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 compressor has a swash plate supported on a drive shaft for an integral rotation. The swash plate is coupled to a plurality of pistons reciprocally moveable in a cylinder block to compress gas therein. Reaction force of the compressed gas applied to the piston and causing axial load acting on the swash plate and the drive shaft is buffered by buffer structure. The buffer structure comprises a first bearing interposed between a first surface of the swash plate and the cylinder block. The buffer structure has a second bearing interposed between a second surface of the swash plate and the cylinder block. One of the bearings is arranged to be flexibly deformable to absorb the axial load while the other bearing is arranged to be rigid to receive the axial load and transmit the axial load to the cylinder block.

摘要： Disclosed is a compressor designed to facilitate the assembling of the thrust bearing and reduce noise. A swash plate which moves in responsive to the drive shaft is arranged in a crank chamber defined in a pair of cylinder blocks. Ring washers are held between both bosses of the swash plate and seats formed on both cylinder blocks. Wedge-like clearances are formed between the washers and the seats of the cylinder blocks for the effective introduction of the refrigerant gas by the yawing of the swash plate which occurs as the compressor runs. At this time, the washers, together with the lubrication oil mist contained in the refrigerant gas, constitute the dynamic bearing to support the swash plate and permit the relative movement of the swash plate to the cylinder blocks.
