be able to move it into the desired position.

[0015] In order to optimize and guide the fluid in the valve housing to flow in at least one outlet, in particular in the direction of at least two outlets, it is further advantageous to set or arrange at least one steering profile on or at the drive shaft. It is particularly advantageous that at least one steering profile is equipped with at least one driver. Through the steering profile, the fluid can be guided to flow from at least one inlet of the first part of the valve housing to at least one outlet, in particular at least two outlets, of the second part without causing the fluid or medium to hit the inner wall of the housing. At least at least one steering profile can be used to ensure that less fluid or medium hits the inner wall of the housing of the valve housing of the multi-way valve. When the inner wall of the housing of the valve housing of the multi-way valve is hit, the continuous fluid flow flowing therethrough is disturbed and the fluid slows down. By setting at least one steering profile, the flow of fluid or medium can be guided or diverted in the valve housing so that it flows therethrough in an optimal flow direction and an optimal flow velocity.

[0016] By providing at least one driver on at least one deflection contour, at least one control disk can be acted on directly, so that no further drivers are required to operate the at least one control disk. Compared with prior art solutions, the component or assembly costs and the assembly effort can thus be reduced.

[0017] It is further advantageous that at least one drive shaft can be equipped with at least one protruding element, in particular at least one crossbar extending in the longitudinal direction of the drive shaft, to transmit the driving force to at least one steering contour of at least one entrainment member. Thus, the drive shaft is engaged with its first end in at least one actuator or the actuator acts on the drive shaft. The driving force applied to the drive shaft by at least one actuator can be transmitted to the steering contour attached to the drive shaft through at least one protruding element outside the drive shaft, and thus also to at least one steering contour of at least one entrainment member. At least one steering contour is arranged on at least one drive shaft and connected to it in a form and force fit and at the same time in a rotationally fixed manner due to at least one protruding element. Thus, the driving force is transmitted from the actuator to the drive shaft, and then from the drive shaft to at least one steering contour and at least one entrainment member that can be connected or connected thereto, and from the element to at least one control disk. At least one protruding element can be designed in particular as at least one crossbar extending in the longitudinal direction of the drive shaft, which crossbar can be inserted into a corresponding receiving portion of at least one steering contour, thereby generating a form-fitting connection between the drive shaft and the steering contour. The at least one deflection profile can have a relatively large height or length extension, so that at least one protruding element on the drive shaft, in particular at least one web extending in the length direction of the drive shaft, can be designed correspondingly longer to achieve a very high force transmission between the at least one drive shaft and the at least one deflection profile. For example, the at least one deflection profile can be equipped with at least two drivers in the form of webs, which act on the flat end face of the at least one control disk and thus achieve a force transmission to the at least one control disk.

[0018] The at least one drive shaft and the at least one steering contour and / or the at least one driver can also be designed as one piece. The one-piece design makes it possible to dispense with the provision of at least one protruding element on the outside of the at least one drive shaft and a corresponding recess in the region of the at least one steering contour. The one-piece design of the at least one drive shaft and the at least one steering contour and / or the at least one driver eliminates the need for an additional form-fitting and / or force-fitting connection between them.

[0019] Advantageously, at least one spring element can be arranged between the at least one deflection contour and the at least one control disk. Such a spring element serves as a pressure spring element or a compensating spring element for compensating tolerances, for holding the control disk and the deflection contour in the desired position, and for bringing the control disk as tightly as possible against the at least one perforated disk in order to avoid leakage flows due to undesired gaps between them.

[0020] In order to enable a predefined switching position of the at least one control disk, at least one end stop can be provided for the at least one driver to prevent its rotational movement in a predefined position. For example, at least one end stop can be provided for the at least one driver in the first part of the valve housing. Such an end stop can be designed, for example, in the form of a protruding lintel, against which the at least one driver strikes, thereby preventing it from rotating further.

