ELECTRO-THERMAL LINEAR ACTUATOR WITH INTERNAL RESERVOIR

摘要

In re application of Richard G. Huebscher; Subjects, Ronald S.; Birli Joseph A> For "ELECTRO-THERMAL LINEAR ACTUATOR WITH INTERNAL RESERVOIR" 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 aub-assembly that is sealed in an opening formed in the main body of the actuator so that the coil-type electric resistance heater if 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 acutator is reduced by thermal transfer between an sub-assembly 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 extendsion to enlarge the variable volume chamber.
