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, one in the
- Flow channel is arranged, wherein the flap is fixed to an axle, the axis is rotatably mounted in the housing and in the flow passage a valve seat is arranged, which in
- valve devices have long been known and thus state of the art. Due to the flowing media, as in ⁇ example air, the actuators must allow a high tightness when closing the flow channel. In addition, they should ensure a good controllability of the flow cross-section of the flow channel and thus the mass flow of the flowing medium. This has the consequence that such valve ⁇ devices built consuming and thus are relatively expensive. It is known to use solenoid valves as shut-off valves, since these allow a relatively good tightness with appropriate effort, a continuous control of the flowing medium is not possible. However, the closing of the flow channel has a high importance, since the permissible leak rates are 10 to 20 times smaller than those in conventional intake manifold throttle valves of
- the object of the invention is therefore to provide a valve device of the type mentioned, which allows a continuous control of the medium in a fuel cell assembly he ⁇ allows.
- the object is achieved in that a seal is arranged in the bore for the axis between the flap and the axis.
- Another advantage is that the sealing effect is not generated via the fit pairing of axis and bore and therefore can be manufactured with greater tolerances and thus more cost-effective.
- a further advantageous embodiment is to arrange the seal between the screw hole and the opening of the bore, which leads to the flap side with only one opening. In this way, with the arrangement of only one seal both flow paths can reliably seal.
- the seal is arranged radially on the axis or in the bore for the axis
- Seal is that seals against the respective opposite component.
- the seal is an O-ring.
- the seal In order to ensure a defined seat of the seal, it has been found to be advantageous to arrange the seal in a receptacle, preferably a groove of the axis or the bore.
- a weakening of the components axis or flap through the groove of the seal is avoided according to another advantageous embodiment in that the seal is a bonding of the flap with the axis bonding.
- the advantage of such a seal is that no additional changes to already existing components, such as axle and flap, must be made, so that even existing valve ⁇ devices for these changed conditions can be converted without much effort.
- the seal is a weld connecting the flap with the axis.
- a weld as a seal has the advantage that the density of composite components is generated solely by the axis and the flap and can be disregarded, the chemical Be ⁇ permanence of the adhesive Partners the advantage compared to a bond.
- the drive of the flap takes place in the simplest embodiment by means of an electric motor, the axis via a gear drives.
- an electric motor By the gearbox an exact adjustment of the flap movement is possible.
- FIG. 2 the valve device in section.
- Figure 1 shows a throttle body with a housing 1, located in the housing 1 flow channel 2, in which a disk-shaped flap 3 is arranged.
- the flap 3 is fixedly connected to an axle 4 and the axle 4 is rotatably mounted in the housing 1.
- the axis 4 is driven by a housing 1 arranged in the electric motor 5, wherein between the axle 4 and the electric motor 5, a transmission 6 is interposed.
- FIG. 2 shows a portion of the flow channel 2 of Figure 1 in section.
- the disk-shaped flap 3 is rotatably connected by means of a screw connection 7 shown schematically.
- the flap 3 has a bore 8 in which the axis 4 is arranged, so that the axis 4 penetrates the flap 3 at an angle.
- the flap 3 closes the flow channel 2.
- To seal the flow channel 2 is at the radially peripheral edge
- the fluid prevents the flow around the flap 3.
- the fluid also has the ability to flow through the flap 3 through the bore 8.
- This Mauströmungspfad is formed due to tolerances in the fit between axis 4 and 3 flap.
- the axis 4 has a radially encircling groove 11 in which a seal 12 formed as an O-ring is arranged.
- the seal 12 is arranged closer to the opening 13 than the opening 14 of the bore 8. Since the axis 4 is mounted on the opening 13 with the flap 3, thus resulting in a simpler installation.
- the valve device of Figure 3 differs from the valve device of FIG. 2 in that it can be used for even low leakage rates.
- a second secondary flow path is formed through the bore 15 of the screw connection, through which fluid the flap 3 can flow.
- the flap underside thus has two openings 13, 15, while the flap top has only one opening 14.