[0021] It is further advantageous that at least one flat seal is provided, which is arranged or has been arranged in the second part of the valve housing in a rotationally fixed manner. Such a flat seal preferably has a number of through holes corresponding to the number of through holes of the at least one orifice disk. It is further preferably aligned with the at least one orifice disk and arranged in the second part of the valve housing in a rotationally fixed manner. Thus, the at least one flat seal is aligned with at least two chambers inside the second part of the valve housing, located on the top of the wall surrounding them, in particular on at least one partition between these chambers, wherein the through hole of the flat seal covers the inlet of the chamber inside the second part of the valve housing. At least one orifice disk is placed roughly overlapping with the at least one flat seal and is therefore also arranged in a rotationally fixed manner in the second part of the valve housing. In order to prevent the flat seal from rotating in the second part of the valve housing, protruding lintels can be provided on the upper surface of the wall surrounding the at least two chambers and at least one partition, which lintels are at least partially inserted into the through holes of the flat seal, thereby preventing it from rotating around an axis perpendicular to the plane of the flat seal.

[0022] The valve housing has at least one element protruding toward the interior of the valve housing at least in the region where the at least one orifice disk is positioned, in particular the region where the at least one flat seal and the at least one orifice disk are positioned, and the at least one orifice disk, in particular the at least one flat seal and the at least one orifice disk, can have at least one outer groove corresponding to the at least one protruding element and can engage or engage with each other. The desired anti-rotation function can be provided for the at least one flat seal and the at least one orifice disk by the mutual engagement of the corresponding edge or outer groove with one or more protruding elements. For example, a protruding lintel can be arranged on the inner side of the second part of the valve housing as a protruding element.

[0023] At least one flat seal can have two oppositely arranged flat edge sections, in particular in order to save material. In order to maintain the anti-rotation function of at least one flat seal inside the multi-way valve, in particular, known beams protruding from the upper side of at least two chambers and at least one partition can be used. When a stroke of about 90° is set to switch between the two outlets of the multi-way valve, at least one flat seal can be formed semicircularly and have a flat edge section opposite to the straight outer edge of the semicircle. Similarly, at least one flat seal can or will be formed into a horizontal figure eight. Through these designs, compared with the approximately circular design of at least one flat seal, a smaller pressure difference effective area can be created between the front and rear sides of the control disk, taking into account the pressure difference between the inlet pressure and the output pressure, so that a smaller operating torque or starting torque of the multi-way valve can be achieved when one outlet is completely closed.

[0024] The structure of the multi-way valve is simpler, more economical and easier to install than the multi-way valves in EP2917619 B1, EP2917620 B1 and EP2917621 B1.

[0025] The multi-way valve is suitable for high volume flows. These flows can be, for example, in the range of 350 to 400 liters per minute. Therefore, the multi-way valve is suitable for various applications. For example, the multi-way valve can be used in cooling systems for fuel cells, particularly in the automotive sector.

[0026] Both a flat seal and at least one orifice disk and optionally at least one control disk can be made of at least one ceramic material. The valve housing or two parts of the valve housing and at least one inlet and at least two outlets can be made of plastic material and / or metal or at least one metal alloy.

[0059] Figure 1 and Figure 2 A multi-way valve 1 with a two-part valve housing is shown, wherein the first part 20 of the valve housing 2 is provided with an inlet 22, and the second part 21 of the valve housing 2 is provided with two outlets 23, 24. A receiving device 25 for receiving the actuator 3 is also provided on the outside of the first part 20 of the valve housing 2. The receiving device 25 comprises four cylindrical elements 250, 251, 252, 253 (see also Fig. 9 ), the actuator 3 is supported on these cylindrical elements by means of fastening tabs 31 extending from its housing 30 (see Figure 3 ). For example, the housing 30 of the actuator 3 can be connected to the valve housing 2 of the multi-way valve 1 by fastening bolts or other fixing devices and the columnar elements 250 to 253 of the receiving device 25. The receiving device 25 also includes a cylindrical column 254 arranged between the four columnar elements 250, 251, 252, 253, and the column is connected to the four columnar elements 250 to 253 through reinforcing beams 255, 256, 257, 258 (see Fig. 9 ). The through hole 259 extends through the cylindrical body 254. The drive shaft 4 that can be driven by the actuator 3 can extend through the through hole with its first end 40. Figure 2 and Fig.23 As is particularly clearly shown, the first end 40 of the drive shaft 4 has a contoured design on the outside, so that the drive force can be transmitted to the first end 40 of the drive shaft 4 via the actuator 3. The actuator 3 can be designed, for example, as a BLDC motor, ie a brushless direct current motor.

