<p>PROBLEM TO BE SOLVED: To provide a hydraulic circuit for the transmission of an industrial vehicle, which can shorten a time lag from the time point of a shift change to the power transmission. SOLUTION: The hydraulic circuit includes a shifting means 66 for a working oil from a pump 15 to change its way to a plurality of clutches 11-14. The pump 15 and the inlet of the shifting means 66 are connected by inlet tubes 27, 62, 63. The outlet of the shifting means 66 and each clutch 11-14 are connected by outlet tubes 34-37. An accumulator 65 for accumulating a working oil from the pump 15 is provided on a branch tube 64 branched from a pipeline 62. In the accumulator the working oil whose volume is enough to fill one of the outlet tubes 34-37 is stored. The accumulated oil in the accumulator 65 is delivered and supplied to either one of the outlet tubes 34-37 through the shifting means 66 when the shifting means 66 is shifted.</p> |
