Claims (1)
ジン１により可変ポンプ２を駆動するようになし、該可
変ポンプ２より吐出された油圧を操作弁４を介して走行
用モータ５へ供給するようになすと共に、上記可変ポン
プ２の出力セット用レギュレータ１１とモータ用レギュ
レータ７へ供給される油圧を、上記切換えレバ９に連動
する切換え弁１０で断続するようにしてなる油圧駆励車
の油圧回路。A variable pump 2 is driven by an engine 1 whose output can be switched in multiple stages by a switching lever 9, and hydraulic pressure discharged from the variable pump 2 is supplied to a traveling motor 5 via an operating valve 4. At the same time, the hydraulic circuit for a hydraulically driven vehicle is constructed such that the hydraulic pressure supplied to the output setting regulator 11 of the variable pump 2 and the motor regulator 7 is switched on and off by a switching valve 10 interlocked with the switching lever 9.
