Abstract:
A single-side compression type swash-plate compressor wherein, in order to improve the sliding contact performance on the compression side of the iron or aluminum material used therein, at least that plane of a swash plate (14) which is in sliding contact with a shoe (15b) on the compression space side is coated with a sprayed coating layer comprising a copper alloy containing 0.5-50 % of at least one member selected from the group consisting of at most 40 % lead, at most 30 % tin, at most 0.5 % phosphorus, at most 15 % aluminum, at most 10 % silver, at most 5 % silicon, at most 5 % manganese, at most 5 % chromium, at most 20 % nickel and at most 30 % zinc, and the balance consisting substantially by copper and impurities, while at least that plane of the swash plate (14) which is in sliding contact with a shoe (15a) on the side opposite to the compression space is subjected to electrolytic plating, nonelectrolytic plating, lubricant coating, phosphate coating, or hardening.
Abstract:
In order to increase the anti-seizing properties of a swash plate which is a sliding component of a swash plate type compressor, a copper alloy is sprayed onto the swash plate and the following texture/composition controls are performed as required: (a) to produce a mixed texture of a dissolved texture into which atomized bronze powder is dissolved during spraying and an atomized texture into which the same bronze powder is not dissolved, (b) to add no or a small amount of Pb to the dissolved texture, (c) to add Sn, P, Al, Ag, Si, Mn, Cr, Ni, Zn, Pb and/or Bi to copper, (d) to add a hard material to a copper alloy, and (e) to form an intermediate layer comprising an Ni alloy or the like between the sprayed layer and a substrate.
Abstract:
A variable capacity swash plate compressor includes a cylinder block (1) having a central through hole and at least one cylinder bore (6) formed about the central through hole, a drive shaft (5) rotatably arranged in the central through hole, a rotary member (40) rigidly fitted on the drive shaft (5) for rotation in unison therewith, a swash plate (10, 110) slidably and tiltably fitted on the drive shaft (5), the swash plate (10, 110) having a sliding surface (10 a , 10 c ), a linkage (41) connecting the rotary member (40) and the swash plate (10, 110) such that the swash plate (10, 110) rotates in unison with the rotary member (40) as the rotary member (40) rotates, at least one shoe (50, 150) arranged to perform relative rotation on the sliding surface (10 a , 10 c ) of the swash plate (10, 110) with respect thereto, and at least one piston (7, 107) connected to the swash plate (10, 110) via a corresponding one of the at least one shoe (50, 150), the or each piston (7, 107) being reciprocable within a corresponding one of the at least one cylinder bore (6) as the swash plate (10, 110) rotates. The swash plate (10, 110) has a protruding portion (10 e ) formed thereon, which protruding portion (10e) forms a component part of the linkage (41). The swash plate (10, 110) including the protruding portion (10 e ) is subjected to surface treatment by gas sulphonitriding or electroless nickel-phosphorus-boron plating.
Abstract:
A slant plate type compressor (10) with a capacity or displacement adjusting mechanism is disclosed. The compressor (10) includes a housing (20) having a cylinder block (21) provided with a plurality of cylinders and a crank chamber (22). A piston (71) is slidably fitted within each of the cylinders (70) and is reciprocated by a drive mechanism which includes a member having a surface with an adjustable incline angle. The incline angle is controlled by the pressure in the crank chamber (22). The pressure in crank chamber (22) is controlled by control mechanism which comprises a passageway communicating between the crank chamber (22) and a suction chamber (241), a first valve device (19) to control the closing and opening of the passageway and a second valve device (290) to control pressure in an actuating chamber (263). The first valve device includes a bellows valve element (193) and a valve shifting element (195). The valve shifting element (195) of which one end is exposed in the actuating chamber (263) is coupled to the bellows (193) to apply a force to the bellows (193) at another end and thereby shift a control point of the bellows in response changes in the actuating chamber pressure.
