CONTROLLED DROOP THERMOSTAT

摘要

Limited droop thermostats in which a bimetal tongue extends from an end of the main ambient temperature-sensing bimetal. The tongue responds to heat emitted by the thermostat switch and acts to compensate for the incidental exposure of the main bimetal to switch heat. In the preferred embodiment the projecting end of the compensating tongue is mechanically fixed and one end of the main bimetal is unitary with and carried by the base of the compensating tongue. Certain features of the invention are present in another embodiment in which the main bimetal element has a conventional supporting pivot at one end and the set-point adjusting end of the main bimetal carries the compensating tongue whose projecting end is movable and actuates the thermostat switch.
