<p>PURPOSE: To enable to use easily at least two valve-regulating values, by installing a retaining ring on a regulator part removing upward by sliding with a valve main body, under the pressure applied to a needle-shaped main body through the valve seat. CONSTITUTION: This regulator 12 comprises a valve main body 14 and a weight valve member 16 which is fixed on the valve main body 14 and slides vertically. The weight valve member 16 has a cylindrical, needle-shaped main body 56 equipped with a terminal 58 sealing and co-operating with the seat 32 of the valve main body 14, and has regulator parts 34 and 36 consisting of two parts. The needle-shaped main body 56 is attached slidably in relation to the regulator part 34, a spring 64 is inserted between the needle-shaped main body 56 and the regulator part 36, and the regulator part 36 regulates the force of the needle- shaped main body 56 affected by the spring 64. Furthermore, by the co-operation actions removing upward properly between a shoulder part 44 attached on the outside wall of the valve main body 14 and a deformable elastic ring 42 on the regulator part 34, the regulator 12 is opened, and a part of the pressure inside a pressure cooker is released.</p> |
