    • A multi-cylinder piston-operated compressor having a cylinder consisting of an axially combined cylinder block closed at both axial ends by front and rear housings having suction and discharge chambers therein, a reciprocative piston mechanism arranged in the cylinder for sucking, compressing, and discharging a refrigerant gas, and a connecting flange from which the refrigerant gas after compression is sent toward an air-conditioning circuit. The cylinder block and the connecting flange define a muffling chamber for deadening pulsation in the pressure of the discharged refrigerant gas. The compressor further has front and rear delivery passageways axially extending from the front and rear discharge chambers and having different axial lengths, to cause a pressure differential between the flow of the discharged refrigerant gas passing through the front delivery passageway and that of the discharged refrigerant gas passing through the rear delivery passageway, thereby producing an agitated flow of the compressed refrigerant gas within the muffling chamber.

    • A swash plate type compressor having a pair of axially combined front and rear cylinder blocks forming therein a plurality of cylinder bores, a swash plate chamber, and an oil chamber in which a lubricating oil is stored to be stirred by a swash plate rotatably received in the swash plate chamber, a drive shaft centrally rotatably mounted in the combined cylinder blocks to cause a rotation of the swash plate, a plurality of reciprocatory double-headed pistons slidably fitted in the cylinder bores and operatively engaged with the swash plate via shoe members to be reciprocated by the rotation of the swash plate, a pair of thrust bearings axially supporting the swash plate, front and rear housings having suction chambers for the refrigerant gas before compression and discharge chambers for the refrigerant gas after compression, the front housing further having a shaft sealing chamber formed therein and separated from the suction chamber thereof to define an intermediate pressure chamber between the high pressure swash plate chamber and the low pressure suction chamber of the front housing, a thin fluid passageway interconnecting the shaft sealing chamber with the suction chamber. The intermediate pressure chamber and the thin fluid passageway prevent evacuation of the lubricating oil from the swash plate chamber to the suction chamber even during the rotation of the compressor at a high speed, to thereby promote a lubrication of the thrust bearings, the shoes, and the swash plate.

    • A piston type compressor having a cylinder block in which a plurality of compression chambers permit a plurality of pistons to be reciprocated so as to compress a refrigerant sucked from a suction chamber formed in an end housing into the compression chambers through suction ports of a valve plate openably closed by a plurality of suction reed valves. The compressor also has a valve stop construction for stopping the movement of the suction reed valves when the valves reach the opening position thereof apart from the valve plate. The valve stop construction includes recessed seats formed in an axial end face of the cylinder block so as to permit a portion of the free end of respective suction reed valves to be first seated on the recessed seats, and to permit the remaining portion of the free end of the suction reed valves to be stably seated on the recessed seats. The gradual stoppage of the suction reed valves suppresses vibration of the valves and prevents noise.
    • 一种具有气缸体的活塞式压缩机,其中多个压缩室允许多个活塞往复运动,以便通过阀板的吸入口将形成在端部壳体中的吸入室吸入的制冷剂压缩到压缩室中 可打开地由多个吸入簧片闭合。 压缩机还具有阀止动结构,用于当阀门到达其与阀板的开启位置时停止吸入簧片阀的运动。 阀门止动结构包括形成在气缸体的轴向端面上的凹座,以便允许相应的吸入簧片阀的自由端的一部分首先坐在凹座上,并允许剩余部分的自由 吸入簧片阀的端部能够稳定地安置在凹座上。 吸入簧片阀的逐渐停止抑制阀的振动并防止噪音。

    • A gasket having a surface thereof coated with an elastic membrane and adapted to be interposed, together with a valve plate and a discharge valve member, between a cylinder block and a housing of a refrigerant compressor under compression. The gasket includes an outer sealing portion for sealing an outer circumference of the compressor against an atmospheric environment therearound, and an inner sealing portion, connected to the outer sealing portion, for sealing between a high pressure region and a low pressure region within the compressor. Each of the outer and inner sealing portions includes in its entirety a deformable ridge which is shaped as a convexly curved projection with an apex line continuously extending along a length of the each outer and inner sealing portion. When the gasket is located in a proper position in the compressor, the apex lines of the ridges of the respective sealing portions are abutted to the front or rear housing of the compressor.