[0060] like Fig.23 As further specifically shown, the drive shaft 4 has a smooth section 41 near the first end 40, whose outer diameter approximately corresponds to the outer diameter of the first end 40, and a second smooth section 42 protruding relative thereto and therefore having a larger outer diameter near the smooth section 41. This is followed by a disc-shaped protruding section 43, followed by a second disc-shaped protruding section 44 having a smaller outer diameter than the section 43. The section 44 is followed by a relatively long, outer smooth section 45, whose outer diameter remains approximately constant, and finally transitions to the second end 46 of the drive shaft 4. Fig.23 In the exemplary embodiment shown, the second end 46 of the drive shaft 4 has a smaller outer diameter than the section 45. This second end 46 of the drive shaft 4 is mounted in the second part 21 of the valve housing 2.

[0061] On the outside (outside 48) of the smooth section 45 of the drive shaft 4, a protruding crossbar 47 is provided in the longitudinal direction of the drive shaft 4 (indicated by the dotted line L4). The crossbar 47 is used to transmit the driving force transmitted to the drive shaft by the actuator 3 to the deflection profile 5 installed on the outer smooth section 45 of the drive shaft 4. The deflection profile 5 is not only Figure 2 In the Figures 13 to 19 Shown in detail.

[0062] The deflection profile 5 serves as a flow aid for guiding the fluid flow from the inlet 22 through the two-part valve housing 2 in the direction of the two outlets 23, 24 of the multi-way valve 1. The deflection profile 5 therefore has a broad conical shape with semi-conical side surfaces 56. Fig.14 , 15 and 16, which are semicircular in top view and bottom view with a flat end side 50. Along this flat end side 50, the deflection profile 5 has a convex central cylindrical connecting section 51 facing it. From the side view, it consists of a wider lower or first section 52 with a larger outer diameter and an upper or second section 53 with a relatively smaller outer diameter. A through hole 54 passes through the central cylindrical connecting section 51 and is provided with a longitudinal groove 55 in the longitudinal extension direction of the central cylindrical connecting section 51. The protruding crosspiece 47 can be inserted into this longitudinal groove 55 on the outer side 48 of the drive shaft 4, thereby fixing the deflection profile 5 on the drive shaft 4 to prevent rotation.

[0063] like Figures 13 to 19 As shown in the top view and bottom view of the turning profile 5, in particular Figures 17 to 19 In the front view and two side views in FIG. 5 , the deflection profile 5 has not only a semi-conical outer cover surface 56, but also two wing-shaped groove-shaped concave flow surfaces 57, 58 extending near the central cylindrical connecting section 51. Therefore, the fluid flow is guided in the direction of the central cylindrical connecting section 51 or bypasses this part and is guided in the direction of the flat end side 50 of the deflection profile 5. This is in Fig.13 and Fig.14 Along this flat end side 50 of the deflection profile 5, adjacent to the central cylindrical connecting section 51, two beam-shaped driving members 59, 159 are arranged, such as Fig.15 and Fig.16 The two beam-shaped driving members 59, 159 are used to engage with the control disk 6, in particular Figure 2 The control panel 6 shown in FIG. 1 can also be Fig. 20 and Fig. 22 See in detail in order to drive the control panel 6. Fig. 22 As shown, the control disk 6 is semicircular to kidney-shaped in a top view and has a flat end face 60 at least in the middle region, which transitions to an arc-shaped outer edge 63 via rounded outer edges 61, 62. In the region of the flat end face 60, a central protruding section 64 with a through hole 65 is provided. The drive shaft 4 passes through this through hole 65. This can be particularly Fig.24 In the assembly view of the control disk 6, the drive shaft 4 and the steering profile 5, it can be seen that the control disk 6 is located in the steering profile 5. Here, the control disk 6 is located in the steering profile 5. Around the drive shaft 4, between it and the control disk 6 or in its through hole 65, and between the control disk 6 or its arc-shaped outer edge 63 and the surrounding circular drive profile 160 of the steering profile 5, there are respectively gaps to achieve tolerance compensation and flatness compensation.

