ABSTRACT:
A shutoff valve includes a pivotably displaceable flap shaped cutoff part mounted in a flow passageway through a housing. The flap shaped cutoff part is relatively thin so that in the fully open position it does not appreciable reduce the flow passageway cross-section. The cutoff part is pivotably supported at one point in the housing wall and at a diagonally opposite it is supported by a combination of a guide pin and a sliding guide. An actuator located outside the flow passageway is connected to the cutoff part for displacing it between the closed and opened positions. The actuator includes a piston cylinder unit connected to a shifter rod. The shifter rod effects the movement of the guide pin in the sliding guide so that the cutoff part is pivoted about an axis extending transversely of the axis of the flow passageway between the closed and opened positions. By the rectilinear axial movement of the shifter rod the pivotable movement of the cutoff part takes place and the cutoff part is pressed into the closed position into sealed engagement with a valve seat in the housing.
