PURPOSE:To stabilize the feed of fuel gas, by installing such a check valve that transmits no positive pressure of suction pulsation inside a suction pipe in an intake passage at the time of decompressing the liquefied fuel and leading it into a mixer part of the suction pipe. CONSTITUTION:When liquefied fuel of liquefied-petroleum-gas or the like is fed to the mixer part 4 installed in a suction pipe from a vaporizer, there is provided with a check valve 12 in the point midway in the intake passage. With this constitution, pulsation occurs inside the suction pipe whereby gas tries to flow back to the intake passage due to the positive pressure portion but this check valve 12 checks this back-flow. Therefore, the feed of fuel is always stabilizable. |
