The invention relates to a valve device for a fuel cell assembly in a motor vehicle, comprising a flow channel (2), which extends in a housing (1), a flap (8), which influences the flow cross-section, a drive, which drives the flap (8), wherein the flap (8) is fastened to a shaft (3) and the shaft (3) is rotatably supported in the housing (1), a valve seat arranged in the flow channel (2), and a seal (11), which is arranged on a radially peripheral edge (10) of the flap (8) and which is in contact with the valve seat in the closed position of the flap (8), the shaft (3) thus penetrating the flap (8) at an angle. The screw (13) has a collar (16), and the shaft (3) has a screw bore (14) having a ledge (15), wherein the collar (16) of the screw (13) comes into contact with the ledge (15) of the shaft (3) in such a way the force transmission occurs from the collar (16) via the ledge (15) when the screw (13) is tightened. |
