Abstract

Disclosed is a gas fuel supply system including a main fuel inlet, a pressure regulating valve, a pneumatically controlled shutoff bleeder valve and a main fuel outlet that are connected through pipes. The pneumatically controlled shutoff bleeder valve includes a pneumatic control valve and a shutoff bleeder valve. The shutoff bleeder valve is configured to open or close a gas fuel delivery passage from the main fuel inlet to the main fuel outlet, or configured to discharge the gas fuel in the pipe. The pneumatic control valve is configured to control the shutoff bleeder valve to be in a desired state. The gas fuel supply system does not need connection to an additional gas source, and the gas supply stability is improved.
