摘要：A temperature regulator assembly for an automatic temperature controlsystem for the passenger compartment of an automotive vehicle operates by vacuumsignal modulated by a sensor (20) responsive to the difference between an operatorselected temperature which sets the bias of the preload mechanism (22) and thetemperature of air in the passenger compartment of the vehicle which is entrainedthrough opening (48) to flow over a bimetal temperature sensing element (138) of thesensor. A vacuum actuator (14) operated by a modulated vacuum signal produced in thesensor (20) operates an air-blend door via a control rod (40) for controlling the passageof blower driven heated and cooled air into the passenger compartment. Theimprovement lies in the subassembly of bimetal temperature sensing element (138)directly coupled to a vacuum signal modulator valve, the direct coupling of the preloadmechanism to the valve and the direct feedback of the position of the vacuum actuator tothe bimetal sensing element via a spring (160) and lever (162). With this arrangement, thesensor (20) may be pre-calibrated for vacuum control output to the actuator as afunction of the temperature sensed by the element (138) and final calibration may bereadily achieved via the adjustment of the anchorage of the preload spring (22). Byproviding feedback, selective control inputs by the operator are attenuated and better

regulation achieved.
