摘要： A motor-driven scroll type compressor has a motor that includes a rotary shaft and rotates the rotary shaft, a bearing for rotatably supporting front end of the rotary shaft, a fixed scroll member, a movable scroll member driven by rear end of the rotary shaft, compression chambers defined by the movable scroll member and the fixed scroll member and a housing. The rotation of the rotary shaft makes an orbital motion of the movable scroll member around the axis of the rotary shaft and accordingly the compression chambers are moved radially and inwardly thereby to compress the refrigerant gas. The compressor further has a suction chamber communicating with the compression chambers, a discharge chamber, an oil separation chamber separating lubricating oil from the refrigerant gas and communicating with the discharge chamber and a back pressure chamber provided in front of the movable scroll member in the housing and facing to the rear end of the rotary shaft. The back pressure chamber communicates with the oil separation chamber. The rotary shaft includes a first opening at a position adjacent to the front end of the rotary shaft and facing an inner surface of the bearing, a second opening at a position adjacent to the rear end of the rotary shaft and communicating with the back pressure chamber, a communication passage interconnecting the first opening and the second opening and a throttle formed by a clearance between the first opening and the inner surface of the bearing.

摘要： A motor-driven compressor has a compression mechanism, a rotary shaft, an electric motor, a motor drive circuit, a connecting terminal and a housing assembly. The compression mechanism, the electric motor, and the motor drive circuit are disposed along the axial direction of the rotary shaft in the housing assembly having first through third housings. The first housing is used for mounting the electric motor and the compression mechanism. The second housing has a terminal mounting portion for fixing the connecting terminal. The first and second housings have fastening portions at the radially peripheral portion thereof. The third housing is joined to the second housing to form an accommodation space for accommodating the motor drive circuit. The closed casing is formed by fastening the fastening portions of the first and second housings by means of a first bolt and connecting the second housing to the open end of the first housing.
