Abstract

PURPOSE: To prevent a damage of an engine by warning if melfunction of a relief valve at the exit of a compressor is detected.
CONSTITUTION: A relief valve device 19, whose valve-opening pressure is set slightly higher than the opening pressure of a valve device 18, is provided in a supercharging passage. If the valve device 18 fails to operate due to a seizure of a valve 23, te relief valve device 19 is opened to release excess supercharged air from the line for protecting an engine 2. If there appears an unusual state, a piston 25 of the relief valve device 19 is moved to the right against a spring 26. A window 28 formed in a cylinder 27 is then opened to communicate the supercharging line with the atmosphere, thereby to release supercharged air. Simultaneously, the action of the piston 25 is transmitted to a switching element 20 to actuate a warning device 29 such as a lamp or a buzzer.
