Abstract

The check valve (150) consists partly of a valve housing (10) with an inlet (30) and an outlet (40) for a fluid and an inner valve seat (80) and partly a valve body located in the valve housing. The valve body is movable between a closing position in which a sealing head (70) in the valve body locates in a sealed fashion against the inner valve seat, in which a pressure drop over the valve body involves preventing a back flow of water from the outlet to the inlet, and a normally open position in which fluid can flow through the check valve from the inlet to the outlet. The valve body has at least one inner throughflow channel 9136,132) which has an inlet opening issuing downstream from the sealing head closing surface against the valve seat and an outlet opening in the rear foot part (18) of the valve body.