[0064] The control plate 6 is used to completely or partially cover one or two through holes 70, 71 of the orifice plate 7 so that the flow of fluid or medium through the orifice plate 7 in the region of its first and second through holes 70, 71 can be controlled accordingly. The orifice plate 7 is designed to be flat. It can not only be Figure 2 Seen in Fig. 20 and Fig.21 This can be seen very well in Fig.21 As shown in the figure, the orifice disk 7 is essentially circular in a top view and has a central crossbar 72, which separates the two through holes 70, 71 from each other. The central crossbar 72 is provided with a protruding section 73, which is circular in a top view, approximately in the middle of its longitudinal extension, which section is provided with an inner through hole 74. The drive shaft 4 passes through this through hole. In the extension of the central crossbar 71, the orifice disk 7 is provided with a groove 75, 76 on the edge side. The two grooves 75, 76 are arranged opposite each other and are used to hold the orifice disk in the second part 21 of the valve housing 3 to prevent rotation. For this purpose, the valve housing 2 or its second part 21 has two protruding crossbars 27, 28 arranged on its inner side 26. These can be seen in particular from Figure 8 , as seen in 11 and 12.

[0065] In order to seal the orifice disk 7 relative to the second part 21 of the valve housing 2, a flat seal 8 is provided, which is designed to be approximately the same as the orifice disk 7. In particular, Figure 2 , 8 and 20. Fig. 20As shown, the flat seal 8 is thinner than the orifice disk 7. Like the orifice disk 7, the flat seal 8 has two through holes 80, 81, which are separated by a middle crosspiece 82. The middle crosspiece 82 is also provided with a protruding section 83, which is circular in a top view, in the middle position in its length direction, and the section is provided with a through hole 84, through which the drive shaft 4 can pass. In order to prevent the flat seal 8 from rotating in the second part 21 of the valve housing 2, the flat seal 8 also has two opposite edge grooves 85, 86, which are formed at the edge of the flat seal 8 along the extension direction of the middle crosspiece 82. The two protruding crosspieces 27, 28 on the inner side 26 of the second part 21 of the valve housing 2 also engage in these grooves 85, 86. Therefore, the orifice disk 7 and the flat seal 8 completely overlap in the second part 21 of the valve housing 2. For example, this can also be seen from Figure 5 and Figure 7 In addition, Figure 7 As shown, the orifice disk 7 is pressed against the flat seal 8 on the fastening flange 201 of the part 20 of the valve housing 2 by the wall 206 surrounding and inserted into the second part 21. The wall 206 bears on the orifice disk 7 and thus presses it against the flat seal 8, which is located on the annular step 220 of the part 21.

[0066] like Fig.11 and Fig.12 As shown, two chambers 210, 211 are formed inside the second part 21 of the valve housing 2, which are separated by a partition 212. The partition 212 is provided with a cylindrical receiving section 213 protruding relative to the lateral extension of the partition 212 approximately in the middle of its longitudinal direction, and has an internal receiving opening 214. The second end 46 of the drive shaft 4 is inserted into the internal receiving opening 214 and supported therein. This can be seen from Figure 5 It can be seen in.

[0067] from Figure 5 It can also be seen in the sectional view that in the region of the lower part or first section 52 of the central cylindrical connecting section 51 of the deflection profile 5, a spring element or pressure spring element or balancing spring element 9 is arranged, one end of which is supported on the deflection profile 5 and the other end is supported on the outside of the control disk 6. By arranging the spring element 9 between the deflection profile 5 and the control disk 6, the latter is pressed against the orifice disk 7 and the former is pressed against the second disk-shaped protruding section 44 of the drive shaft 4, so that the control disk 6 can be prevented from being accidentally lifted from the orifice disk 7, thereby preventing an accidental misflow of the liquid and / or gaseous medium or fluid flowing through the valve housing 2 of the multi-way valve 1.

