    摘要: A speed control apparatus for an internal combustion engine including a poppet valve seat and a poppet valve pintle assembly disposed coaxially for variably regulating the flow of air into the engine across the valve seat. The pintle is axially positioned by a stepper motor actuator responsive to an engine speed sensor and electronic controller. The controller varies the axial position of the pintle in accordance with a programmed algorithm to provide any desired engine speed, and especially a fixed engine speed, under a range of engine loads. The invention eliminates the need for a governor, rotary mechanical throttle, and cable or mechanical linkages, and is especially useful for small engine applications such as in powering a portable electric generator, yard equipment, or outboard motor.

    摘要: A rotational speed damper operable to dampen the speed of a gear by gradually decreasing the rotational velocity and angular acceleration of the gear over a time period beginning at the time the damper contacts the gear stop and ending at the time the gear reaches its first stopping point.
