Check valve, particularly mechanically releasable check valve, has housing and valve slide accommodated in housing in linearly movable manner

摘要

The check valve (10) has a housing (20) and a valve slide (30) accommodated in the housing in a linearly movable manner. The housing comprises a load space (21), a tank space (22) and a spring chamber (23). A throttle point (35) with smaller cross-sectional area is provided in a load passage (32) so that the flow resistance from the load space into the spring chamber in an operating state of the check valve is smaller than the flow resistance from the spring chamber into the tank space.
