Claims

[Claims for Utility Model Registration] (1) A valve body having a valve body housing chamber in which a plurality of valve ports are formed, and a plurality of fluid passages that are substantially perpendicular to each other through the valve ports in the valve body housing chamber; It is housed in the valve body housing chamber of the valve body, and closes each valve port by elastic force until the fluid pressure in the fluid supply side fluid passage exceeds the set pressure, and when the fluid pressure exceeds the set pressure, by contraction. A safety valve comprising an elastic valve body that opens each of the valve ports. (2) A valve body storage chamber in which a plurality of valve ports are formed, a pair of fluid supply passages that extend substantially linearly through the valve holes with the valve body storage chamber in between, and the valve body storage chamber. at least one fluid discharge passage substantially orthogonal to the fluid supply passage through a valve port;
The valve body is housed in a valve body housing chamber of the valve body, and each valve port is closed by elastic force until the fluid pressure in the fluid supply passage exceeds the set pressure, and the fluid pressure is kept at the set pressure. 1. A safety valve characterized by comprising an elastic valve body which opens a valve port of a fluid supplying fluid passage with a high fluid pressure and a valve opening of a fluid discharging fluid passage by contraction when the pressure exceeds the pressure.
