摘要： 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.

摘要： A cam plate type compressor includes a cam plate having a boss and the cam plate is located in a crank chamber formed within a pair of casings. The cam plate is rotatable with a drive shaft. The compressor also has two-part bearing structure for supporting the cam plate. The bearing has a buffer structure for absorbing an axial load applied to the cam plate. One of the bearing parts is constituted by a rolling bearing and the other is constituted by a flat sliding bearing.
摘要翻译：凸轮板式压缩机包括具有凸台的凸轮板，并且凸轮板位于形成在一对壳体内的曲柄室中。凸轮板可以用驱动轴旋转。压缩机还具有用于支撑凸轮板的两部分轴承结构。轴承具有用于吸收施加到凸轮板的轴向载荷的缓冲结构。其中一个轴承部件由滚动轴承构成，另一个由平滑滑动轴承构成。
