PURPOSE:To uniformize self-jetting forces by fixing to a valve body a core body, wherein its lower end is closed and a fluid passage open to the hollow region is provided on its side, providing an engaging groove on the peripheries of the upper and lower ends of the core body, covering the core body with a container body having the same size as that of the core body, so that the container body is secured to the core body by caulking the container body against the core body by means of a caulking to secure the former to the latter. CONSTITUTION:A main body comprises a valve body 3, container body 4, pressure auxiliary body 5, etc. The body 3 is made up of a plate gasket 9 with connection hole 8 fitted in a cap 7 with a through hole 6, a valve seat 10 connected integrally with a core body 18, a disk 11 and a spring 12. Engaging grooves 20 are formed on the upper and lower ends of the body 18 and the body 4 is provided around the body 18. The body 4 is made from elastic material which is expanded when it is filled with fluid under pressure and is covered with a protection bag 21. By caulk caulking rings 22 against the peripheries of the upper and lower ends of the body 4, the body 4 is tightly fixed to the elastic body 5 through the bag 21. |
