特徴とするポートレスタイプのマスタシリンダ。 A piston that is fluid-tightly and slidably inserted into an inner hole of a cylinder body and forms a pressure chamber in the inner hole of the cylinder body that is constantly in communication with a hydraulic pressure line; a valve rod assembled so as to be slidable in the sliding direction of the piston; the valve rod is provided on the valve rod and comes into contact with a valve seat formed at the bottom of the inner hole of the piston or the cylinder body;
In a portless type master cylinder having a valve body that is separated and controls on/off communication between the pressure chamber and the reservoir tank, and a valve spring that biases the valve body toward the valve seat, the valve body is attached to the master cylinder. A control valve is built into the pipe portion of the reservoir tank, which allows liquid flow from the reservoir tank to the pressure chamber in a free flow, and restricts liquid flow from the pressure chamber to the reservoir tank. Portless type master cylinder.
