Abstract

Check valve with a valve housing, on which is formed a valve seat. The valve seat is designed as an oblique face with respect to a flow direction. A shut-off element has at least one sheet-like shut-off tab which is composed of an elastically deformable material and which, in a shut-off position, bears against the valve seat and, in an opening position, is lifted off from the valve seat, in order to allow the passage of fluid. An abutment element is arranged on that side of the shut-off tab which faces away from the valve seat. The shut-off tab can abut against the abutment element in order to limit the amount by which the shut-off tab is lifted off from the valve seat.
