Improved decompressor piston, characterized by being formed by a piston whose head is equipped at one end with a collar of elastic material which is made axial contact with a thin ring whose outer diameter is perfectly adjusted to the inside diameter of the cylindrical container housing of the whole assembly, this thin ring being axially supported on a movable arc which is anchored to the piston by a difference in diameters in such a way as to allow a relative axial movement of the ring collar and movable ring assembly.

Spinning axis self-locked in its angular movement in an end, and in its axial displacement of the two. (Machine-translation by Google Translate, not legally binding)
