Abstract
Improvements in the valves of discharge of timed closing, of the type that is mounted directly on a channeling of water under pressure and whose closing and opening are made by means of a piston-obturator that moves in the cylinder of the body of the valve comprising a seat, characterized in that the piston-obturator is constituted by an assembly, without filleting four coaxial parts, two of which rigid, respectively internal and external, form the piston body and are applied one to another elastically enclosing the flexible packing of said piston by the effect of the placement of an O-ring, or actual shutter of the valve that ensures the coaxial locking of said two rigid parts, said O-ring being housed in a groove of the internal part.
