摘要： A control system for a variable displacement compressor uses a mechanical valve to minimize energy consumption in an air conditioning system. The control system can also provide instantaneous indications to the vehicle controller of air conditioning power consumption to avoid engine loading. Controls are also used to contain oil within the compressor and to minimize its presence downstream of the compressor into the gas cooler and evaporator parts of the system.

摘要： A rear housing for a compressor reduces the operating temperature of the compressor. The compressor generally includes a cylinder block receiving low pressure fluid from the rear housing and providing high pressure fluid back to the rear housing. The rear housing defines a suction chamber and a discharge chamber. The rear housing further defines an isolation chamber positioned between the suction and discharge chambers. In this way, heat transfer between the higher temperature discharge fluid and the lower temperature suction fluid is reduced, thereby reducing the operating temperature of the compressor.

摘要： A swashplate type compressor that includes one or more pistons having an extra support surface for receiving a side load is provided. In a first preferred embodiment of the piston, a rotational restrictor that overlaps the head region is utilized as the extra support surface. In a second preferred embodiment, a support projection, separate from the head region, is utilized as the extra support surface. The extra support surface of the piston of the present invention receives a portion of the side load exerted on the piston, thereby relieving some of stress applied to the head region.

摘要： A compressor for an automotive air conditioning system includes a cylinder head that comprises a mixing chamber, suction chamber and discharge chamber. The cylinder head comprises a first annular wall defining a mixing chamber and a second annular wall disposed about the first annular wall and spaced apart therefrom to define the suction chamber that communicates with the suction ports to the cylinder chambers. The discharge chamber is disposed about the second annular wall and communicates with the discharge ports. Refrigerant flows through the mixing chamber in a swirling or other turbulent pattern and into suction chamber through circumferentially spaced openings. By providing the mixing chamber and isolating the mixing chamber from the suction chamber, pressure pulsation resulting from opening of the suction ports to admit refrigerant is reduced.
