DUAL BIMETAL RELIEF VALVE

摘要

DUAL BIMETAL RELIEF VALVE In an adapter unit for use between an external filter element and fluid reservoir are dual thermostatic pressure relief valves. A body member with a curved recess has ports with opposing valve seats communicating with the recess, and a curved leaf member of approximately threequarters of a full circle is disposed in the recess and is operative as a double valve gate. The leaf member is at least one bimetal strip having a reversal of high expansion and low expansion sides at a preselected point at approximately one-third of its length from an anchor point. Changes in ambient fluid temperature cause a substantially linear displacement between opposing valve seats at the free end of the leaf member.
