Abstract

PURPOSE: To easily select desired pilot pressure and improve work efficiency in the above described device used for a snow removing machine or the like, by arranging relief valve, throttle valve and flow regulating valve in parallel connection in the downstream of a pilot pump driven with an engine.
CONSTITUTION: A pilot pump 7 is connected to a power transmission mechanism 2 of an engine 1, and a relief valve 8, throttle valve 9 and flow regulating valve 10 are arranged in parallel connection to a pipe line 11 connecting the pilot pump 7 to a tank 12, then liquid pressure at the upstream side of these valves is guided to an input torque controlling mechanism part 19. In this way, since an increase rate of liquid pressure guided to the input torque controlling mechanism part 19 for speed of the engine is lower in a region of larger work line load while higher in a region of smaller work line load, running line horse power can be fully increased in the region of smaller work line load, permitting the increase of work amount in the work line and the improvement of work efficiency.
