该装置与内燃机驱动的开心式液压系统一起工作，适用于大多数液压驱动机械，如空中升降机、起重机和吊杆式装载机。This device is designed to work in conjunction with open centered hydraulic systems powered by internal combustion engines and is adaptable to most hydraulically actuated machinery such as aerial lifts, cranes, and boom type loaders.
执行器的工作方式是通过在工作需求循环期间控制发动机油门，使发动机驱动泵达到预定的转速。当控制阀处于中间位置时，允许发动机返回怠速。The actuator operates in such a manner as to bring the engine driven pump up to a predetermined R.P.M. by controlling the engine throttle during work demand cycles. The engine is allowed to return to idle when control valve is in center position.
The throttle control is capable of sensing four (4) levels of fluid pressure as found in hydraulic systems:
Level 1: Back pressure caused by restrictions in the fluid passages with the engine at idle speed and valving in the centered position.
Level 2: Back pressure caused by restrictions in the fluid passages with the engine at full operating speed and valving in the center position. (Occurs at the end of operating cycle)
Level 3: System pressure with the valving in operative cycle requiring the least amount of fluid pressure. (Such as lowering outriggers)
Level 4: System pressure while operating through that part of the work cycle requiring the most in system pressure.
如果2级中的压力高于3级，则节气门控制的部分效率可能无法实现。弹簧必须设置为克服2级压力。If pressures in level 2 are higher than level 3, part of the efficiency of the throttle control may not be realized. The spring must be set to overcome pressure of level 2.
