20090301443 | FUEL FEEDING DEVICE FOR GAS ENGINE - An engine fuel feeding device that is small-sized and easy to start. A cutoff valve is disposed upstream from a primary regulator provided to a fuel passage from a fuel feeding source to an engine. The cutoff valve is provided integrally with the primary regulator. When the gas engine is stopped, the fuel feeding passage is blocked in front of the primary regulator, gas fuel does not flow in the downstream direction that includes the primary regulator, and the ability of the gas engine to start is enhanced. | 12-10-2009 |
20090308352 | FUEL SUPPLYING APPARATUS FOR GAS ENGINE - 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. | 12-17-2009 |
20100101540 | GAS ENGINE REGULATOR - A gas engine regulator includes a decompression chamber defined internally of the regulator and having a gas inlet through which liquefied gas fuel enters and a gas outlet through which the gas fuel exits. The gas inlet is provided at one end side of the decompression chamber while the gas outlet is provided at an opposite end side laterally spaced via a space from the one end side. The regulator also includes a partitioning wall disposed to surround the gas outlet and having a gas passage communicating with the gas outlet, the gas passage having a passage inlet disposed upwardly of the gas inlet. | 04-29-2010 |
20110088400 | GAS FUEL SUPPLY APPARATUS - 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. | 04-21-2011 |
20110088811 | GAS FUEL SUPPLY APPARATUS - A gas fuel supply apparatus includes: first and second mouthpiece attachment sections capable of detachably attaching thereto mouthpieces of first and second gas containers and provided in communication with each other; and first and second check valves provided in a communication passage, communicating between the mouthpiece attachment sections, in corresponding relation to the first and second gas containers. The first and second check valves prevent a gas fuel, let out from any one of the first and second gas containers, from flowing into the other of the gas containers. | 04-21-2011 |