[0068] like Fig.10As further shown, on the inner side 200 of the first part 20 of the valve housing 2, in the region of its fastening flange 201, an end stop 29 for two web-like drivers 59, 159 of the steering profile 5 is provided. The end stop 29 is designed in the form of a web or nose-shaped element protruding on the inner side 200 of the first part 20 of the valve housing 2. Here, the driver 59 or 159 can hit the end stop when the steering profile 5 is rotated by the drive shaft 4, thereby preventing further rotation so that a predefined switching position of the multi-way valve 1 can be achieved. The end stop 29 thus serves as a limiting device for the rotation of the control disk 6, because the two drivers 59, 159 act on the control disk 6 or its flat end side 60 and drive the control disk 6 when the steering profile 5 is rotated by the drive shaft 4. The drive shaft 4 and the steering profile 5 are tightly connected in a form and force fit, and the control disk 6 is only driven by the two drivers 59, 159 when the steering profile 5 is rotated or turned by the drive shaft 4, see Fig.24 .

[0069] exist Figure 5 In the figure, the force flow from the actuator 3 via the drive shaft 4, the deflection profile 5 and the two web-like drivers 59, 159 to the control disk 6 is also shown by arrows P1, P2, P3. Thus, a very good force transmission from the actuator 3 to the control disk 6 is achieved. As an alternative to the illustrated structure of the drive shaft 4 and the deflection profile 5 connected to the drivers 59, 159, these can also be formed in one piece, so that the drive shaft 4 is integrated with the deflection profile 5 or the drivers 59, 159. In this way, in particular, the protruding web 47 can be omitted because it is no longer required.

[0070] like Figure 5 As shown, the drive shaft 4 and the orifice disk 7 are arranged in the valve housing 2 of the multi-way valve 1 with the longitudinal axis L of the inlet 22. 22 or the longitudinal axis L of the two outlets 23, 24 23 , L 24 The inlet 22 extends at an angle of inclination α which deviates from 90°. 22 The relative inclination angle α can be, for example, α=120 to 150°, in particular 135°. Like the perforated disk 7, the two parts 20, 21 of the valve housing 2 are also arranged relative to each other so that their connecting plane E (which extends between their two surrounding fastening flanges 201 and 215) is located at the longitudinal axis L of the inlet 22. 22 or the longitudinal axis L of the two outlets 23, 24 23 , L 24 The orifice plate 7 is arranged approximately perpendicular to the drive shaft 4. The connecting plane E is the plane in which the two parts 20, 21 of the valve housing 2 are connected or fixed to each other. Figure 5 As shown, the longitudinal axis L extending through the inlet 22 and the two outlets 23, 24 22 , L23 and L 24 215 can be arranged approximately parallel to each other. However, in another embodiment, this may also be different. The connecting plane E or the two fastening flanges 201, 215 of the two components 20, 21 can be arranged approximately perpendicular to the longitudinal axis L4 of the drive shaft 4. On the other hand, it is also possible that the connecting plane E of the two fastening flanges 201, 215 or the two fastening flanges extend at an angle different from this to the longitudinal axis L4 of the drive shaft 4. Since the drive shaft 4 and the orifice disk 7 are arranged in the valve housing 2 of the multi-way valve 1 relative to the longitudinal axis L4 of the inlet 22 22 and the longitudinal axis L of the two outlets 23, 24 23 , L 24 The multi-way valve 1 extends at an angle of inclination α deviating from 90°, so that the flow of fluid or medium through the valve housing 2 of the multi-way valve 1 is particularly smooth. Compared with the prior art, no 90° deflection of the flow direction occurs, but due to the approximately parallel arrangement of the inlet 22 and the outlet 23, 24 and the longitudinal axis L of the drive shaft 4 and the orifice disk 7 relative to the inlet 22, the flow direction of the multi-way valve 1 is not changed. 22 and the longitudinal axis L of the two outlets 23, 24 23 , L 24 With an arrangement with an inclination angle α deviating from 90°, the flow is promoted. Even if the longitudinal axes of the inlet and outlet are not parallel to each other, the drive shaft 4 and the orifice disk 7 can be arranged at an angle L to the longitudinal axis L of the inlet 22. 22 or the longitudinal axis L of the two outlets 23, 24 23 , L 24 The tilt angle α is other than 90°, but may be different.

