Abstract

A thermally responsive valve assembly having two ports and a valve mechanism interposed between the ports. The assembly employs a bimetallic element assembly including a pair of dish-shaped bimetallic elements of different thermally responsive character. Both bimetallic elements are connected each other so that a snap length of one of the bimetallic elements is cancelled by a snap length of the other bimetallic element at a predetermined temperature. The former bimetallic element is operatively connected to the valve mechanism so that the valve assembly can restore its former position as the temperature is being increased and provide a series of three modes of operation in successive steps on an increasing degree of temperature.
