Anti-overrunning device for an internal combustion engine.

摘要

An anti-overrunning device for an internal combustion engine comprising a vibrating pump (41) for generating pneumatic pressure by vibrations of the engine; an actuator (81) for actuating a throttle valve (27) of a carbureter (24) in a direction of closing the valve; and a control valve (61) for controlling a flow of the pneumatic pressure from said vibrating pump (41) to actuator (81) during overrunning of the engine; and said control valve (61) being actuated by virtue of the electromotive force of a generator (13) driven by the engine.
