  • Patent number: 10107288
    Abstract: A housing for a scroll compressor and a scroll compressor are provided. The housing includes: a cannular central part; a center hole disposed at the cannular central part; a plurality of arms substantially extending radially from the cannular central part, the plurality of arms being used to be connected with a fixed scroll of the scroll compressor; and a thrust bearing surface disposed on a first side of the cannular central part in an axial direction, the thrust bearing surface being used to support an orbiting scroll. The orbiting scroll is supported with low friction, the motor supporting shell tube and the fixed scroll are connected with better alignment, and materials and machining costs are saved. In addition, the housing can provide better support for a scroll set, thereby achieving better performance.

  • Publication number: 20150354567
    Abstract: A scroll compressor includes a shell; an orbiting scroll; a fixed scroll, the orbiting scroll and the fixed scroll forming a compression component; a housing, configured to support the fixed scroll, with a gas passage throughout the housing and leading to the compression component; a motor below the housing, including: a rotor; a stator; a drive shaft connected with the orbiting scroll; a motor supporting shell tube, wherein the tube is in the shell, an upper end of the tube is connected with the housing, and the rotor and the stator are in the tube; a first suction inlet, at a lower portion of the shell; a second suction inlet, at a lower portion of the motor tube; and a first passage formed by a gap between the shell and the tube, gas from the first suction inlet entering the compression component through the gas passage along the first passage.

  • Patent number: 8328566
    Abstract: A sealed compressor has an electric motor and a compressor pump unit to be driven by the electric motor. Power is supplied to the electric motor by a terminal plug received within a housing, which communicates electricity through an electric connection and into a shell housing the compressor. A cable is connected to the terminal plug at a location at least partially outwardly of the housing. The cable includes a ground wire and ground connector, which is connected to a ground pin associated with one of the housing and the shell. The cable has a head connected to connections associated with the housing. A shield extends over a ground connection between the cable and the ground pin. A cable and cable head as mentioned above are also disclosed and claimed.
