Abstract: A motor-operated compressor includes a casing having an inner space in which a driving motor, an orbiting scroll and a fixed scroll are accommodated, and a controller provided outside the casing. The casing includes an intake hole formed at a side adjacent to the controller and an exhaust hole formed at a side adjacent to the fixed scroll on the basis of the driving motor. The casing includes a communication passage formed between the casing and a stator of the driving motor, such that a refrigerant introduced into the inner space through the intake hole is introduced into the suction chamber through the driving motor. A back pressure space supporting the orbiting scroll is sealed by oil. The stator has teeth on its inner circumferential surface and protrusions on its outer circumferential surface, each protrusion being located within a width range of each tooth.

Abstract: An electric compressor includes a main housing including a motor chamber. The motor chamber includes a driving motor. The compressor includes a frame fixed to one end of the main housing, a first scroll supported by one side surface of the frame, and a second scroll provided between the frame and the first scroll. The second scroll, supported by the frame, makes an orbiting motion upon receiving a rotational force from the driving motor. The second scroll also forms a compression chamber with the first scroll and a back pressure space with the frame. A rear cover coupled to the main housing forms a discharge space with the first scroll. A back pressure flow channel extends through the first scroll and the frame to guide a refrigerant and oil from the compression chamber to the discharge and back pressure spaces. The compressor also includes a plurality of decompression portions.

Abstract: An electric compressor includes a first scroll and a second scroll engaged with the first scroll and making an orbiting motion to form a pair of two compression chambers with the first scroll. A rotary shaft is eccentrically coupled to the second scroll and is rotatably supported by a bearing member. A frame is fixed to an opposite side of the first scroll from the second scroll with the second scroll being interposed between the frame and the first scroll. The frame includes a bearing support portion, and the bearing member is inserted into and fixed to the bearing support member with an interference fit.
