Definitions
- the invention relates to a valve device for a fuel cell assembly in a motor vehicle with a running in a housing flow channel, the flow ⁇ cross-section influencing flap and the flap antrei ⁇ benden drive, the flap attached to an axle and the axis rotatable in the housing is mounted, arranged in the Strö ⁇ mungskanal valve seat and arranged on a radially peripheral edge of the flap seal, which is in the closed position of the flap in contact with the valve seat, so that the axis penetrates the flap at an angle.
- Ge ⁇ subject of the invention further provides a process for the manufacture ⁇ lung.
- valve devices have long been known and so ⁇ with the prior art. Due to the flowing media, z. As air, the actuators must allow a high tightness when Ver ⁇ close the flow channel. They should also ei ⁇ ne good controllability of the flow cross-section of the Strömungska ⁇ Nals and thus the mass flow of the flowing medium shall afford ⁇ . As a result, such valve devices are complex in construction and therefore relatively expensive. It is known to use solenoid valves as shut-off valves, since the ⁇ se with a corresponding effort a relatively good tightness he ⁇ possible, a continuous control of the flowing medium is not possible.
- valve assemblies as known as a throttle ⁇ flap plate
- the invention is therefore to provide a valve device and a method of the type mentioned above, wel ⁇ che allow a seal of the flow channel with only small Lecka ⁇ ge.
- the required seal should also be simple and inexpensive.
- the first object is characterized in that the seal has an annular base body, that the base body Minim ⁇ least has a recess and that the at least one recess is off with the material of the flap completed dissolved.
- the seal of the device according to the invention consists of egg ⁇ nem annular base body and on the base body ⁇ arranged sealing lip. While the sealing lip is responsible for the actual sealing function, the main body serves to Be ⁇ consolidation of the seal on the flap. The at least one from ⁇ recess in the base body, the arrangement of Klappenma ⁇ TERIAL in this recess, whereby the seal is firmly connected with the flap.
- the main advantage is that the seal is held in this way in the well-defined position and even with changing ⁇ the external conditions their position defined as a sealing seat does not change, thus ensuring a permanent tightness with low leakage rate.
- An odd number of recesses is then advantageous if the recesses symmetrically distributed to be disposed at the periphery of the log ⁇ processing.
- An even number of recesses is advantageous if the recesses are arranged on the two areas, which alswei ⁇ sen the largest angular deflection during rotation of the flap.
- the recesses are circular.
- the number of recesses can be reduced in accordance with another embodiment before ⁇ advantageous for flaps with a larger diameter, if the recesses are designed circular arc.
- the circular arc shape is oriented here advantageously ⁇ on the diameter on which the recesses are arranged in the Grundkör ⁇ by.
- the circular arc shape also has the advantage that the length of the arc creates a larger area than a circle.
- this fact can also be optimized to reduce the arc of the arc since the area required for strength is achieved over the arc length.
- the reduced width of the circular arc has the advantage that it can also reduce the basic body of the seal in radial extent, as a result of which the seal requires less material and is therefore less expensive.
- This effect can be used according to a further advantageous embodiment, even if the recesses have a ge ⁇ rectilinear extent. is rn another embodiment, the inner contour of the sealing circular, so that in particular in a symmetrical distri ⁇ development of the recesses in the body enough space for their arrangement.
- the inner contour of the seal is advantageously formed elliptical, with the major axis coincides with the Pro ⁇ jection of the symmetry axis of the axle in the flap together ⁇ .
- the areas with the largest angular excursions are ⁇ aligned with the minor axis of the elliptical inner contour out ⁇ .
- the elliptical inner contour of the base body has the advantage that where the recesses are arranged, the base body has a greater radial extent, so that ⁇ reaching surface for the arrangement of the recesses is avail ⁇ supply.
- the adhesion of water to the seal is prevented according to a further embodiment in that the seal consists of PTFE (polytetrafluoroethylene).
- a solid and dense composite of seal and flap is achieved according to a further advantageous embodiment in that the flap is an injection molded part and the seal, as far as it is arranged in the flap, is umsprit Zt from the flap.
- the invention further provides a process for Her ⁇ provide a valve device having a a seal aufwei ⁇ send flap, wherein at least one recess aufwei ⁇ send seal is introduced into a mold of an injection molding machine, the mold is closed, an art ⁇ material in the mold is injected, wherein the synthetic ⁇ material fills the mold and thereby fill the recesses in the log ⁇ processing and the the flap is removed from the mold.
- the flap produced by this process ensures by the encapsulation of the seal a particularly secure hold of the seal in the flap.
- the invention is tert erläu ⁇ tert. It show in
- Fig. 4-6 further embodiments of the seal.
- the valve device for a motor vehicle in Figure 1 consists of a housing 1, with a arranged in the housing
- Flow channel 2 for flowing through a fluid In the present case, an air flow is regulated by the valve device.
- an axis 3 is arranged, which is mounted on both sides in the housing 1.
- the first bearing 4 is located on the side of the housing 1 to which a transmission 5 is arranged ⁇ .
- the transmission 5 is the output side connected to the axis 3 and the input side with an electric motor, not shown, which is housed in a separate chamber 6 of the housing 1.
- the second bearing 7 for the axis 3 is located on the opposite side of the gear 5 Strö ⁇ mungskanals 2.
- a flap 8 On the axis 3, a flap 8 is arranged, which has a bore 9 through which the axis 3 extends.
- the flap 8 For attachment to the axis 3, the flap 8 is bolted to the axis 3.
- the flap 8 further has a radially encircling edge 10 on which a seal 11 is arranged. In the illustration shown, the flap 8 is in the closed position ⁇ so that the seal 11 cooperates with the valve seat 12 acting as a region of the flow channel 2 and the flow passage 2 completely closes.
- Figure 2 shows the flow channel of Fig. 1 rotated by 90 °.
- the axis 3 is arranged perpendicular to the image plane and extends slightly upwards into the image plane.
- the radially encircling edge 10 of the flap 8 has in the axial extension of sumption of the gasket 11 has a greater thickness than the radially inward closing at ⁇ area.
- the seal 11 has recesses 13 which are filled with the material of the flap 8 and thereby a secure anchoring of the seal 11 in the flap 8 be ⁇ acts.
- the flap 8 is rotatably connected to the axis 3.
- Fig. 3 shows the seal 11, which consists of a base body 15 and the adjoining sealing lip 16.
- the sealing lip 16 has a circular outer contour, the inner contour 17 of the base body 15 and the like ⁇ tung 11 is formed elliptical.
- the base body 15 has in alignment with the major axis of the ellipsenförmi ⁇ gen inner contour 17 regions 18 a smaller radial Warre- ckung than the areas 19 in alignment with the minor axis.
- the regions 19 are the areas of greatest angular deflection during the pivoting of the flap 8. In these areas are sorted ⁇ wells arranged three recesses 13 through which passes the material of the flap 8, when the seal 11 during herstel ⁇ len of the flap 8 with the Flap material is encapsulated.
- Fig. 4 shows a seal 11, which has a circular réellekon ⁇ structure 17.
- the areas 19, 18 thus have the same radial extent.
- Eight recesses 13 with a circular contour are arranged symmetrically in the base body 15.
- Fig. 6 shows a seal 11 with the same inner contour 7, in which an odd number of recesses 13 are arranged distributed symmetrically on the circumference.
- the seal 11 in Fig. 5 differs from the seal in Fig. 3 in the recesses 13.
- the four circular arc-shaped recesses 13 are arranged analogously to Fig. 3. Due to the larger surface of the recesses 13 in each case only two out ⁇ recesses 13 are each region 19 is provided.
