摘要： In a piston type compressor, a housing includes a cylinder block that forms plural cylinder bores and an accommodating hole at a center thereof. The valve port assembly connected to the cylinder block includes suction and discharge ports, suction and discharge valves made of flapper valves. An end portion of the drive shaft rotatably supported by the housing is slidably accommodated in the accommodating hole. The piston in each cylinder bore and the valve port assembly form a compression chamber. The cylinder block forms therein communication holes that connect each compression chamber to the end portion that forms therein a residual gas bypass passage. The residual gas bypass passage connects one communication hole, which communicates with the high-pressure side compression chamber that has finished discharge process of gas, to another communication hole, which communicates with the compression chamber that is lower in pressure than the high-pressure side compression chamber.

摘要： A piston compressor includes a rotary valve having a suction guide hole. A plurality of introducing passages are formed in a cylinder block to connect compression chambers to the rotary valve. The inner circumferential surface of each cylinder bore has a suction auxiliary recess, which is connected to the outlet of the corresponding introducing passage in the circumferential direction of the cylinder bore at the end of the cylinder bore facing a valve assembly. Therefore, the compressor reduces suction resistance of gas at the beginning of the suction stroke without enlarging introducing passages formed in the cylinder block.
摘要翻译：活塞式压缩机包括具有吸引引导孔的旋转阀。多个引导通道形成在气缸体中，以将压缩室连接到旋转阀。每个气缸孔的内圆周表面具有吸入辅助凹部，该吸入辅助凹部在面对阀组件的气缸孔的端部处在气缸孔的圆周方向上连接到相应的引入通道的出口。因此，压缩机在吸入行程开始时减小了气体的吸入阻力，而不会扩大形成在缸体中的引入通道。

摘要： The object of the present invention is to form a film of a high quality on a constituent part in a compressor. The compressor has a swash plate as a constituent part to be filmed. The swash plate on which the film is to be formed is arranged on a seat of a film forming device. An adhesive layer is formed to the end surfaces of the swash plate in advance. A sheet to form a film is absorbed to a hollow body of a suction device of the film forming device, and press-contacted to the swash plate. The sheet is thus adhered to the end surface of the swash plate.
