ABSTRACT:
A valve includes a shell defining a space and an aperture through which gas can go into the space. A tube is movable in the space of the shell between a first position for opening the aperture of the shell and a second position for closing the aperture of the shell. The tube includes a tunnel defined therein and an internal annular flange formed on the wall of the tunnel. A seal is located between the tube and the shell. A spring is compressed between the tube and the shell. A core is located in the tube so as to abut the internal annular flange of the tube in the first position of the tube. A rod is formed on a closed end of the space of the shell so as to push the core from the internal annular flange of the tube in the second position of the tube.
