摘要： A fuel supply system for a gas engine is provided that includes a liquefied gas fuel supply source (16), a pressure regulator (10) for regulating the pressure after liquefied fuel fed from the liquefied gas fuel supply source (16) is converted into vaporized fuel, and a mixer for mixing the pressure-regulated vaporized fuel with air and supplying it to a gas engine (E), a shutoff valve (21) being provided in a liquefied fuel passage (15) between the liquefied gas fuel supply source (16) and the pressure regulator (13), wherein the shutoff valve (21) is formed so as to be opened by manual cranking of the gas engine (E). This enables the shutoff valve of the liquefied fuel passage to be opened from when the gas engine is started, even for a gas engine that is not equipped with a battery or even when a battery of a gas engine is not sufficiently charged.

摘要： An engine-start is inhibited when a gas engine is tilted, and the engine is immediately stopped. A shutoff valve (21) is provided on a liquefied fuel passage (15) supplying a liquefied fuel to a vaporizing chamber (14) from a cylinder (16). The shutoff valve (21) is provided with a diaphragm (28) to which a pulsation pressure of a crank chamber (4) is applied, and opens the liquefied fuel passage (15) if a negative pressure is applied to the diaphragm (28). A tilting shutoff valve (39) is provided in a pressure passage (34) transmitting the pulsation pressure to the shutoff valve (21). The tilting shutoff valve (39) which has a ball valve releases the pulsation pressure of the crank chamber (4) to an atmospheric air. If the pulsation pressure is open to the atmospheric air, the diaphragm (28) can not operate. Accordingly, the liquefied fuel passage 15 is kept being shut off, and is rapidly shut off in response to the tilt during the operation.
