操作OPERATION

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.

节气门控制装置能够感应液压系统中的四（4）个液位

级别1：发动机怠速且气门处于中间位置时，油道阻塞导致的背压。

级别2：在发动机全速运转且阀门处于中间位置的情况下，由于油道阻塞而产生的背压。（在运行周期结束时发生）

级别3：系统压力，阀门处于运行周期，要求的流体压力最小。（如降低支腿）

级别4：在工作循环中需要最大系统压力的部分工作时的系统压力。

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.
