Abstract: IN PREFERRED FORM, AN AUTOMOTIVE AIR-CONDITIONING SYSTEM HAVING A COMPRESSOR, A CONDENSER, AN EXPANSION VALVE, AN EVAPORATOR AND A FLOW REGULATING THROTTLING VALVE SERIALLY CONNECTED TOGETHER, RESPECTIVELY, AND INCLUDING AN EQUALIZER LINE BETWEEN THE EXPANSION VALVE AND THE THROTTLING VALVE OUTLET. THE EQUALIZER LINE IS NORMALLY BLOCKED BY A THERMALLY ACTUATED VALVE WHICH OPENS WHEN THE COMPRESSOR TEMPERATURE EXCEEDS A PREDETERMINED MAXIMUM. THE OPENING OF THE EQUALIZER LINE TRANSMITS COMPRESSOR INLET PRESSURE TO THE EXPANSION VALVE WHICH OPENS IT TO ALLOW REFRIGERANT TO FLOW THROUGH THE EVAPORATOR AND INTO THE COMPRESSOR FOR COOLING PURPOSES.

Abstract: In preferred form, a four cylinder radial compressor which is operated by an eccentric slider drive mechanism. Two pairs of cylinder bores are radially spaced 90* apart with the center lines of the cylinders lying in a common plane. Opposed pairs of pistons in the bores are linked together with sheet metal links that apply piston preload to an eccentric slider block for high speed continuous operation. The compressor is lubricated by oil that is carried by the refrigerant to the compressor. The refrigerant gas enters the compressor at the rear of the drive shaft and the suction return is diverted into the cylinder housing while the heavier oil enters an aligned hole in the shaft for distribution to the eccentric bearing and eccentric slider of the drive mechanism.
