キヤブレタ。[Scope of Claim for Utility Model Registration] A suction piston is provided that can freely appear and retract from the bench lily, and as the suction piston moves, the opening area of the main jet is adjusted. - A metering needle that is located in the jet to increase the amount of fuel discharged and is formed with a small diameter part that retreats from the main jet after the engine starts, and a suction chamber that slidably supports the suction piston. , formed in this suction chamber,
A piston breaker hole that is closed by the suction piston that moves due to negative pressure in the manifold after the engine starts; A main air bleed passage that supplies air to the main jet; This main air bleed passage and the above. The piston breaker passage communicates with the piston breaker hole, and when the piston breaker passage is blocked, the main air bleed passage is opened to the atmosphere, and when the piston breaker passage is opened to the atmosphere, the main air bleed passage is opened to the atmosphere. - A variable bench lily characterized by being equipped with a metering rod that restricts the release of the bleed passage to the atmosphere, and a metering rod driving means that moves the metering rod.
carburetor.
