Patent ID: 8061330

Claim:
A fuel supplying apparatus for a gas engine, comprising: a primary regulator having a pressure-reducing chamber for reducing a pressure of gas fuel to a predetermined pressure, the gas fuel being produced by vaporization of liquefied fuel; and a secondary regulator provided integrally with the primary regulator for reducing the reduced pressure of the gas fuel to a pressure close to atmospheric pressure; wherein the secondary regulator is located below the primary regulator and has a gas inlet communicating with the pressure-reducing chamber of the primary regulator and a gas outlet located below the gas inlet, such that tar separated from the gas fuel flows from the primary regulator to the gas outlet of the secondary regulator, and wherein the secondary regulator has a groove portion extending between the gas inlet and the gas outlet, and a lid covering the groove portion, the lid and the groove portion defining a tunnel-shaped passage for allowing the gas fuel and the tar to flow through the tunnel-shaped passage.
