摘要： A compressor includes a rotary shaft, a cam, a cylinder block, pistons, a thrust bearing, a rotary valve, and an oil passage. The rotary shaft has an in-shaft passage formed therein. The cam rotates integrally with the rotary shaft. The pistons are coupled to the rotary shaft through the cam. The thrust bearing is provided between the cam and the cylinder block. The thrust bearing includes a first race in contact with the cam, a second race in contact with the cylinder block, and rolling elements retained between the first and second races to form a gap therebetween. The oil passage extends from the gap to the in-shaft passage and includes an oil retaining space formed in at least one of the cam and the cylinder block.

摘要： A motor-driven compressor includes a compression unit, an electric motor, a drive circuit, a first housing, a second housing, and a soundproofing material. The second housing covers at least part of an outer surface of the first housing. The soundproofing material is arranged between the outer surface of the first housing and an area that includes an inner surface and a wall surface of the second housing. The soundproofing material has sound insulating properties. The soundproofing material includes a sound absorbing layer and a sound insulating layer. A first region and a second region are formed between the outer surface of the first housing and the area that includes the inner surface and the wall surface of the second housing. An air layer is formed in the second region.

摘要： An electric compressor includes a compression portion, an electric motor, an inverter, a housing, a support bracket, a vibration insulator, and a soundproofing cover. The compression portion is configured to compress a fluid. The electric motor is configured to drive the compression portion. The inverter is configured to drive the electric motor. The housing includes an outer peripheral surface that has a cylindrical shape and accommodates the compression portion, the electric motor, and the inverter. The support bracket is fastened to the housing and supports the housing to an object to which the electric compressor is mounted. The vibration insulator is interposed between the support bracket and the object. The soundproofing cover is made of an elastically deformable sound absorbing material and covers the housing and the support bracket.
