  • Oil injection type screw compressor
    Patent number: 5199858
    Abstract: An oil injection type screw compressor which includes an oil tank for separating lubricating oil from gas discharged from a compressor body and collecting the thus separated lubricating oil is constituted such that the oil tank has a substantially L-shaped vertical section composed of a base portion and a column portion provided uprightly on the base portion such that a spacing in the base portion located above an oil storage portion at a lower location in the base portion is formed such that it extends from an upper portion in the base portion to the inside of the column portion, and an oil separating element is provided on the inner side of an exit of gas at an upper portion of the column portion while the compressor body is disposed on the base portion.

  • Oil-cooled compressor
    Patent number: 5176505
    Abstract: To enable the prevention of smearing an equipment and its periphery with lubricating oil, the alleviation of a burden in maintenance of the equipment by reducing a decrement of the lubricating oil, and the lowering of running cost, an oil-cooled compressor has a suction control valve 5 in a suction passage 3 and an air discharge valve 9 in a discharge passage 6 in a compressor body 1. An oil discharge passage 16 is formed for leading outside the lubricating oil supplied to bearing and shaft seal sections of the compressor body 1, an oil return passage 17 communicating with the inlet side of the suction control valve 5, an oil reservoir section 18 located between the oil discharge passage 16 and the oil return passage 17, and an air discharge passage 19 arranged with one end connected to the outlet port of the air discharge valve 9 and its another end reaching the oil reservoir section 18.

  • Oil-cooled compressor and method of operating same
    Patent number: 5171130
    Abstract: An oil cooled compressor includes a compressor body having a low pressure suction passage and a high pressure discharge passage. An oil tank is mounted to the discharge passage such that oil and drain water separated from a compressed gas in the discharge passage collect in the oil tank with water at a lowermost part of the oil tank. A drain water passage separate from a compressed gas discharge passage and an oil discharge passage, connects the lowermost part of the oil tank with a portion of the compressor body which is substantially at the low pressure. Drain water is thereby evaporated from the oil tank and returned to the compressor body.
