Abstract
PURPOSE: To adequately control the rotary operation of hydraulic motors, by providing selector valves, provided with flow dividing and collecting functions, in a flow branch part from a hydraulic pump to hydraulic circuits for front and rear wheels and in a flow junction part from the both hydraulic circuits to the hydraulic pump.
CONSTITUTION: Supply circuit lines 9, 10, from a hydraulic pump 5 to a hydraulic circuit 7 for driving front wheels 1 and to a hydraulic circuit 8 for driving rear wheels 2, are connected to a supply circuit 11 of a pump block 6. While return circuit lines 12, 13 from the hydraulic circuits 7, 8 are connected to a return circuit 14 of the pump block 6. Then in the flow branch part of the supply circuit 11 and the flow junction part of the return circuit 14, selector valves 15, 16, combining flow dividing and collecting functions, are provided. In this way, only the switching operation of the selector valves 15, 16 can perform the rotary control operation at high and low speed to simplify the operating work.
