An electric compressor includes a compression mechanism that compresses refrigerant, an electric motor that drives the compression mechanism, a drive circuit that drives the electric motor, a housing that forms therein a motor chamber in which the electric motor is accommodated, a cover that is attached to the housing, a rotary shaft, and a relay terminal portion. The cover is configured to cooperate with the housing to form a drive circuit chamber in which the drive circuit is accommodated. Rotation of the electric motor is transmitted to the compression mechanism through the rotary shaft. The relay terminal portion provides electrical connection between a wire of the drive circuit and a wire of the electric motor. The housing includes a partition wall that separates the motor chamber and the drive circuit chamber from each other. The relay terminal portion is disposed between the partition wall and the rotary shaft.

A compressor includes a shell, a compression mechanism and a fitting. The shell includes an opening and defines a chamber. The compression mechanism is disposed within the chamber of the shell. The fitting is attached to the shell at the opening. Working fluid flowing through the fitting flows to the compression mechanism. The opening is partially defined by a first edge and a second edge. The first edge includes a first planar surface and the second edge includes a second planar surface that faces the first planar surface. A first portion of the fitting extends at least partially into the opening and a second portion of the fitting abuts against the first and second edges.

During a pressurization stroke of a high-pressure pump, a cylinder inner wall and a plunger receive a fuel pressure from the pressurization chamber. Meanwhile, an upper housing does not receive the fuel pressure from the pressurization chamber, so that its thickness can be made thin. A cylinder is comprised of a bottom portion, a cylindrical portion and a large-diameter cylindrical portion. When inserting the large-diameter cylindrical portion into a large engaging hole, the bottom portion and the cylindrical portion are not brought into contact with a lower housing. A high liquid-tightness between the bottom portion, the cylindrical portion and a small engaging hole can be ensured.

In a rotary electric machine having an integrated drive control device, a motor housing joined to a mounting housing, which is a cast member, is made of a steel material. Therefore, an outer diameter is reduced and strength for retaining a stator core is satisfactorily ensured even under high-temperature environments.

A variable displacement swash plate type compressor includes a rotary shaft, a swash plate, and an actuator. The actuator includes a partition body, a movable body, and a coupling member located radially outward of the rotary shaft of the swash plate. The movable body has a guide surface for changing the inclination angle of the swash plate and a sliding portion that slides on the rotary shaft or the partition body. When viewed in a direction that is perpendicular to a direction in which the rotational axis of the rotary shaft extends and perpendicular to a first direction, the guide surface has a curved shape that is configured such that a normal of the guide surface and the rotational axis of the rotary shaft intersect in a zone surrounded by the sliding portion in the entire range of change in the inclination angle.

The linear actuator comprises a double-chamber solenoid pump comprising at least one pump coil, a multi-way valve and at least one pump armature that can be moved by energizing the at least one pump coil and is provided with a switching armature by means of which the multi-way valve can be switched and which can be moved by energizing the at least one pump coil. In the method, both the switching armature and the pump armature are moved by energizing the pump coil.

Sealed container (102) houses electric unit (110) equipped with stator (114) and a rotor (116), and compression unit (112) disposed above electric unit (110). Compression unit (112) includes shaft (118) that includes main shaft portion (120) and eccentric shaft portion (122), and cylinder block (124). Compression unit (112) further includes connection portion (136) that connects piston (128) reciprocatively inserted into cylinder (130) and eccentric shaft portion (122), and a thrust bearing that supports a load of shaft (118) in a vertical direction. The thrust bearing includes an upper race in contact with a flange portion of shaft (118), a lower race in contact with a thrust surface of cylinder block (124), and a rolling element. An overall height of sealed container (102) is sized not to exceed a length six times larger than a diameter of piston (128).

In order to improve a refrigerant compressor, including a compressor unit having a compressor housing and at least one compressor element that is arranged in the compressor housing, for compressing refrigerant, and further including a drive unit having a drive housing and an electric motor that is arranged in the drive housing and connector terminals that are arranged on the drive housing, for the electric motor, and further including an electronic functional unit, such that the connection between the refrigerant compressor and the electronic functional unit is achievable as simply as possible, it is proposed that the connector terminals should be provided in a housing that is arranged on the drive housing, and that an electronic functional unit which performs at least one compressor function should be provided in the housing.

The present invention comprises: a blank forming step in which a casing blank (70) is formed by die-casting, the casing blank (70) having a first cylindrical section (41), a second cylindrical section (42), and an annular section (44) which includes a recess (71) recessed toward one side in an axial direction (O) from a first surface (44a) facing the other side in the axial direction (O); and a cutting step in which the inner peripheral surface (42a) of the second cylindrical section (42) and a second surface (44b) of the annular section (44), the second surface (44b) facing the one side in the axial direction (O), are cut to connect the recess (71) to a compression section containing space (42A) within the second cylindrical section (42), thereby forming a flow passage. In the blank forming step, the casing blank (70) is formed such that a part of a side surface (71a) of the recess (71) is disposed radially outside the inner peripheral surface (42a) of the second cylindrical section (42).

A compressor module includes: a driver having an output shaft which is rotationally driven around an axis; a compressor which is disposed side by side in an axial direction in which the axis extends with respect to the driver, and to which rotation of the output shaft is transmitted; a base plate which supports the driver and the compressor from below in a vertical direction; and a storage tank disposed below the base plate and having a tubular shape that extends in a direction including the axial direction, the storage tank being configured to store lubricating oil for the driver and the compressor.
