装置。[Claims for Utility Model Registration] (1) In an accelerator control device that controls an accelerator device of an engine that drives a pump in conjunction with an operating section for a directional control valve that controls an actuator that uses the output of the pump, An accelerator control actuator for operating the accelerator device is provided, and a pressure control valve is connected to the actuator, and the pressure control valve adjusts the set pressure by following the operation of the operating section of the directional control valve. An accelerator control device configured to be changed and adjusted. (2) A request for registration of a utility model characterized in that the pressure control valve is integrated into a directional control valve and is configured to change its set control value in accordance with the operation of its operating section. The accelerator control device according to item 1. (3) The pressure control valve has a cam that interlocks with the valve body of the directional control valve, and a cam hollow that is in constant contact with this cam.
The accelerator control device according to claim 2, which is a registered utility model, and further includes a valve spring that changes the biasing force in accordance with the cam hollow.
