Electrically-driven compressor

An inverter assembly includes a substrate, a capacitor assembly and a coil, a varistor and a base. The base fixes and supports thereto the substrate, the capacitor assembly, the coil, and the varistor, and is detachably fixed together to a first housing with screws.

Electric compressor

An electric compressor includes an electric motor, a compression mechanism driven by the electric motor, and a housing for accommodating the electric motor and the compression mechanism. The housing is formed such that the stator is fitted thereto. The housing has a plurality of thick portions and a plurality of thin portions. The center of the thickness of each thick portion is located outside of the center of the thickness of each thin portion with respect to a radial direction of the housing. As a result, even if the housing is deformed, the fixation of the stator to the housing is reliably maintained. Further, the weight of the electric compressor is reduced.

A compressor housing defines a motor accommodating chamber. The pressure in the motor accommodating chamber is equal to the pressure in a suction chamber. A first reservoir chamber is located in a discharge chamber. A second reservoir chamber is defined about the discharge chamber. A communicating passage connects the first reservoir chamber with the second reservoir chamber. A restrictor is located in the communicating passage. An oil return passage connects the second reservoir chamber with the suction chamber. A connecting passage connects the motor accommodating chamber with the suction chamber. Therefore, leakage of electricity is prevented.

A sealed type motor-driven compressor includes a cylindrical motor housing and an annular stator core fastened to the interior of the motor housing. A method of assembling the compressor includes fastening the stator core to the motor housing by mechanically deforming at least one of the motor housing and the stator core. It is thus possible to set the fastening interference between the motor housing and the stator core to a sufficiently great level for suppressing loosening of the stator core with respect to the motor housing, which may otherwise be caused by a relatively high pressure produced by refrigerant gas.

A motor accommodating chamber accommodates an electric motor such that a rotation axis of the motor is substantially horizontal. The pressure in the motor accommodating chamber is equal to the pressure in a suction chamber. A connecting passage connects a bottom portion of the motor accommodating chamber with the suction chamber. Therefore, mixture of liquids having a lowered insulating property is prevented from staying in a motor accommodating chamber.

A scroll type compressor includes a housing defining a discharge pressure region, a fixed scroll member having a fixed base plate and a fixed scroll wall, a movable scroll member having a movable base plate and a movable scroll wall, a fixed wall slidably supporting the movable scroll member, a back pressure chamber defined on a back surface side of the movable base plate. A supply passage connects the back pressure chamber to the discharge pressure region and passes through a sliding portion between the movable scroll member and the fixed wall. A clearance at the sliding portion varies in response to a position of the movable scroll member in a direction in which the movable scroll member approaches to or leaves from the fixed wall, whereby cross-sectional area of the clearance where gas passes is varied to adjust pressure in the back pressure chamber.

An electric motor includes a housing and a circular stator. The housing has an inner circumferential surface. The housing also has a first predetermined thermal expansion coefficient. The housing further has an elastic part. The stator core is pressed to an inside of the housing by tight fit. The stator core has an outer circumferential surface. The stator core also has a second predetermined thermal expansion coefficient that is different from the first predetermined thermal expansion coefficient. A void is defined between the inner circumferential surface and the outer circumferential surface so as to prevent the inner and the outer circumferential surfaces from contacting each other in a circular region. When the housing and the stator core expand or shrink so as to tightly fit each other due to a differential between the first and second predetermined thermal expansion coefficients, the elastic part corresponding to the void is elastically deformed.

A scroll compressor includes a housing, a discharge passage, a rotary shaft, a fixed scroll, a movable scroll, an oil separator and an oil reservoir for compressing refrigerant gas containing lubricating oil. The housing has a rear housing which has a partition wall. The discharge passage is formed in the housing. The discharge passage has a discharge chamber, a discharge hole and an accommodation chamber. The discharge chamber and the accommodation chamber are communicated with each other through the discharge hole. The oil separator is provided in the accommodation chamber. The oil separator has a separation member and an oil reserved area. The oil reservoir is defined around an entire circumference of the partition wall which defines the discharge chamber therein. The oil reservoir is formed so as to communicate with the oil reserved area of the oil separator.

A scroll type compressor includes a housing, a fixed scroll member and a movable scroll member. An elastic member is formed in an annular and planar shape and is fixed in the housing on a side of a back surface of the movable base plate so as to slidably contact the back surface of the movable base plate of the movable scroll member at a sliding region of the elastic member. A facing wall is provided on a side opposite to a side of the movable scroll member with respect to the elastic member. A first space is formed between the elastic member and the facing wall for allowing the elastic member to be elastically deformed. The elastic member is elastically deformed toward the facing wall by pressure-contacting the movable scroll member, whereby the movable scroll member is urged toward the fixed scroll member.

When an electric compressor is activated, initial current data is selected by a selector, and a motor is driven with the torque corresponding to the initial current data. When the motor is driven by a &#xbd; turn, the selector selects current difference data. The current difference data corresponds to an instructed speed. After the switch of the selector, the motor is driven to rotate at the instructed speed.
