るエンジン及びポンプの操作装置。 One operating cylinder 6 moves the piston 12 against the spring by supplying hydraulic oil to the head side chamber 6A, and operates the rotation control lever 2 of the engine body 1 to the full speed side A;
The other operation is to operate the discharge control unit 20 in the direction of increasing the discharge amount of the main pumps 3 and 4 by moving the piston against the spring by supplying hydraulic oil to the head side chamber 7A via the head side chamber 6A. The cylinder 7, the operation valve 21 that operates the supply and discharge of hydraulic oil to and from the head side chamber 6A of one of the working cylinders 6, and the head side chamber 6A of one of the working cylinders 6 and the head side chamber 7A of the other working cylinder 7. The head side chamber 6A to the head side chamber 7A is provided in the communicating part.
An operating device for an engine and a pump, characterized in that it is equipped with a check valve 18 which allows hydraulic oil to flow through the cylinder and which opens when the piston 12 of one working cylinder 6 enters the head side chamber 6A.
