HYDRAULIC VALVE ARRANGEMENT WITH CONTROL/REGULATING FUNCTION
PROBLEM TO BE SOLVED: To provide a hydraulic valve arrangement for controlling/regulating at least one hydraulic consumer of a mobile machine.SOLUTION: The hydraulic valve arrangement comprises a summation interconnection of at least two hydraulic valves, and at least one consumer interconnection of hydraulic valves. Outputs of the summation interconnection are hydraulically connected with inputs of the consumer interconnection. At least one backflow valve R1, R2 is provided in the consumer interconnection. According to the invention, the at least one backflow valve R1, R2 for throttling a consumer return volume flow opens or closes in dependence on a consumer inflow pressure, and comprises at least one main piston 5b arranged in a bushing 6b, and at least two further pistons 9b, 12b arranged in a lid 2b separate from the bushing 6b.
【課題】可動式機械の少なくとも１つの液圧消費部を制御／調節するための液圧バルブ装置を提供する。【解決手段】少なくとも２つの液圧バルブの合流相互接続系と、液圧バルブの少なくとも１つの消費部相互接続系とを備え、上記合流相互接続系の出力部は、上記消費部相互接続系の入力部と液圧的に接続されており、上記消費部相互接続系には、少なくとも１つの逆流バルブＲ１，Ｒ２が設けられている。本発明によれば、消費部戻り体積流を絞るための上記少なくとも１つの逆流バルブＲ１，Ｒ２は、消費部流入圧力に応じて開閉し、かつブッシング６ｂ内に配置された少なくとも１つの主ピストン５ｂと、上記ブッシング６ｂとは別個の蓋２ｂ内に配置された少なくとも２つの別のピストン９ｂ，１２ｂとを備える。【選択図】図５
