AI Technical Summary

Problems solved by technology

This has the result that such a valve arrangement is complex to manufacture and therefore relatively expensive
The use of solenoid valves as shut-off valves is known, since solenoid valves achieve relatively good tightness at reasonable cost, but do not enable continuous regulation of the flowing medium

Embodiment Construction

[0017] figure 1 A throttle nozzle is shown, which has a housing 1 and a flow channel 2 in the housing 1 , in which a disk-shaped flap 3 is arranged. The valve flap 3 is fixedly connected to a shaft 4 , and the shaft 4 is rotatably supported in the housing 1 . The shaft 4 is driven by an electric motor 5 arranged in the housing 1 , a transmission 6 being connected between the shaft 4 and the electric motor 5 .

[0018] figure 2 Shown in cross-section according to figure 1 part of flow channel 2. The disk-shaped flap 3 is connected in a rotationally fixed manner to the shaft 4 by means of a schematically indicated screw connection 7 . For receiving the shaft 4 the valve flap 3 has a bore 8 in which the shaft 4 is arranged such that the shaft 4 passes through the valve flap 3 at an angle α. In the illustration shown, the valve flap 3 closes off the flow channel 2 . To seal the flow channel 2 , a seal 10 is arranged on the radially surrounding edge 9 of the valve flap 3 . ...

Abstract

The invention relates to a valve device for a fuel cell arrangement in a motor vehicle, having a flow duct (2) running in a housing (1) and a flap (3) arranged in the flow duct (2) for closing the flow duct (2), wherein the flap (3) is fastened on an axle (4), the axle (4) is mounted rotatably in the housing (1), a valve seat is arranged in the flow duct (2) and is in contact with the flap (3) when the latter is in the closed position, and the axle (4) runs through the flap (3) at an angle, and for this purpose the flap (3) has a borehole (8), the openings (13, 14) of which each lead to a flap side. A seal (2) is arranged in the borehole (8) for the axle (4) between the flap (3) and the axle (4).

Description

technical field [0001] The invention relates to a valve arrangement for a fuel cell device in a motor vehicle, the valve arrangement having a flow channel extending in a housing, a valve flap arranged in the flow channel for closing the flow channel, wherein the valve The flap is fastened on the shaft, which is rotatably supported in the housing, and the valve seat is arranged in the flow channel, the valve seat is in contact with the valve flap when the valve flap is in the closed position, and the shaft passes through at an angle. The flap, which for this purpose has bores, the openings of which lead to one side of the flap in each case. Background technique [0002] Such valve arrangements have been known for a long time and are therefore prior art. Due to the flow medium, eg air, the adjusting element must achieve a high degree of tightness when closing the flow channel. Furthermore, the adjusting element should ensure a good adjustment of the flow cross-section of the...
