02-124515,美國(guó)威格士VICKERS回路變量柱塞泵

這些放大器設(shè)計(jì)用于控制威格士的帶電
氣排量控制的PVH 泵。
放大器的脈寬調(diào)制功率輸出驅(qū)動(dòng)一臺(tái)
單電磁鐵比例滑閥，該滑閥液壓控制泵
的搖架位置。搖架位置和泵輸出的反饋
是來自一臺(tái)旋轉(zhuǎn)反饋傳感器，形成閉環(huán)
控制回路，保證泵的精確輸出流量。
模擬指令輸入信號(hào)可以是同相電流，或

angle of the yoke face creates a reciprocating motion to
each piston within the cylinder block. Inlet and outlet ports
connect to a kidney slotted wafer plate. As the pistons move
out of the cylinder block, a vacuum is created and fluid is
forced into the void by atmospheric pressure. The fluid
moves with the cylinder block past the intake kidney slot.
The motion of the piston reverses and fluid is pushed out of
