ABSTRACT:
The throttle of an engine is controlled to maintain its speed substantially constant in spite of variations of load upon it. The illustrated load comprises hydraulically operated equipment in a hydraulic system powered by a pump driven by the engine. Throttle control mechanism comprises a pair of cylinders supplied from fluid pressure in the hydraulic system. Pistons in the respective cylinders are connected by pivots with a control arm linked to the throttle control. When equipment is hydraulically operated from the hydraulic system, the fluid back pressure against the pump increases, this back pressure being greater the greater the hydraulic load. The increased load on the engine from the pump would slow the engine down if its throttle opening were to remain at its original setting. The function of the throttle control mechanism operated from the hydraulic pressure from the pump, is to move the control arm by a proper amount to open the throttle a sufficient amount to keep the engine speed up to its normal value regardless of changes of load. Compression springs adjustable from adjustable bushings at the cylinders provide a counter-pressure opposing the pressure from the fluid in the cylinders and by suitable adjustment of these bushings the throttle can be made to open or close further in accordance with changes of load to maintain substantially constant engine speed which will maintain uniform flow of fluid through the hydraulic system regardless of load thereon.
