摘要： A wobble plate type compressor is disclosed which includes a compressor housing having a plurality of cylinders and a crank chamber adjacent the cylinders therein. A reciprocative piston is slidably fitted within each of the cylinders. A drive mechanism is coupled to the pistons. The drive mechanism includes a drive shaft which is rotatably supported in an opening of a front end plate and extends into the compressor housing. The drive shaft is supported by a radial bearing. The drive shaft is attached on to an end surface of a cam rotor at an inclindation angle .theta..sub.1 and rotates therewith. The angle .theta..sub.1 is determined so that under severe operating conditions the interior surface of the radial bearing and the exterior surface of the drive shaft are uniformly contacted with each other to prevent damages due to partial contact. In alternative embodiments, the radial bearing is formed with a conical inner surface to insure uniform contact between it and the exterior surface of the drive shaft.

摘要： A refrigerant compressor having pistons reciprocated in respective cylinder by a wobble plate driven by an input rotor which is secured on a drive shaft, which compressor has a reduced volume and an improved lubricant system. An end plate of a housing for the compressor supports and bears the drive shaft and is formed with an oil port extending from a shaft seal cavity mounting a shaft seal of the drive shaft to a gap between the end plate and the rotor, with the drive shaft being formed with another oil port extending the shaft seal cavity and a gap between the rotor and the wobble plate whereby the lubricant oil flows through the gap between the rotor and the wobble plate, the oil port in the drive shaft, the shaft seal cavity, the oil port in the end plate, and the gap between the rotor and the end plate in the order. The rotor is formed with an annular recess on a surface thereof facing the end plate and in eccentricity from the rotating axis of the rotor. A valve plate secured between a cylinder block and a cylinder head is formed of a thin ground steel plate or a thin metal plate used for a spring and is formed with discharge and suction openings by punching. The cylinder head is formed with suction and discharge chambers partitioned with a partition wall means which has sharp end projections formed on an end surface thereof to bite into a gasket between the end of the partition wall and the valve plate to firmly secure the gasket. Two service valves are provided on a side surface of the housing which are communicated with the suction and discharge chambers, respectively, of the cylinder head through a hole extending in the cylinder block and the valve plate.

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 piston-type refrigeration compressor having a more secure valve plate seal is disclosed. A cylinder housing is provided with a cylinder block having a plurality of cylinders at one end. The end surface of the cylinder block near the cylinder is coupled to a cylinder head through gaskets and a valve plate. A circular depression is formed on the end surface of the cylinder block to accommodate the gasket substantially within the depression and thereby seal the cylinder block and valve plate. In this way, the outward expansion of the gasket is prevented which prevents the gasket from deteriorating.

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： In a scroll type compressor wherein a fixed scroll (8) has an end plate (8b) and an involute vane (8a) fixed to the end plate and is coupled to a movable scroll (5) so as to define a pair of working spaces therebetween, the end plate of the fixed scroll are formed a pair of cylinders each of which communicates with the working spaces via bypass holes (15a) and (15b) formed in the end plate of the fixed scroll. In each of the cylinders, a cylindrical piston valve member (10) is slidably received for opening and closing the bypass holes. Opening or closing of each bypass hole is determined depending on a position of an axial end of the piston valve member relative to the corresponding bypass hole.

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.
