ABSTRACT:
A pressure relief adapter includes a body and a slideable sleeve positioned in a passageway thereof and cooperating therewith and with O-rings to define a sealed chamber containing ambient air or other gas. The slideable sleeve has an enlarged head at one end. A compression spring in the chamber urges the sleeve toward the end having the enlarged head. Upon introduction of hydraulic fluid under pressure into the passageway and sleeve, the hydraulic fluid acting on the enlarged head urges the sleeve in a direction compressing the spring and reducing the size of the chamber thereby relieving pressure in the fluid flow system in which the adapter is positioned.
