  • Gas engine having roller-shaped rotary slide valve
    Patent number: 6055953
    Abstract: The governor for a gasoline engine is a roller-shaped rotary slide valve (8a, 8b)which permits precise adjustment of the quantity of gas-air mixture supplied to the combustion chamber. The actuation forces for operating the rotary slide valve (8a, 8b) are lower than previously used throttle valves, which permits use of a smaller and less expensive control device for operating the valve.
