摘要： A compressor includes front and rear cylinder blocks, a drive shaft rotatably supported by the cylinder blocks, a swash plate mounted on the drive shaft, a plurality of cylinder bores defined in the cylinder blocks and located around the drive shaft, and a plurality of pistons respectively disposed in the cylinder bores. The pistons reciprocate by converting rotation of the drive shaft with the swash plate. A plurality of compression chambers are defined in the cylinder bores for compressing the gas supplied to the cylinder bores in accordance with the reciprocating movement of the pistons. Each compression chamber has dead volume defined by a space having a predetermined volume when the associated piston is at top dead center in each cylinder bore. A reference capacity is defined by the capacity when the piston is at a bottom dead center of the cylinder bore that has the smallest dead volume. The largest dead volume is greater than the minimum dead volume by approximately four percent of the reference capacity.

摘要： A swash plate type compressor incorporating therein a swash plate having an annular rail raised from each flat face thereof for providing a sliding-contact surface being in contact with sliding-contact surface portions of respective shoes which constitute a rotation-to-reciprocation conversion unit arranged between the swash plate and double-headed pistons reciprocating axial cylinder bores of the compressor. The sliding-contact surfaces of respective shoes bulge outward and have a radius of curvature "R" in the range of 800 through 1600 millimeters which is smaller than that of the conventional shoes of a swash plate type compressor, so that relatively large wedge shaped gaps are formed between the respective shoes and the swash plate to thereby stably and constantly hold lubricating oil.

摘要： A refrigerant compressor of the type in which a cylinder block and front and rear housings made of an aluminum alloy are fastened together by means of a plurality of bolts made of a ferrous metal and extending through part of the refrigerant gas passage in the compressor and respective bores formed in the front housing, is disclosed. Each of the bolts has a head supported on a bearing surface formed on said housing means, the bearing surface being formed by an annular projection concentric with the bore in the housing. The annular projection is plastically deformed by the bolt when the compressor is assembled, and the bolt head is carried by such deformed annular projection so that an increase in the tightening force is taken up by the elasticity of the projection.

摘要： A swash plate compressor in which a drive shaft is rotatably supported in a cylinder block having a crank chamber. The swash plate is rotatably disposed on the drive shaft. Thrust bearings are individually fitted between the movable thrust receiving faces of the swash plate and the stationary thrust receiving faces of the cylinder block. As the drive shaft rotates, the swash plate likewise rotates and reciprocates a piston to compress a refrigerant gas. Annular movable ridges are formed on the front and rear side faces of the swash plate concentric around the drive shaft. Stationary ridges are formed concentrically with the movable ridges on the cylinder blocks to face the individually movable ridges. The stationary ridge has a smaller radius than that of the movable ridge. At the front and rear sides of the swash plate, the facing circumferential portions of the movable ridges and the stationary ridges are individually formed with movable and stationary thrust receiving faces for supporting the elastically deformable thrust bearings. At least one of the movable and stationary ridges are formed with escape faces so as to merge into the movable and stationary thrust receiving faces, for establishing escape faces normally between the corresponding thrust bearings. These escape faces expand and reduce the gaps when the thrust bearings are elastically deformed by the action of the swash plate due to the compression reaction forces caused by the reciprocation of the piston.

摘要： A swash plate type compressor comprising a swash plate accommodated in a swash plate chamber. Front and rear housings are attached to the cylinder block to form suction chambers and discharge chambers, respectively. A refrigerating medium is introduced from a suction inlet to the suction chambers via the swash plate chamber and discharged from the discharge chambers. A drive shaft is fixed to the swash plate for reciprocally moving pistons. The drive shaft has a discharge passage in the form of an axial bore formed in the drive shaft for connecting the front discharge chamber to the rear discharge chamber. The discharge passage is thus isolated from the suction system.
