摘要： 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.

摘要： Disclosed is a compressor designed to facilitate the assembling of the thrust bearing and reduce noise. A swash plate which moves in responsive to the drive shaft is arranged in a crank chamber defined in a pair of cylinder blocks. Ring washers are held between both bosses of the swash plate and seats formed on both cylinder blocks. Wedge-like clearances are formed between the washers and the seats of the cylinder blocks for the effective introduction of the refrigerant gas by the yawing of the swash plate which occurs as the compressor runs. At this time, the washers, together with the lubrication oil mist contained in the refrigerant gas, constitute the dynamic bearing to support the swash plate and permit the relative movement of the swash plate to the cylinder blocks.

摘要： A swash plate type compressor includes an improved thrust bearing for axially supporting the swash plate. The bearing is of a composite type, and includes at least two elastically deformable slide bearing elements. The swash plate and the cylinder block each have seat portions, which are of different diameters. The two bearing elements are compressed between the respective seat portions into an elastically deformed conically-shaped state, with the amount of conical deformation depending upon the amount of axial compression that is applied to the bearing by tightening the assembly bolts of the compressor. In operation, one of the conically shaped slide bearing elements is pressed outwardly against the other by centrifugal force as the compressor shaft rotates. During start up and low speed operation of the compressor, this centrifugal force will have minimal effect, and the bearing elements will rotate with respect to each other, keeping internal frictional resistance low. At higher speeds, however, the centrifugal force will both bind the bearing elements to move together as a unit and will impart additional supportive force to the swash plate that will tend to minimize vibration and noise during operation.

摘要翻译： 斜盘式压缩机包括用于轴向支撑斜板的改进的推力轴承。 轴承是复合型的，并且包括至少两个可弹性变形的滑动轴承元件。 斜盘和气缸体均具有不同直径的座部。 两个轴承元件在相应的座部之间被压缩成弹性变形的锥形状态，其中锥形变形量取决于通过拧紧压缩机的组装螺栓施加到轴承的轴向压缩量。 在操作中，当压缩机轴旋转时，其中一个锥形滑动轴承元件通过离心力向外压靠在另一个上。 在压缩机的启动和低速运转过程中，这种离心力将产生最小的影响，并且轴承元件将相对于彼此旋转，从而保持内摩擦阻力低。 然而，在较高的速度下，离心力将会同时绑定轴承元件作为一个单元一起移动，并且将向旋转斜盘施加额外的支撑力，这将倾向于使操作期间的振动和噪音最小化。

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.
