<p>PURPOSE:To remove trouble on operation due to dust such as carbon in exhaust gas by increasing the working pressure of the bypass valve of the supercharger. CONSTITUTION:Air is pressed by means of the compressor 6 of the supercharger 1. The outlet pressure of the compressor 6 is transmitted to a relay valve 9 as signals by a conduit 9a. The relay valve 9 receiving the signals relays air collecting in an air tank 10 to a conduit 9c from a conduit 9b, flows the air to the pressure chamber 5a of an actuator 5, and increases valve working pressure. When working pressure rises, a diaphragm 8 is deflected against the force of a compression spring 7b, a valve stem 4b is pushed up and a bypass opening 15 is opened, exhaust gas is made escape to a bypass 3, and the revolution of a turbine 2 is not further increased.</p> |
