Claims

[Claims for Utility Model Registration] A control valve for a brake on a railway vehicle, characterized by comprising a control valve body 1, a first solenoid valve 2, and a second solenoid valve 3 as described below. (1) It has a cylindrical container-like external shape, and is divided into first, second, and third (hereinafter referred to as upper, middle, and lower) chambers in order by partition walls perpendicular to the axis, and The room consists of a large diaphragm placed parallel to the bulkhead,
It has a connection port at the top and a connection port at the bottom, and the second chamber passes through the supply diaphragm and the partition wall with a clearance and is connected between these diaphragms, which are arranged in parallel with the diaphragm of the same size. It has a presser foot, a supply valve seat facing the supply diaphragm and communicating with the chamber below, and a connection port at the bottom, and the third chamber has an exhaust diaphragm disposed parallel to the partition wall, one end of which is connected to the third chamber. The control valve body has an exhaust valve seat which faces the same exhaust diaphragm and whose other end serves as one connection port at the top, another connection port at the top, and a connection port at the bottom. (2) A first solenoid valve of three-port switching type, in which a common port is connected to the connection port at the top of the chamber above the control valve body, and one of the switching ports (on port) is open. (3) At the other switching port of the first solenoid valve (on),
One of the switching ports (off port) is connected and connected to a pipe connected to a connection port of a chamber in the control valve main body, and the other switching port is an opening,
a 3-port switching type second solenoid valve whose common port is connected to a connection port at the bottom of the chamber below the control valve body;
