    摘要: A scroll compressor includes scroll compressor bodies with axial tip seals projecting from the respective scroll ribs of fixed and movable scroll compressor bodies. An extended thrust region is provided in surrounding relation to an inner axial tip sealing region to provide for carrying thrust loads in the event that the scroll compressor bodies are forced axially together. Part of the thrust region may carry a tip seal, while another part may be free of a tip seal. This provides for at least a nominal reverse operation capability.

    摘要: A scroll compressor includes a baffle member in a high pressure region of the housing where compressed fluid is stored. The baffle serves to carry and transfer pressure loads away from the central region to an outer periphery region where such loads can be transferred to the outer housing. Deflection, stress and wear on the scroll compressor bodies may be reduced.

    摘要: A refrigeration system has first and second evaporators which may be operated at first and second temperatures. Refrigerant from a lower temperature evaporator may be returned to a compressor suction port. Refrigerant from the higher temperature evaporator may be returned to an intermediate port.

    摘要: A counterweight is attached to a rotating shaft by a slip fit, combined with two axially abutting surfaces to hold the counterweight. The counterweight is preferably held at one face by a ledge formed on the shaft, and at the opposed face by a portion of the motor rotor. Circumferentially spaced abutting surfaces also hold the counterweight to cause the counterweight to rotate with the rotor. The present invention eliminates the need for separately attaching the counterweight to the shaft, and thus reduces both the complexity of assembly, and also the need for precise manufacturing tolerances for the counterweight.
