摘要：A control device for an actuator adapted to control a discharge pressure of avariable discharge pump by means of a regulator and capable of ensuring sufficient flowcontrol range of change-over valves with respect to a spool stroke even when the

number of rotations of an engine for driving the variable discharge pump is reduced todecrease a discharge rate of fluid from the variable discharge pump. Elastic force of aspring (38) of a valve (37) constituting the regulator is adjusted by means of a cylinder(41) associated with a throttle lever (42) for controlling the engine. Also, a control valve isarranged so as to be associated with the throttle lever, so that a pressure on adownstream side of the variable discharge pump is increased to change over the valve.
