摘要： In a motor vehicle having a source of vacuum such as the manifold vacuum and a vacuum utilization means, a thermal vacuum switch is interconnected in the conduit between the source and the utilization means for controlling the flow of vacuum according to ambient temperature. The thermal vacuum valve is sealed against vauum leaks between the input and output ports of the valve by the cooperation of a resilient umbrella-shaped dump valve and smooth broadside bimetal disc. Additionally, the structural shape of the valve housing affords the means for thermal bonding of the housing and the cover for preventing vacuum leaks.
