    Abstract: Grease sealed-type bearings are used for an air-feeding device, the bearings including those such as a bearing for rotatably supporting a shaft, a bearing for rotatably supporting a rotating scroll, and a bearing for rotatably supporting a rotation-restraining member for allowing the rotating scroll to rotate. Sealing members are installed on both sides of rolling bodies of the bearing supporting the rotating scroll, and an inner end portion and an outer end portion of a sealing member are brought to be in contact with an inner ring and an outer ring, respectively.

    Abstract: According to a compressor of the present invention, the compressor further comprises an oil separating mechanism 40 which separates oil from the refrigerant gas discharged from the compressing mechanism 10, the oil separating mechanism 40 includes a cylindrical space 41 in which the refrigerant gas orbits, an inflow portion 42 for flowing the refrigerant gas discharged from the compressing mechanism 10 into the cylindrical space 41, a sending-out port 43 for sending out, from the cylindrical space 41 to the one container space 32, the refrigerant gas from which the oil is separated, and an exhaust port 44 for discharging the separated oil from the cylindrical space 41 into the other container space 32. According to this configuration, efficiency of the electric motor 20 is enhanced, volumetric efficiency is enhanced, and low oil circulation is realized.

    Abstract translation: 根据本发明的压缩机，压缩机还包括将油从压缩机构10排出的制冷剂气体中分离出来的油分离机构40，油分离机构40包括制冷剂气体旋转的圆筒形空间41， 用于使从压缩机构10排出的制冷剂气体流入筒状空间41的流入部42;用于从筒状空间41向一方的容器空间32送出油的制冷剂气体的送出口43 以及用于将分离的油从圆柱形空间41排放到另一个容器空间32中的排气口44.根据该构造，电动机20的效率提高，体积效率提高，并且实现低油循环。
