摘要： A gas fuel supply apparatus is constructed to be capable of supplying any one of propane gas and butane gas to a gas engine while switching between the propane gas and the butane gas. A check valve is provided in a gas fuel supply passages corresponding to a gas canister containing the gas fuel of a low working pressure (propane gas). The check valve prevents the gas fuel of a higher working pressure (butane gas) from flowing from a downstream side of the check valve to an upstream side of the check valve.

摘要： A fuel supplying apparatus is configured to supply a gas engine with gas fuel in such a manner that tar separated from the gas fuel is guided to the engine. The apparatus includes a primary regulator and a secondary regulator formed integrally with the primary regulator. The primary regulator communicates with the secondary regulator through a gas passage. The secondary regulator is disposed below the primary regulator. The secondary regulator has a gas inlet for taking in the gas fuel and the tar that have passed from the primary regulator through the gas passage. The secondary regulator has an orifice disposed below the gas inlet for discharging the gas fuel and the tar. The tar separated from the gas fuel flows from the primary regulator through the gas passage and the gas inlet into the secondary regulator and discharged out of the orifice into the engine.

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.
