Abstract:
This invention relates to certain new and useful improvements in gas-engines; and the improvements have reference to a mixing-valve, whereby the two constituents or ingredients of which the explosive agent is composed can be measured and determined, so as to preserve their predetermined proportions, while the amount of each ingredient is lessened or increased according to the speed at which the engine is traveling and according to the load or amount of labor which it is performing; and the improvements also have reference to the means of actuating the valve-stem and its valves, so that when the engine shall reach the maximum of speed the actuation of the valve shall automatically be discontinued and automatically recommenced upon the lowering of the Speed, for the purposes and in the manner hereinafter more fully pointed out. |
