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.
摘要翻译：压缩机具有奇数个对齐的气缸孔对。双头活塞容纳在每对对准的孔中。气体从每个气缸孔排出的时间与所有其它气缸孔的时间不同。压缩机具有一对还原装置，一个减少从前缸孔排出的气体的脉动幅度，另一个减小从后缸孔排出的气体的脉动幅度。减速装置以基本上相等的速率降低前气缸孔和后气缸孔的气体脉动幅度。每个还原装置包括用于接收从相关联的气缸孔排出的气体的排放室和连接到排出室的排放通道。还原装置的放电室具有相等的体积，并且还原装置的排出通道具有相同的长度和相等的横截面面积。该结构改善了压缩机的振动特性，从而降低了噪音。

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 compressor includes a housing body and a drive shaft rotatably supported in the housing body. A swash plate is mounted on the swash shaft. Cylinder bores are defined in the housing body. Pistons are operably coupled to the swash plate and are disposed in the cylinder bores. The swash plate converts a rotation of the swash shaft to a reciprocating movement of the pistons along an inner surface of 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. Deformation of the inner surface of each cylinder bore is reduced by utilizing pressure of the gas compressed in the cylinder bore.

摘要： A swash plate type compressor is provided with a front and rear cylinder blocks having a crank case connected to a suction port. The cylinder blocks include a plurality of cylinders, and are connected to a front and rear housing sections for covering the cylinders. Each housing section contains a discharge chamber. A drive shaft is rotatabley supported by the cylinder blocks. A swash plate is mounted on the drive shaft and is rotatably disposed within the crank case. Two-head pistons move within their respective cylinders in cooperation with the swash plate. The refrigerant is drawn into, and compressed in each cylinder. Thereafter, it is discharged into the external refrigerating circuit through the front and rear discharge chambers, and a final discharge port. A discharge passage includes a hollow primary passage which is provided within the drive shaft. The primary passage communicates with the front and rear discharge chambers. A groove is provided on an inner wall of the primary passage. As the drive shaft rotates, the groove separates the refrigerant from the lubricating oil mixed with the refrigerant. An oil passage is provided between the discharge chamber and the crank case. The separated oil flows from the discharge chamber to the crank case, through the oil passage, and is used again in lubricating the components of the compressor.
