操作OPERATION

該裝置與內燃機驅動的開心式液壓系統一起工作，適用于大多數液壓驅動機械，如空中升降機、起重機和吊桿式裝載機。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.

執行器的工作方式是通過在工作需求循環期間控制發動機油門，使發動機驅動泵達到預定的轉速。當控制閥處于中間位置時，允許發動機返回怠速。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.

節氣門控制裝置能夠感應液壓系統中的四（4）個液位

級別1：發動機怠速且氣門處于中間位置時，油道阻塞導致的背壓。

級別2：在發動機全速運轉且閥門處于中間位置的情況下，由于油道阻塞而產生的背壓。（在運行周期結束時發生）

級別3：系統壓力，閥門處于運行周期，要求的流體壓力小。（如降低支腿）

級別4：在工作循環中需要系統壓力的部分工作時的系統壓力。

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級中的壓力高于3級，則節氣門控制的部分效率可能無法實現。彈簧必須設置為克服2級壓力。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.
