摘要： A discharge valve for a refrigerant compressor includes a leaf spring 10 for biasing a flexible valve plate 9 which opens and closes a refrigerant discharge port 8. The leaf spring has a centrally deformed portion which engages an intermediate portion of the valve plate. During the initial opening of the discharge port, no spring force is applied to the free end 9a of the valve plate to thereby reduce any opening delay and increase the efficiency of the compressor.

摘要： The lubricating oil pool 11 in the bottom of the shell 1 of a rolling piston refrigerant gas compressor is communicated directly with the space 16 inside the cylindrical piston 4 via a supply passage 10c in a side plate 10. Sufficient clearance is provided between the ends of the piston and the compressor side plates 9, 10 to enable limited communication between the space 16 and the compression and suction chambers 6, 18. The compressor discharge is supplied to the space 7 within the shell, and the resultant differential pressure applied to opposite ends of the supply passage causes a steady flow of oil into the piston interior to properly lubricate the moving parts of the compressor.

摘要： The discharge gas which has been compressed by the compressor main body is cooled by heat dissipation through the heat exchanger, after which it is again returned to the compressor. When the lubricant oil is sucked under pressure of the discharge gas, it is also cooled. Each and every component part of the compressor main body and the electric motor is cooled by causing the cooled discharge gas to pass there through, whereby the temperature rise in the compressor as a whole can be suppressed.

摘要： The vane slot 20 and lubricating oil passageway 21 in the cylinder member 3 of a rotary vane compressor are configured such that the radial length of the slot wall 20a on the low pressure side of the vane 5 is less than that of the opposite wall 20b on the high pressure side. Such a shortened low pressure side slot wall reduces wear by providing improved lubrication at the critical inward edge of the slot (F1), and facilitates the flushing away of abrasive particles formed during the initial seating of the vane. For a horizontal installation the lubricating oil level is maintained below the radially outermost edge of the wall 20a to prevent the oil from being drawn into the low pressure chamber 17 when the compressor is stopped.

摘要： A strainer device for a rotary type compressor includes a rolling piston which rotates with rotation of a rotational shaft, a cylinder plate provided in correspondence to the direction of the outer periphery of the rolling piston, a pair of side plates supporting the rotational shaft, and disposed on both side surfaces of the cylinder plate to define a compression chamber. A suction pipe passes through a shell housing with one end thereof being connected with a suction port formed in one of the side plates to introduce intake gas. A communication path leads the intake gas from the suction port to the compression chamber and a strainer removes foreign substances contained in the intake gas, the strainer being provided in a path formed in the cylinder plate or the side plate, not in the suction pipe, through which the intake gas flows.

摘要： A discharging valve device for a compressor discharges gas compressed in a compression chamber outside said chamber against an urging force of a discharging valve to a valve seat and resistance of breaking a film of a lubricating oil deposited at and near a cacting area formed between the valve seat and the discharging valve. The discharging valve device comprises a discharging port communicated with a compression chamber, a valve seat formed at the peripheral portion of said discharging port and having a curvature in cross section, and a discharging valve which is forcibly in contact with a part of said valve seat so as to open and close said discharging port depending on pressure in said compression chamber, wherein a contacting width of the sealing part formed by the contact through an oil film between said discharging valve and said valve seat is smaller than a contacting width of an oil film formed in case of combination of a flat discharging valve with a valve seat having a uniform curvature in cross section.
