PRESSURE RELIEF VALVE EMBEDDED IN A MOLDED RUBBER SEAL

摘要

A pressure relief valve (2) includes a valve insert (4) having an opening (14) at a first end (8) and a pathway (12) extending towards the opening (14) from a second end (10) of the valve insert (4). An adjustment member (6) is received within in the opening (14) of the valve insert (4). The valve insert (4) and the adjustment member (6) define a chamber (20) adjacent the pathway (12). The adjustment member (6) includes a throughway. A bearing element (23) is within the chamber and adjacent the pathway (12). A width of the bearing element (23) is larger than a width of the pathway (12). A spring (26) is within the chamber (20) and is under compression and in line with the bearing element (23). A cushioning member (30) surrounds the valve insert 849and allows the flow of pressurized fluid. The spring (26) exerts a force on the bearing element (23) such that the bearing element (23) is biased against the pathway (12) and forms a seal between the chamber (20) and the pathway (12).
