Abstract
An improved, dual function, thermal valve assembly has two passages and two valve mechanisms disposed in the passages, respectively. The assembly employs two thermally responsive actuating members which are actuatable to provide the dual functions in successive steps upon an increasing degree of temperature. The assembly is characterized by provision of a cavity to contain in isolation the thermally responsive actuating members from the passages to thereby avoid a tendency of thermal influence from the air flow passing through the passage.
