Abstract

See full text

A check valve for arranging between a first pressure chamber, in which a first pressure prevails, and a second pressure chamber in which a second pressure prevails. The valve comprises a valve housing on which a valve seat is formed, and comprises a blocking element which is designed in a blocking position, to close a valve opening in the region of the valve seat, in order to block a connection between the first and the second valve chambers, and is designed in an open position to release the valve opening in order to release the connection between the first and the second valve chambers. The valve seat is configured as an oblique surface, which relative to the flow direction is aligned at an angle which is greater than 15° and less than 80°. The blocking element comprises a planar blocking lobe made from an elastically deformable material which in the blocking position bears against the oblique surface, and in the open position lifts away from the oblique surface in order to release the connection.
