ABSTRACT:
A valve body has three openings: an inlet, an outlet and a flow-back opening, and is provided with an obturator of the flow-back opening and an obturator of the outlet, which outlet obturator is connected by means of a stem with a piston housed in a cylinder communicating with the outlet through a conduit. A recycling conduit places the outlet in communication with a recycling chamber communicating with the flow-back opening through a recycling opening closed by a third obturator, the recycling opening being freed by action of a rod solid to and intervening in conjunction with the second obturator.
