It is sought to provide an oil-free scroll vacuum pump, which can discharge condensed fluid in it to the outside. An oil-free scroll vacuum pump body 1 for withdrawing fluid from a vessel to be evacuated, compressing the fluid and discharging the compressed fluid to the outside, comprises a stationary scroll constituted by a housing half 4 and a lap 7, another stationary scroll constituted by a housing half 5 and a lap 6, and a revolving scroll 3. The housing half 4 has a gas ballast gas inlet duct 10 and an inlet port 4a, and the revolving scroll 3 has a communication hole 3e. Gas is introduced through the inlet port 4e into a sealed space defined by laps of the individual scrolls engaged with one another. The introduced gas is compressed together with compression fluid in the sealed space, and the resultant fluid is discharged through a discharge port 4c to the outside. |

| The invention pertains to a vacuum pump (1) with a closable line (63, 102) through which gas ballast can be fed into the pump chamber (8, 9). To eliminate the danger that a recipient hooked up to the vacuum pump may be charged with air in the event of a pump failure, the invention proposes that the line be equipped with a control valve (59, 60, 61; 98, 99; 109, 110) to regulate the gas ballast feed as a function of operating conditions, such that the line is closed in the event of a pump failure. | ||||||

| PROBLEM TO BE SOLVED: To provide a compact, lightweight and low-cost fluid machine such as a scroll type vacuum pump and an air compressor having reduced noise and vibration and high reliability by using a method of directly injecting cooling gas as a cooling means into a working chamber. SOLUTION: The cooling means for the vacuum pump is constructed in the scroll type vacuum pump 1 by providing a gas introduction hole in a shell plate part of a fixed scroll 10, which is opened at one end in a working chamber of a closed space reduced to 40-60% of Vm and near the minimum clearance between side walls of spiral shape parts near an internal center portion of the working chamber with respect to the maximum volume Vm of a working chamber 15, formed inside with the minimum clearance between side walls of spiral terminal ends, and which is opened at the other end to the atmosphere, and by connecting an injection pipe 6, which makes heat exchange at a cooling part 6c such as a suction pipe having temperature lower than atmospheric temperature, to an atmosphere side outlet of the gas introduction pipe.

| PROBLEM TO BE SOLVED: To fill gas having a sufficient rate into a displacement chamber without narrowing a cross section of a throttle part by arranging a gas filling mechanism for filling as into an intermediate vacuum chamber, and arranging the other gas filling mechanism for filling gas from the intermediate vacuum chamber into the displacement chamber. SOLUTION: A two stage type displacement pump is provided with two pump stages 1, 2, and an intake valve 3 and a discharge valve 4 are mounted on the first pump stage 1 in those pump stages 1, 2. Two pump stages 1, 2 are connected to each other through an intermediate vacuum chamber 5. A first gas filling mechanism 6 is arranged for filling gas into the intermediate vacuum chamber 5, and is provided with a throttle part 9. A second gas filling mechanism 7 is arranged for filling gas from the intermediate vacuum chamber 5 into a displacement chamber 8, and is provided with a throttle part 10. As a gas ballast system can be efficiently formed and a rate for filling gas into the intermediate vacuum chamber 5 can be appropriately set in the throttle part, it is possible to prevent a wrong effect from exerting on a pump characteristic.

| PURPOSE: To resume the leak test effectively by lowering the background level at a mass spectrometric section quickly even when a large quantity of He is mixed into an oil in an oil-sealed rotary vacuum pump due to gross leak. CONSTITUTION: When a measurement at a mass spectrometric section ANAL exceeds a threshold level, a microcomputer unit 4 judges that gross leak has occurred, and controls a solenoid valve GBV fixed to the gas ballast port 21 of an RP2 to open for a predetermined time. Consequently, atmospheric air is introduced through the gas ballast port 21 into the RP2 and He bubbles in the oil are stirred to be discharged quickly through the RP2. Since no He is discharged again from the RP2 at the time of leak test after occurrence of gross leak, the problem of increasing background level at the mass spectrometric section ANAL is solved. | ||||||

| PURPOSE: To provide a two-stage mechanical rotary vacuum pump selectively operable by different characteristics by providing a means capable of selectively injecting oil to a low vacuum stage and a high vacuum stage and a means for supplying ballast gas having the amount in excess of 10% of capabilities of the high vacuum stage capacity (the overall vacuum pump capacity) to the low vacuum stage. CONSTITUTION: A two-stage vacuum pump is provided with a housing 1 and a stator body 2. A high vacuum stage 3, a low vacuum stage and an oil pump 5 are arranged in the stator body 2, and these are rotated by a shaft 7 of a motor 6 through an adapter 8 and provided with rotors having vanes slidably housed in slots. The oil pump 5 feeds oil to an oil box through a pressure relief valve 9 and an oil line 10 and also feeds oil to the low vacuum stage 4 through an oil line 11. A means for supplying ballast gas from a ballast line 14 to the low vacuum stage 4 through a valve 15 is provided on the housing 1. COPYRIGHT: (C)1994,JPO | ||||||
