とする可変気筒制御装置。 A plunger that can slide inside the block and is movable by hydraulic pressure in a direction perpendicular to the sliding direction is installed in the body that is always pressed against the cam, and one end of the valve stem comes into contact with the groove of the plunger during steady operation. When the cam rotates and moves in the same direction as the body slides, the valve at the other end of the valve stem opens and closes, and during cylinder reduction operation, the valve is switched by a signal from a cylinder switching computer. Even if the plunger is pushed by hydraulic pressure and the plunger moves toward the valve via the body due to the rotation of the cam, the valve stem rushes into the escape hole of the plunger and the valve stem does not synchronize with the movement of the plunger. A variable cylinder control device in which a return spring of a body is disposed on the outer periphery of a valve spring that biases the valve in a direction to close the valve in a variable cylinder system that performs cylinder reduction operation as described above.
