摘要: An electrically operated thermally responsive valve having a bimetal operator arm heated by an electrical resistance heater for deflection to move a resilient poppet between an open and closed position on a valve seat for controlling flow to the valve outlet port. The base or active portion of the bimetal arm is formed of a first bimetal material with linear deflection properties up to 700.degree. F. for valve operation. The outboard end or compensator portion of the bimetal arm is formed of a second bimetal material having linear deflection properties up to 300.degree. F. for ambient compensation, but very low deflection properties at valve heater temperatures in the range 300.degree. F.-700.degree. F. for minimizing overcompensation from heating of the outboard portion due to heat transfer from the active portion.