[0071] like Figure 6 , 9, 10, 11 and 12 show particularly clearly that the two fastening flanges 201, 215 of the two parts 20, 21 of the valve housing 2 respectively have a certain number of fastening holes 202, 216, so that the two fastening flanges 201, 215 can be detachably connected together, for example by screws or other fasteners.

[0072] exist Fig.25 and 26 In the embodiment of the multi-way valve 1 shown, the flat seal 8 is not designed to be completely consistent with the orifice disk 7. More precisely, Fig.25 and 26 As shown, the flat seal 8 has two opposite flat edge sections 87, 88. Fig.28 These sections are approximately perpendicular to the middle crossbar 82 of the flat seal 8. Figure 1 In the exemplary embodiment of the flat seal 8 shown, grooves 85, 86 arranged on the outside are provided in the edge region, while Fig.25, 26 and 28, flat edge sections 87, 88 are provided. Therefore, the flat seal 8 can be designed to save material in a particularly good manner. In order to provide an anti-rotation function for the second part 21 of the valve housing 2 in this embodiment variant of the flat seal 8, the flat seal is provided with protruding lintels 221, 222 in the side area relative to the partition 212 between the two chambers 210, 211 and in the area of ​​the wall 223 surrounding the two chambers 210, 211. Therefore, the two protruding lintels 221, 222 surround the area of ​​the two through holes 80, 81 in the flat seal 8, as shown in FIG. Fig.28 As shown. Fig. 27 The projecting crosspieces 221, 222 are clearly visible. The projecting crosspieces 221, 222 are inserted into the through holes 80, 81 of the flat seal 8 after they have been inserted into the second part 21 of the valve housing 2 and thus serve as a guide according to Fig.25 , an anti-rotation device of this design of the flat seal 8 26 or 28.

[0073] exist Figures 30a to 30d It is shown in Fig. 27 The second part 21 of the valve housing 2 in the embodiment of the present invention is shown in which the flat seal 8 is first arranged in the second part 21 of the valve housing 2, then the perforated disk 7, on which the control disk 6 (although not visible in the figure) is located, and on which the deflection contour 5 is located. The drive shaft 4 passes through the corresponding through holes 54, 65, 74 and 84 of the assembly and is supported in the internal receptacle of the opening 214 of the second part 21 of the valve housing 2. Fig.30a In the embodiment, the second chamber 211 is covered by the deflection contour 5 and the control disk 6, so that only a flow in the direction of the first chamber 210 is allowed. Fig.30b In the embodiment, the positions of the deflection contour 5 and the control disk 6 are opposite, and the deflection contour 5 and the control disk 6 cover the outlet to the first chamber 210, thus only allowing the medium to flow in the direction of the second chamber 211. Fig.30c In the embodiment, the positions of the deflection profile 5 and the control disk 6 cover half of the outlet of the control disk 6 and the deflection profile 5, respectively, so that the medium can flow approximately half into the two chambers 210 and 211. Fig.30d In the position of the control disc 6 and the turning profile 5 shown in FIG. 1 , the majority of the medium flows into the first chamber 210 and a smaller portion flows into the second chamber 211. Thus, the control disc 6 and the turning profile 5 can arbitrarily change the flow of the medium into the two chambers 210 and 211, from completely closing the respective chamber 210 or 211 to completely opening the respective chamber 210 or 211.

[0074] Fig.29 and Fig.31 The design of the multi-way valve 1 is shown respectively. In this case, not only the shape of the flat seal 8 is Figure 1 or Fig.28 The orifice plate 7 and the respective first and second chambers 210, 211 or at least the through holes 224, 225 or 227, 228 in these chambers are also different. Fig.29 In the design of the multi-way valve 1 shown, the flat seal 8 presents a horizontal figure eight or Bernoulli lemniscate in a top view. The orifice disk 7 also presents a horizontal figure eight or Bernoulli lemniscate in a top view. In the narrow middle area 226, the orifice disk 7 has two oppositely arranged grooves 77, 78. To prevent rotation, two protruding lintels 27, 28 of the second part 21 of the valve housing 2 can be inserted therein, wherein the two protruding lintels 27, 28 are arranged according to the Fig.29 In the case of the design of the second part 21 of the valve housing 2 of the multi-way valve 1, the second part 21 is designed to be significantly longer than according to Figures 1 to 28 Or 30a to 30d of the embodiment variant. The reason is that the shape of the orifice plate 7 and the flat seal 8 is different from the shape of the orifice plate 7 and the flat seal 8 according to Figure 1 and Fig.25 , the shapes of the corresponding perforated disks 7 and flat seals 8 of 26 and 28 are obviously different.

