THROTTLE CONTROL DEVICE FOR ENGINE FOR GENERATOR

摘要

PROBLEM TO BE SOLVED: To increase the opening of a throttle valve when the number of revolutions of an engine is temporarily reduced and to enable maintenance of a waiting operation state even on an operation condition that rotation is easily brought into an unstable state. SOLUTION: A waiting mechanism 29 is provided to oscillate a governor arm 5 such that a throttle valve 2 is closed to a waiting position when a generator is in no load. A first tensile coil spring 28 to energize the governor arm 5 in a direction in which the throttle valve 2 is opened is interposed between the waiting mechanism 29 and the governor arm 5. The waiting mechanism 29 is structured that the governor arm 5 is oscillated such that the throttle valve 2 is opened to a position during generation in a direction in which the rebound of the tensile coil spring 28 is increased. Further, the waiting mechanism 29 is structured that when the generator is in no load, the governor arm 5 is oscillated in a direction reverse to a direction during generation.
