Claims

[Scope of utility model registration request]

A suction piston that reciprocates within the case due to venturi negative pressure, a piston rod that is fixed to the suction piston and reciprocates together with the suction piston, a damper chamber defined inside the piston rod and injected with fluid, and the case. A variable bench equipped with a damper body that is fixed and housed in the damper chamber and generates damping force by passage of fluid only when the suction piston moves forward.
In the damper device for the Yuri vaporizer, the damper chamber is filled with air, and a valve means is provided which communicates the damper chamber with a space outside the piston rod through a leak passage and can change the cross-sectional area of the leak passage. A damper device for a variable venturi carburetor, characterized in that the damping force generated by the damping force can be changed.