[0075] according to Fig.29 The shapes of the two through holes 224, 225 and the two chambers 210, 211 in the second part 21 of the valve housing 2 correspond to the two halves of the flat seal 8 formed in a horizontally lying figure eight shape and the orifice disk 7 formed in a horizontally lying figure eight shape. This can also be seen from Fig.29 This is particularly clear in Fig.29 The two through holes 224, 225 in the second part 21 of the valve housing 2 are smaller in size, so that a significantly smaller pressure difference can occur on the pressure-bearing surface between the front side and the rear side of the control disk 6, wherein the inlet pressure P E The output pressure P acts on the upper surface of the control disk 6, which faces the deflection profile 5, while the output pressure P acts on the bottom or rear side of the control disk 6, which faces the orifice disk 7. Fig.29 The through-holes 80, 81 of the flat seal 8 or the through-holes 70, 71 through the perforated disk 7 are significantly smaller than, for example, Figure 1 The design of the orifice plate 7 and the flat seal 8, so that the output pressure P acting on the back of the control plate 6 A It is also significantly smaller than Figure 1 or Fig.25 , 26 and 28 of the multi-way valve 1. Figure 1 and Fig.25 , compared with the design of the multi-way valve 1 shown in 26 or 28, due to the Fig.29In the multi-way valve 1 shown, the pressure difference between the front and rear surface force-bearing areas of the control disk 6 is small, so that in the fully closed state, a smaller starting torque and operating torque are possible at one of the two outlets, i.e., one of the two through holes 224, 225 of the two chambers 210, 211 of the second part 21 of the valve housing 2 of the multi-way valve 1.

[0076] Even according to Fig.31 In a further design of the multi-way valve 1, as according to Fig.29 As in the design of the embodiment, the two chambers 210, 211 can be switched between the two outlets by a 90° stroke of the steering contour 5 and the control disk 6. Fig.31 In the design of , a relatively small area is also provided which is loaded by the pressure difference between the front and rear sides of the control disk 6, which also provides a small operating torque, i.e., a starting torque, for the multi-way valve in a fully closed outlet state, i.e., one of the two through holes 227, 228 of the valve housing 2 of the second part 21. Fig.31 In the design of the second part 21 of the valve housing 2 shown, the two through holes 227, 228 in the two chambers 210, 211 of the second part 21 of the valve housing 2 occupy approximately half the size of the through holes leading to the two chambers 210, 211 of the second part 21 of the valve housing 2, respectively. Figure 1 , Fig.25 and Fig. 27 In order to adapt Fig.31 The shape of the two through holes 227, 228 of the second part 21 of the middle valve housing 2, the flat seal 8 and the orifice plate 7 are also roughly semicircular, so that approximately Fig.25 , 26 and 28 of the corresponding hole plate 7 and the flat seal 8 of the embodiment. The hole plate 7 is provided with an edge beam 79 substantially perpendicular to the middle beam 72. In the hole plate 7 opposite and aligned with the middle beam 72, there is also Fig.31 An outer groove 76 is provided in the second part 21, wherein the protruding lintel 28 of the second part 21 can be inserted into the valve housing 2 to prevent rotation, but Fig.31 The protruding lintel 28 and the protruding lintel 27 are not visible. Fig.31 In the middle, they are diagonally opposite, such as Figure 1 The embodiment shown in Fig.12 as shown in . Fig.31 The flat seal 8 in the embodiment does not have a groove, but is opposite to the edge bridge 89 and approximately perpendicular to the edge bridge 89. Fig.31 The middle crosspiece 82 of the flat seal 8 is provided with a flat edge section 88, such as Fig.25, as shown in the design of the flat seal 8 in 26 or 28. In this way, material can also be saved, thereby reducing the manufacturing cost of the flat seal 8. The flat seal 8 is fixed to prevent rotation by the protruding crosspieces 229, 230, which are inserted into the corresponding through holes 80, 81 in the flat seal 8, as shown in FIG. Fig.31 The protruding lintels 229, 230 extend around respective through holes 227, 228 into the two chambers 210, 211, as shown in FIG. Fig.31 shown.

