OVERPRESSURE VALVE IN THE FORM OF A CHECK VALVE

摘要

The invention relates to an overpressure valve (1) which is in the form of a one-way valve or a check valve and which comprises a pot-shaped housing (2) with a base (3) and central opening (4) and which also comprises a valve seat (6) which interacts with a spring-loaded closing body (7). A guide sleeve (9) is inserted with a force fit or form fit into the housing (2) for the purpose of receiving a compression spring (8) which exerts load on the closing body (7), which guide sleeve simultaneously ensures a construction of the overpressure valve (1) which is secured against falling apart.
