Abstract
A pinch valve includes a clamping jaw () which displaces perpendicularly to an axial direction and forms a mouth () that receives a flexible tube () that extends in the axial direction, and an abutment () which is opposite the clamping jaw in the jaw displacement direction. The clamping jaw and the abutment are disposed relative to one another such that the tube is pinched by the advancing clamping jaw against the abutment. The clamping jaw has a displaceable support element () and two claws () located opposite one another and engaging around the tube at least in some regions. The claws are articulated on the support element by the respective rear ends thereof such as to pivot about pivot pins oriented parallel to the axial direction, whereby the mouth opens as the clamping jaw advances and closes as the clamping jaw retracts.
