Double acting pressure relief valve with low pressure seal










Image Number 5 for United States Patent #6305412.

A pressure relief valve that includes a sealing arrangement with a cantilevered seal that prevents fluid from escaping from a system if the differential pressure is only slightly positive yet permits fluid to be released from the system if the internal system pressure exceeds a predetermined pressure differential. In a further embodiment, the pressure relief valve includes a further scaling arrangement with a further cantilevered seal, which is normally closed, but if the internal system pressure should decrease below the external pressure a predetermined amount the second scaling arrangement opens to allow fluid into the system to thereby equalize the pressure and thereby prevent collapse of the system.
