| PROBLEM TO BE SOLVED: To reduce a temperature inside a compressor when an operation is switched to a no-load operation in a low load area and also to reduce a power consumption during the no-load operation. SOLUTION: In the operating range of 35 to 100% in air amount for each specified discharged amount of compressed air 12, based on the detected output of a pressure sensor 82, a speed control is performed by an inverter 88 so that a discharge pressure is maintained at a set pressure P0 while changing the frequency of a motor 48. When the discharged amount of air lowers to 30% or less of the specified discharged amount of air, the motor 48 is operated with a lower limit frequency of f1 and, when the discharge pressure reaches an upper limit pressure P1, an air release solenoid valve 78 is opened to reduce a discharge pressure, and the frequency is lowered to a minimum set speed frequency f0. Namely, a two-step speed reduction control is adopted. COPYRIGHT: (C)2001,JPO | ||||||

| PURPOSE:To prevent abnormal rise of air pressure in an air-water separator device likely to occur as a result of misoperation of a valve, by furnishing a lead rupture plate, for releasing a large amount of air by means of rupture of itself, at an upper part of the air-water separator device. CONSTITUTION:During operation with exhaust valve 5 closed, the air pressure in the piping 4 will rise together with the air pressure in an air-water separator device 23, to cause actuation of a safety valve 21. Because this safety valve 21 has small exhaust gas capacity, the air pressure in the air-water separator device 23 will further rise when a large quantity of suction is to be made through a by-pass valve 9, and attainment of a specific pressure level will actuate rupture of a rupture plate 24, so that damage of the air-water separator device, flow meter 7, etc. can be prevented. | ||||||

| PURPOSE:To prevent intrusion of oil at the bottom of an enclosed container into a suction pipe positively when operation of a compressor is stopped, by keeping the pressure in an enclosed space between a fixed scroll and a revolving scroll higher than the suction pressure by leaking a part of pressure in a discharge chamber into said enclosed space between the fixed scroll and the revolving scroll. CONSTITUTION:When operation of a compressor is stopped and a valve plate 24C of a check valve 24 comes into tight contact with a seat surface 24B, part of high-pressure gas in a discharge chamber 11 is leaked into an enclosed space 4 formed between a fixed scroll 2 and a revolving scroll 3 via a small hole 24E formed in the valve plate 24C and a discharge port 10. Since, with such an arrangement, the gas in the discharge chamber 11 flows back into the enclosed space 4 and pressure in the enclosed space 4 becomes higher than the suction pressure, it is enabled to prevent oil (not shown) at the bottom of an enclosed container from entering into a suction pipe (not shown). | ||||||
