LOW POWER CHARGE SYSTEM

LOW POWER CHARGE SYSTEM A low power charge system includes a pilot-operated bypass valve having a unitary spool member movable in response to pressure in a pilot chamber to control fluid communication between a pump and separate low and high pressure circuits. The high pressure circuit includes an a...

Zusammenfassung:	LOW POWER CHARGE SYSTEM A low power charge system includes a pilot-operated bypass valve having a unitary spool member movable in response to pressure in a pilot chamber to control fluid communication between a pump and separate low and high pressure circuits. The high pressure circuit includes an accumulator. A pilot valve includes a unitary shuttle member movable in response to the pressure in the high pressure circuit to control the fluid pressure in the pilot chamber.
