ABSTRACT:
A partitioning sleeve is positioned in the main body of a thermal actuator to form a separate internal liquid reservoir from which fluid may be supplied to the actuator heater. The heater is part of a heater sub-assembly that is sealed in an opening formed in the main body of the actuator so that the coil-type electric resistance heater is accurately positioned for submersion in liquid in the variable volume chamber formed in the main body of the actuator. Moreover, the recycling or cool down time for the thermal actuator is reduced by thermal transfer between an appreciable contacting surface area of an extensible diaphragm that partly forms the actuator chamber and a guide cap that also supports and guides the diaphragm during its extension to enlarge the variable volume chamber.
