摘要： A swash plate type compressor which includes a pair of cylinder blocks. The cylinder blocks contains a crank case and a plurality of cylinders leading to a suction port. A pair of housing sections cover the cylinder blocks, and contain a suction chamber leading to each about the center of the cylinders, and a discharge chamber which is fluidly connected to the cylinders. The cylinder blocks rotatably support a drive shaft. The suction chamber contains a shaft sealing device in order to seal a forward section of the drive shaft. A refrigerant fluid within the crank case is sucked into the cylinders via the suction chamber. A refrigerant passage is provided along the central axis of the drive shaft. A plurality of inlet and outlet ports are connected to the refrigerant passage and to the crank case and suction chamber. The refrigerant passage, the outlet ports and the inlet ports form a refrigerant suction passage. Consequently, the refrigerant concentration in the suction chamber is rendered uniform, and the reliability of the shaft sealing device is improved.

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.

摘要： A compressor has an odd number of aligned pairs of cylinder bores. A double-headed piston is accommodated in each aligned pair of bores. The time at which gas is discharged from each cylinder bore is different from that of all of the other cylinder bores. The compressor has a pair of reducing devices, one reducing the pulsation amplitude of the gas discharged from the front cylinder bores and the other reducing the pulsation amplitude of the gas discharged from the rear cylinder bores. The reducing devices reduce the gas pulsation amplitudes of the front and rear cylinder bores at a substantially equal rate. Each reducing device includes a discharge chamber for receiving the gas discharged from the associated cylinder bores and a discharge passage connected to the discharge chamber. The discharge chambers of the reducing devices have equal volumes, and the discharge passages of the reducing devices have equal lengths and equal cross-sectional areas. This structure improves the vibration characteristics of the compressor and thus reduces noise.

摘要： An improved compressor that is designed to minimize shock and vibration during start-up includes a plurality of pistons, each of which is positioned for movement within a cylinder in order to compress a gas, and conventional motive structure for driving the pistons. Advantageously, the compressor includes a sensor for sensing, from a condition that exists within the compressor, when the compressor is in a start-up phase. The sensor is designed to be operative regardless of the position of the pistons during start-up. Pressure relief structure, responsive to said sensor, is provided for relieving pressure in at least one of the cylinders when the sensor indicates that the compressor is in the start-up phase. This minimizes shock and vibration during the start-up.

摘要： It is an object of the present invention to reduce the abrasion at a pressure receiving portion of the cylinder block, without increasing the manufacturing cost, even when the outer rings of a bearing are jointly rotated and eccentrically fluctuated. The cylinder blocks are made of aluminum alloy comprising, by weight, 1.5 to 3.5% of Cu, 13 to 16% of Si, 0.5% or less of Mg, 1.0% or less of Zn, 1.0% or less of Fe and the remainder of Al. The matrix, except for primary Si crystal, is relatively soft. Primary Si crystals which each independently project from the pressure receiving portions tend to be pushed into the base material by the outer rings of the thrust bearings, so that the levels of primary Si crystals are easily made to be approximately uniform. As a result, the interference and thrust load from the outer rings can be appropriately supported by a large number of primary Si crystals, and a jointly rotating motion and an eccentric fluctuation can be appropriately supported by a large number of primary Si crystals under severe operating conditions.

摘要： A reciprocating piston type compressor for compressing refrigerant gas is provided with a main housing which includes a plurality of parallel cylinder bores arranged around the longitudinal axis of the cylinder block. The main housing has first and second cylinder blocks connected to each other by a plurality of bolts, the cylinder blocks including inner clamping faces and abutting faces. A plurality of pistons are slidably provided within the cylinder bores. An axially extending drive shaft is supported by the main housing for rotation through a pair of bearings. A swash plate is mounted on the drive shaft for rotation with the drive shaft. A pair of thrust bearings are provided between the swash plate and the inner clamping faces of the cylinder blocks to clamp and hold the swash plate therebetween. The clamping force on the thrust bearings from the inner clamping faces is controlled so that the clamping force does not exceed a predetermined allowable upper limit when the compressor is assembled.
