Claims

[Claim for Utility Model Registration] Inside the cylindrical valve body having a hydraulic inlet and a hydraulic outlet, the hydraulic inlet side is formed as a small-diameter pressure receiving surface, and the hydraulic pressure outlet side is formed as a large-diameter pressure receiving surface, and the valve body is formed in the axial direction. A piston having a fluid passage hole is fitted, and the main piston is biased by a spring toward the large diameter pressure receiving surface side, and the opening of the fluid passage hole of the main piston and a predetermined space are formed on the small diameter pressure receiving surface side of the main piston. In a proportioning valve in which valve bodies are provided facing each other with a gap of A proportioning valve characterized in that a hydraulic pressure application port side fits a differential piston formed on a large-diameter pressure receiving surface, and the working piston and the valve body are connected.
