Claims

[Scope of utility model registration request]

(1) A hydraulic valve body having a hydraulic pressure introduction opening, a plunger slidably fitted into the hydraulic valve body and axially moved by hydraulic pressure, and a plurality of valve chambers communicating with each other via valve holes. an air-side valve body having an air-side valve body, a valve flange facing a valve seat formed on an end surface of a peripheral wall of the valve hole, and a valve shaft that is inserted into the valve hole and whose tip abuts the plunger; a valve member that forms a communication path for controlling communication between the valve chambers by its axial movement; a pressing spring that applies repulsive force to the valve member and presses the valve member toward the valve seat; An air control valve comprising a seal ring inserted between a seat and a valve flange and passed through the valve shaft.

(2) The air control valve according to claim 1, wherein the valve member is made of a metal material.

(3) Utility model registration claim 1, characterized in that the communication passage is constituted by a stepped groove whose width narrows in a stepwise manner from the tip of the valve shaft toward the valve flange. Air control valve described in item 1.
