Claim Text:
1. A self-regulated valve assembly, comprising: a valve body having a lower part with an input section for a connection to a tank intended to contain a fluid under pressure and, an upper part with an output for connection to a pipe system; a piston movable in said valve body along a first axis between an open position enabling the fluid to communicate between said input section and said output, and a closed position cutting off the fluid communication, said piston having an upper end section and a lower sealing section; and a spring type module coupled to said piston and to said valve body and biasing said piston to an open position, said spring type module interacting dynamically with said piston at least after an actuation of the valve assembly and during an entire cycle of self-regulation of the valve assembly, imposing a positioning of said piston between the open position and the closed position, allowing fluid communication between said input section and said output under a controlled output pressure, said spring type module positioned between said lower sealing section of said piston and an interior of the tank.