[0077] In accordance with Fig.31 In the design of the multi-way valve 1, the shape of the control disk 6 is also different from that shown in other figures. Fig.31 In the design scheme, the control disk 6 is designed as a double-wing with two opposite sections. Therefore, each through hole 70 or 71 of the orifice disk 7 can be well covered individually, and the two through holes 80, 81 of the flat seal 8 can also be covered accordingly, so that each through hole 227, 228 in the second part 21 of the valve housing 2 can also be covered.

[0078] In order to be able to operate the control disk 6 of this special shape, the deflection profile 5 has a greater coverage compared to the design of the deflection profile 5 in other variants of the multi-way valve 1. Since the deflection profile 5 spans along its respective flat end sides 66, 67 when operating the control disk 6, but according to Fig.31 In the control panel design of , they are not aligned in a straight line, but at an angle of approximately 60° to each other, so the steering contour 5 is also adjusted accordingly, such as Fig.31 shown, so that it can be Fig.31 The control panel 6 acts on the end sides 66, 67 and operates it.

[0079] like Figure 1 As shown in FIGS. 2, 3, 4, 6, 9, 11, 25, 26, 29 and 31, the two parts 20 and 21 of the valve housing 2 have reinforcing ribs 203, 204 and 217, 218 on the outside, respectively, and these reinforcing ribs extend in a network-like manner on the outside of the first part 20 and the second part 21 of the valve housing 2 of the multi-way valve 1. By providing such reinforcing ribs on the respective outsides 205 and 219 of the two parts 20 and 21 of the valve housing 2 of the multi-way valve 1, the wall thickness of the first and second parts 20 and 21 of the valve housing 2 can be kept relatively small, while still providing sufficient stability for the valve housing 2.

[0080] At the inlet 22 of the valve housing 2, shown as an inlet connection, and at the two outlets 23, 24, likewise shown as outlet connections, pipelines, such as coolant pipelines, can be connected in order to distribute the coolant flow as a medium flow into two cooling circuits in a desired or predeterminable manner via the multi-way valve 1. Thus, the coolant flow can be divided via a plurality of cooling circuits connected to the multi-way valve 1. For example, the multi-way valve 1 can be integrated into the cooling system of a vehicle fuel cell.

[0081] The multi-way valve 1 is designed for the flow of high volume flows. These flows can be, for example, in the range of 350 to 400 liters / minute. Of course, other volume flows can also flow through the multi-way valve 1.

[0082] The control disk 6, the orifice disk 7 and the flat seal 8 can each be made of at least one ceramic material. By using a ceramic material, it can be manufactured within a tight tolerance range and provides wear resistance and abrasion resistance.

[0083] In addition to the embodiment variants of the multi-way valve for controlling the flow of liquid and / or gaseous media or fluids described above and shown in the figures, many other variants can also be formed, in particular any combination of the above features, wherein each multi-way valve comprises at least one valve housing, at least one inlet for the inflow of a fluid or medium, at least one outlet for the outflow of a fluid or medium, at least one valve disk, at least one drive shaft for adjusting at least one valve disk and at least one actuator for driving at least one drive shaft, wherein at least one valve housing comprises at least one chamber, in particular at least two chambers, and at least one valve disk is used to control the flow of a fluid or medium in the direction of at least one chamber, and the valve housing is multi-part, in particular two-part, wherein a first part of the valve housing comprises at least one inlet, and a second part of the valve housing comprises at least one outlet and at least one chamber assigned thereto. In addition, at least one drive shaft is supported in the valve housing.
