摘要： 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

To introduce liquefied gas from a bomb 1 into the primary chamber 3 where the liquefied gas is formed into a low pressure gas. Further, this fuel gas is discharged through an idle fuel passage into an intake-air passage 6 to be fed into an engine. Simultaneously, a secondary valve 31 is opened by a balance spring 26 disposed in an air chamber 22 and under the pressure of fuel gas in the primary chamber 3 to introduce high pressure gas into a secondary chamber 4. Due to the rise of the gas pressure a membrane 21 is displaced toward the air chamber 22 to allow a spring 26 to close the secondary valve 31. Further, upon transition to a low load operation fuel gas is fed from the secondary chamber 4 to a mixer 8 to fed the fuel gas in a area where the venturi vacuum is low.
