摘要： A front housing (20) has a shaft hole (210) and an oil path (20a) communicating with a crank chamber (15) and the shaft hole to lubricate a bearing supporting a drive shaft (3) and and a shaft seal contained in the shaft hole. A lubricating oil in the crank chamber (15) is scraped by the rotation of the drive shaft (3). An oil trap (19) is formed at one end of the oil path (20a) to effectively collect the lubricating oil which is supplied through the oil path (20a) to the shaft hole (210). The oil trap (19) is formed by a part of a first thrust race (201b) and an oil receiving groove (20g). The first thrust race (201b) has a plurality of finger portions (201d) bent towards a bottom surface of an annular groove (204) formed in an internal wall surface of the front housing (20). The annular groove (204) has a plurality of fitting holes (20h) for receiving the finger portions (201d) therein in one-to-one correspondence. The finger portions (201d) are fitted into the fitting holes (20h) to thereby inhibit the rotation of the first thrust race (201b).

摘要： This invention discloses a lubricating mechanism of a hermetically sealed scroll type compressor in which an inner chamber of a housing is kept at suction pressure. The compressor includes a drive shaft supported by bearings in inner blocks. The drive shaft is operatively linked to an orbiting scroll which orbits within a stationary scroll. A rotation prevention device prevents rotation of the orbiting scroll. The drive shaft includes an axial bore extending from an open end and terminating adjacent a forward bearing. A pin extends from the end of the drive shaft to the orbital scroll. A passage links the axial bore to an opening at the end of the pin facing the orbital scroll. Radial bores are provided near the terminal end of the axial bore and at the rearward end of the axial bore near a rearward bearing. The radial bores link the axial bore to a suction chamber of the compressor to allow lubricating oil to lubricate the bearings. The narrow passages allows lubrication of the rotation prevention mechanism. In a second embodiment the suction chamber is divided into two sections by a partition wall. An inclined passage links the two sections to allow the lubricating oil to flow.

摘要： A rotation-preventing/thrust-bearing device for use in an orbiting-member fluid displacement apparatus is disclosed. The rotation-preventing/thrust-bearing device includes a discrete fixed portion, a discrete orbital portion and bearing elements. The fixed portion includes a fixed race and ring placed in a groove in an inner surface of the housing. The fixed race and ring are attached to the housing by pins, and the inner peripheral edge of the groove is caulked to the fixed ring. The orbital portion includes an orbital race and ring placed in a groove in an end plate of the orbiting member. The orbital race and ring are attached to the end plate of the orbiting member by pins, and the outer peripheral edge of the groove in the end plate is caulked to the orbital ring. A plurality of pockets are formed axially in the rings toward the respective races. The pockets of the rings face one another in generally aligned pairs. A bearing element is received in each aligned pair of pockets to prevent the rotation of the orbiting member by the bearing elements interacting with the orbital and fixed rings and to carry the axial thrust load from the orbiting member. The rotation of each ring, which is caused by protation-preventing operation, is prevented by both the pins and the caulked connection.

摘要： A wobble plate compressor including a housing having a cylinder block provided with a plurality of cylinders and a crank chamber is disclosed. A plurality of pistons are coupled to a wobble plate and slidably fitted in the cylinders. A drive shaft is rotatably supported in the housing. An inclined plate connected to the wobble plate is rotated by the drive shaft through a rotor. The rotational motion of the inclined plate is converted into nutational motion of the wobble plate. A rotation preventing mechanism in used to prevent rotational motion of the wobble plate. The rotation preventing mechanism has a guide plate extending within the crank chamber, a cylindrical block including a vertical groove formed therein and retaining system for retaining the cylindrical block on the wobble plate such that the vertical groove is slidably fitted on the guide plate. The retaining system includes a female screw formed on one of the periphery of the wobble plate and the upper surface of the cylindrical block and a male screw provided on the other of the periphery of the wobble plate and the upper surface of the cylindrical block. When the male screw is screwed in the female screw, the cylindrical block is securely connected to the wobble plate by the retaining system. The rotation preventing mechanism can thereby be easily assembled and disassembled.

摘要： A slant-plate type compressor including a compressor housing having a cylinder block as disclosed. A plurality of peripherally located cylinders are formed around the cylinder block, and a central bore is formed through the cylinder block. A piston is slidably fitted in each of the cylinders and is reciprocated by a drive mechanism. The drive mechanism includes a drive shaft rotatably supported in the compressor housing, and having one axial end terminating in the central bore. A rearward portion of the central bore is threaded, and an adjusting screw is screwed into the rear portion to adjust the axial position of the drive shaft within the central bore. A spacer is disposed between the inner axial end surface of the drive shaft and the adjusting screw. The spacer includes a plurality of radial projections extending from a peripheral surface, and fitting into corresponding depressions formed in the interior surface of the central bore. The spacer prevents rotational motion of the drive shaft from being transferred to the adjusting screw. Therefore, the position of the adjusting screw and the drive shaft during rotational motion of the drive shaft is constantly maintained.
