Claims

[Scope of utility model registration request]

In a mixer that supplies a mixture of fuel gas and air to a gas engine, fuel passages 112, 113, and 114 having openings in the main intake passage 102 of the mixer are blocked while the engine is stopped. Two on-off valves are provided, and when the engine rotates, the intake negative pressure generated in the main intake passage 102 is introduced into the fuel passage 114 from the opening, and the intake negative pressure is reduced. The fuel passages 113, 11 due to the pressure difference between
4; when the engine rotates, the first on-off valve 104 opens at any position in the main intake passage 102 or the intake passage connecting between the main intake passage 102 and the engine cylinder; From a second on-off valve 105 that connects the fuel passages 112, 113 by the difference between the intake negative pressure guided through a negative pressure passage formed separately in addition to the fuel passages 112, 113, 114 and atmospheric pressure. A mixer for a gas engine, wherein the first on-off valve 104 is disposed downstream of the fuel passages 112, 113, and 114 rather than the second on-off valve 105.
