Description: |
| Abstract:
Gas engines, especially such as are used in oil and gas well operations, are so arranged as to be conveniently subjected to manual control for the drilling operation and for automatic control in the use of the engine in pumping the well, or after the drilling is completed. In the present invention a convenient throttle actuating mechanism and speed sensitive mechanism are combined; It is further desirable in .combination with a gas mixer valve to have a bypass of sufficient capacity to keep the engine operating after the throttle valve is closed and the present invention involves a means by which this may be accomplished. The throttle in a gas engine is rather sensitive for starting and usually starts best with a given throttle. The present invention involves a means for indi eating the throttle opening so that it may be nicely adjusted particularly for the purpose of starting and also for running conditions if desired. The invention also involves iinproveinents in the speed sensitive mechanism particularly adapting it to this type of engine and for use in connection with a throttle.
Claim:
In a gas engine control mechanism, the combination with a valve body; and balanced governor valve mounted in the body; a spring tending to open the valve and balancing the same against fuel pressure to relieve the governor of the gas and spring load; and a speed sensitive device operating to close the valve. |
