Claims

[Scope of Claim for Utility Model Registration] (1) A governor throttle valve is provided downstream of the carburetor throttle valve, and a negative pressure piston that drives the governor throttle valve is applied to the negative pressure of the intake passage between both throttle valves. A pneumatic speed governor that responds to the engine speed and controls the rotational speed of the engine, comprising a rod that connects the negative pressure piston and the speed governor throttle valve, and a connecting portion between the rod and the speed governor throttle valve. A pneumatic speed governor for an engine, characterized in that a friction reducing means is provided in the engine. (2) The friction reducing means includes a rod connecting the negative pressure piston and the governor throttle valve, and a rotating part that is rotatable about a shaft fixed to the governor throttle valve and is engaged with the rod. A pneumatic speed governor for an engine according to claim 1, characterized in that it is provided with:
