Fast response thermostat element

摘要

The thermostat element has an elongated cap (1) forming a chamber housing a material (3) that expands and contracts with changing temperature, displacing a piston (5) at the end of the cap. The side wall of the cap has flats or depressions (15) distributed round the cap, forming a lobed cross-section that almost closes onto an axial rod (9) which has good thermal conduction.
