A motor-driven compressor that includes a compression unit adapted to compress refrigerant, an electric motor adapted to drive the compression unit, and a housing that accommodates the compression unit and the electric motor. The housing includes a coupling member. A motor driving circuit is adapted to drive the electric motor. The motor driving circuit includes a circuit board and a capacitor, which is electrically connected to the circuit board. The capacitor includes a side surface and an end surface that faces the coupling member. A resin material is located between the coupling member and the capacitor. The coupling member includes a facing surface that faces the capacitor. The facing surface includes a recess extending away from the capacitor. The recess receives some of the resin material.

Motor-driven compressor

A motor-driven compressor that includes a compression unit adapted to compress refrigerant, an electric motor adapted to drive the compression unit, and a housing that accommodates the compression unit and the electric motor and includes a coupling member. A motor driving circuit drives the electric motor. The motor driving circuit includes a circuit board and a capacitor, which is electrically connected to the circuit board. A capacitor holder holds the capacitor and is coupled to the coupling member. One of the capacitor holder and the coupling member includes a projection, and the other one of the capacitor holder and the coupling member includes an engagement portion that engages with the projection. Engagement between the projection and the engagement portion positions the capacitor holder relative to the coupling member.

Motor driven compressor

A motor-driven compressor includes a metal housing accommodating a compression unit and an electric motor and a resin cover coupled to the housing. The cover and the housing define an accommodation chamber that accommodates a motor driving circuit that drives the electric motor. A metal shield is fixed to the cover and blocks electromagnetic noise. The shield and the cover are stacked together. A sealing member located between the shield and the cover. The sealing member is configured to block entry of foreign matter into the accommodation chamber through a gap between the shield and the cover.

A variable displacement compressor including a drive shaft through which a gas passage extends between front and rear ends of the drive shaft. The gas passage is connected to a suction chamber at the rear end of the drive shaft. The drive shaft includes a first gas inlet passage, which connects the gas passage to a crank chamber through a lip seal, an oil chamber, and a thrust bearing, and a second gas inlet passage, which connects the gas passage to a central portion of the crank chamber. The drive shaft further includes a sleeve movable along the drive shaft as a swash plate inclines to adjust an open amount of the second gas inlet passage in accordance with the inclination angle of the swash plate, that is, the displacement of the compressor.
