GASEOUS FUEL FEEDING DEVICE

PROBLEM TO BE SOLVED: To prohibit the start of a gas engine and immediately stop the rotation of the gas engine in the case of operation when the gas engine is inclined. SOLUTION: A cutoff valve 21 is arranged on a liquefied fuel passage 15 for supplying liquefied fuel to a vaporization chamber 14 from a cylinder 16. The cutoff valve 21 includes a diaphragm 28 on which the pulsating pressure of a crank chamber 4 acts. When negative pressure is applied to the diaphragm 28, the liquefied fuel passage 15 is opened by the cutoff valve 21. A slant cutoff valve 39 is arranged in a pressure passage 34 for transmitting the pulsating pressure to the cutoff valve 21. The slant cutoff valve 39 has a structure of a ball valve so that it responds to the inclination so as to release the pulsating pressure of the crank chamber 4 to the atmosphere. When the pulsating pressure is released to the atmosphere, the liquefied fuel passage 15 is kept in a cutoff state because the diaphragm 28 cannot operate. During operation, the liquefied fuel passage 15 is cut off rapidly corresponding to the inclination. COPYRIGHT: (C)2007,JPO&INPIT
