<P>PROBLEM TO BE SOLVED: To provide an anti-surging device for preventing a surging of a compressor of a supercharger which can avoid the generation of surging even when a point of the generation of surging deviates because of a change in a working environment or secular changes. <P>SOLUTION: The anti-surging device 29 is provided with a means 31 for detecting oscillation, a means 33 for reducing a supercharged pressure and a control means 19. The means for detecting the oscillation detects an oscillation of the compressor 7 at the time of its operation, and the means for reducing the supercharged pressure can reduce the supercharged pressure of the compressor 7. When an oscillation having a short period, which is a sign of the surging of the compressor 7, is detected by the means 31 for detecting an oscillation, the supercharged pressure of the compressor 7 is reduced by the means 33 for reducing the supercharged pressure. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
