摘要:
A compressor having a housing formed by joining a plurality of housing components. A plurality of muffler elements are formed integrally with the housing components along the periphery of the housing. A muffler chamber is defined in the housing by coupling the housing components to one another. A large volume chamber and a small volume chamber are defined in the muffler chamber and connected to each other. An inlet is provided in at least one of the muffler elements for drawing the gas in the discharge chamber into the large volume chamber. An outlet is provided in the muffler elements for discharging the gas in the small volume chamber into the external circuit. The arrangement and construction of the housing is such that the pressure pulses in the discharge gas are reduced, and thus vibration and noise are reduced.

A swash plate type compressor includes an oil separating chamber connected to the discharge chamber for separating lubricant oil from refrigerant gas. A first oil reserve chamber receives the separated oil. A second oil reserve chamber is connected to the first oil reserve chamber. An oil supply port is formed in the valve plate for connecting the second oil reserve chamber to a drive shaft support hole. A restricting member is provided integrally with the discharge valve for regulating the amount of the lubricant oil that passes through the oil supply port.

A compressor includes a housing body and a drive shaft rotatably supported in the housing body. A drive plate is mounted on the drive shaft. Cylinder bores are defined in the housing body. Pistons are operably coupled to the drive plate and are disposed in the cylinder bores. The drive plate converts rotation of the drive shaft to reciprocating movement of the pistons in the cylinder bores. Each piston compresses gas supplied from a suction chamber to the associated cylinder bore and discharges the compressed gas to a discharge chamber. Force to minimize displacement of the drive shaft in the axial direction thereof adjusts in accordance with at least one of pressure in the discharge chamber and a rotation speed of the drive shaft.

A compressor includes a drive shaft rotatably supported on cylinder block. A swash plate rotates in accordance with rotation of the drive shaft. A plurality of pistons reciprocate in the associated bores in the cylinder block in accordance with the rotation of the swash plate. First an second thrust bearings are provided in the cylinder block at both sides of the swash plate, and receive the axial loads applied to the swash plate and drive shaft according to the reciprocation of the pistons. The first thrust bearing has the first seat portion clamped at both sides by the swash plate and cylinder block and the second seat portion located apart from one of the swash plate and cylinder block.
摘要:
A carbon black-graft polymer, produced by causing a polymer possessing within the molecular unit thereof at least one reactive group selected from the class consisting of aziridine group, oxazoline group. N-hydroxyalkylamide group, epoxy group, and thioepoxy group to react with carbon balck. The polymer can be used as a toner for electrostatically charged image, resin composition, coating composition, ink for thermographic transer, coating gent for magnetic recording medium, rubber composition, and carbon black dispersion and the like.
摘要:
A multi-piston swash plate type compressor for an air-conditioning system used in a vehicle such as an automobile, the compressor having combined cylinder blocks closed, at both axial end faces thereof, by front and rear housings each having a radially inner suction chamber and an outer discharge chamber isolated from the suction chamber, valve plates interposed between the axial end faces of the combined cylinder blocks and the front and rear housings, respectively, a plurality of elongated screw bolts axially and hermetically assembling the combined cylinder blocks, the front and rear housings and the valve plates, and an internal sealing and guiding unit arrnaged in the suction chambers of the front and rear housings for rigidly holding the valve plates against a high pressure of a refrigerant after compression, to reinforce the hermetic seal between the axial end faces of the combined cylinder blocks and the valve plates, and for guiding refrigerant flows within the suction chamber to provide a uniform distribution of the refrigerant to cylinder bores formed in the combined cylinder blocks.

A shoe-and-socket joint, which is incorporated into a swash plate type compressor as a drive force transmitting unit arranged between a rotatable swash plate and each of a plurality of reciprocal pistons, has a shoe provided with a spherically formed contact face having a radius R2 and a spherically formed socket recessed in each of the pistons and having a radius R1, the radius R1 being 20 to 150 microns larger than the radius R2, to provide a clearance between the shoe surface and the surface of the socket into which an oil-containing refrigerant can flow to lubricate the shoe surface and the surface of the socket.
摘要:
In the present compressor, a retainer is prevented from being deformed without impairing the sealing performance of a metal gasket provided between a covering member for closing a compression chamber of a cylinder block assembly and a discharge valve forming plate. A discharge valve forming plate is provided between a valve plate having at least one discharge port through which a fluid compressed in a compression chamber of a cylinder block assembly is discharged into a discharge chamber of a housing and the cylinder block assembly. A retainer for restricting the magnitude of opening of a discharge valve is integrally formed in a metal gasket which is provided between the discharge valve forming plate and the housing. The housing is provided with a restricting section at a position corresponding to a proximal portion of a rising portion of the retainer for restricting the proximal portion of the top surface of a rising portion.
