摘要:
A swash plate (3) incorporated in a swash plate type compressor and comprising a boss (10) typically formed of aluminum material, which is fixedly secured on a drive shaft (2), and a swash plate assembly (11) extending obliquely from the boss (10), which assembly comprises a pair of front and rear contact plates (12) made of iron and brought into contact with a pair of shoes (6) which are accommodated in recesses (15a) of a piston (5), a connecting member (13) made of iron rigidly connecting the pair of contact plates (12), and a filler (14) made of aluminum material which completely fills the internal spaced formed between the contact plates (12). According to this structure, the change of the distance between recesses (15a) for accommodating the shoes (6) due to the expansion or shrinkage of the piston (5) is compensated by the change of the thickness of the plate assembly (11), whereby the shoe clearance is always kept constant even during a high speed operation of the compressor or in an operation in a low temperature atmosphere, while the slidability of the shoe (6) against the contact plate (12) is maintained at the same level.

A swash plate (3, 18) included in a swash plate type compressor for compressing a refrigerant is made of an aluminum alloy as a base material. Sliding contact surfaces (3a, 18a) of the swash plate (3, 18) in sliding contact with shoes (7, 19) linking the swash plate (3, 18) to pistons (6, 17) are coated with a film of a solid lubricant containing at least one lubricating material selected from molybdenum disulfide, tungsten disulfide and graphite by a transfer method. Therefore, the performance of the film and the productivity thereof are improved.

A carbon black graft polymer which excels in stability of dispersion in various media, coloring property, and imperviousness to light is obtained by mixing under heating a block- or graft-copolymer having a segment (A) containing a reactive group capable of reacting with a functional group on the surface of carbon black and a segment (B) different in skeletal structure from the segment (A) with carbon black. The carbon black graft polymer, by causing the graft chain thereof to incorporate therein an ethylenically unsaturated double bond and/or a carboxyl group, is enabled to manifest photosensitivity, developability with an alkali, and insulating property and acquire usefulness for a black photocurable resin composition such as, for example, the material for the formation of a black matrix particularly in a color filter.

An improvement of a piston type compressor is disclosed. The compressor has a cylinder block that includes a plurality of cylinder bores and a plurality of suction passages. Each of the suction passages extends through the cylinder block to connect a crank chamber with a suction chamber. The suction chamber is connected with the cylinder bores via a plurality of suction ports located in association with the cylinder bores. Each cylinder bore accommodating a piston that moves therein to circulate gas between the compressor and an external gas circuit. The gas introduced into the crank chamber from the external gas circuit is supplied to the suction chamber through each suction passage and is supplied from the suction chamber to each cylinder bore through an associated suction port. The suction passages are smaller in number than the cylinder bores. The suction ports are disposed in the vicinity of an opening of the suction passages.
摘要:
A piston for a compressor. The piston has a lubricating coating that slidably contacts with an inner surface of the cylinder bore. The layer is formed on the surface of the piston. The layer is formed by transferring a liquid material to the surface of the piston using printing techniques such as screen printing and roller coating.

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.
