Abstract
PURPOSE: To permit reliable detection and disposal regarding a failure of operation of an exhaust bypass valve by coupling an intake tube communicating compressor and diesel engine through a pressure switch to an alarm unit.
CONSTITUTION: A pressure switch 14 is provided on an intake tube 5 communicating a compressor 2 and a diesel engine 4, and the tip of a rod 14 of the switch is held in contact with a movable piece of a switch 15 connected to a solenoid controlled valve 22. With this arrangement, when the pressure in the intake tube 5 is extraordinarily increased with a failure of operation of an exhaust bypass valve 8, a diaphragm 18 is leftwardly moved against a compression spring 19 within an atmospheric air chamber to move the rod 20 to the left side so as to bring the movable contact 15 into contact with a fixed contact 15. As a result, the solenoid controlled valve 22 is excited to cause throttling of an oil supply pipe 23, thus reducing the rate of fuel supply from fuel tank 24 to engine 4 and also turning on an alarm lamp 25.
