ABSTRACT:
This invention relates to an automatic temperature control system for automobiles and improved components thereof. The control system operates on the proportional stroke principle and comprises an in-car air sensing tube biased with ambient air; a sensor in an aspirator at the end of the tube; a moving pivot operated directly by the output of the sensor; and a feedback valve operated by the moving pivot for driving a vacuum-assist motor, the output stroke of which operates the various electrical and vacuum functions of the heater-air conditioning system.
