Governor device for an engine

Abstract

A governor device for an engine which is simple in construction and easy to adjust, and achieves precise and reliable control of engine speed without contacting the rotating portion of the engine. The governor device consists of a non-magnetic and electrically conductive disk which is rotated in synchronism with the engine; a swing member pivotally mounted for effecting a free-swing action thereof; a magnet mounted on said swing member and providing a magnetic field onto said disk for inducing an electromagnetic force to effect said swing action of the swing member in responsive to the rotation of said disk; a spring member for suppressing said swing action of said swing member in one direction; and a drive mechanism for operating a throttle valve of the engine in opening or closing direction in responsive to the swing action of said swing member.
