Abstract:
A switchable flap valve comprising at least one valve plate pivotably mounted in a housing part so that the valve plate can pivot about a longitudinal axis to open or close a valve opening in said housing part, wherein each valve plate carries a resiliently deformable strip element aligned parallel to the longitudinal axis of the valve plate on one side thereof, said strip element having a lateral face which faces an adjacent housing wall or a similar face of a strip element on a second valve plate, and said strip element forming a hollow channel with the adjacent housing wall or strip element face, a latch mechanism which holds the lateral face of said strip element such that the valve plate is secured in a position in which the valve opening is closed, a pressure generator in communication with at least one end of said hollow channel such that actuation of said pressure generator releases a pressure wave into said hollow channel which deforms the strip element and releases the strip element from the latch mechanism so that the at least one valve plate can pivot to a position in which the valve opening is open.
