Claims

[Scope of utility model registration request]

A valve body is provided with a flow channel extending from an inlet at one end to an injection port at the other end, and has a cylinder hole and a cylinder chamber that communicates with the pressurizing flow channel in communication with each other; A piston portion is formed at the end, and a pressure receiving surface facing into the flow channel is formed on one end surface of the piston portion, and
a piston valve in which the piston portion is slidably fitted in the cylinder hole; a piston forming a pressure receiving surface that receives fluid pressure from the pressurizing flow path and slidably fitted in the cylinder chamber; a spring that is interposed between the piston body and the piston valve and that uses its elastic force to press the piston valve and press the valve body of the valve portion against the seat surface, thereby closing the flow channel; ; and the flow path is opened by pushing up the piston valve against the spring and separating the valve body of the valve portion from the seat surface by the water pressure caused by the pressure water flowing into the flow path. Pressure from jet white
A pressure water injection nozzle valve, characterized in that it is configured to eject force water.
