。[Claims for Utility Model Registration] An operating piston with the other end of a drive rod connected to the switched device at one end is provided in a cylinder, and the drive shaft is slidable into an insertion hole in a fixed end wall of the cylinder. The working piston part has a spring interposed between the working piston and the fixed end wall part, and has an inlet at one end for introducing hydraulic pressure according to the rotation of the engine, and the other end is connected to the fixed end wall part. A piston-shaped valve body is slidably fitted into a pressure oil introduction cylinder, and a supply port is provided through an end wall of the cylinder and opens into an action chamber between the working piston and the cylinder end wall. and a port provided in the side wall of the pressure oil introduction cylinder are connected via a supply pipe,
A return oil inlet provided on one side of the pressure oil introduction cylinder and a return oil passage opening into the working chamber are connected by a return path, and a return oil outlet is provided on the other side of the pressure oil introduction cylinder, and further It consists of a hydraulic switching piston section with a spring interposed between the piston-shaped valve body and the closed end wall.The piston-shaped valve body is actuated by the balance between the spring and the hydraulic pressure, and the pressure oil introduction cylinder is operated. Open the port and close the return oil inlet and return oil outlet, or close the port and open the return oil inlet and return oil outlet. A hydraulic drive switching device that moves the operating piston and drive rod forward or backward in a manner that allows switching of the device to be switched.
