Abstract

The invention regards a valve (10) comprising a first body (100) and a second body (200). Each body houses a piston (102, 202) slidable between a rest position and a work position. Each body moreover comprises a work chamber (108, 208) adapted to receive a fluid under pressure. Each piston comprises a surface (104, 204) which faces on the work chamber. Each body moreover comprises an opening (110, 210) opened and closed by the piston in its movement between the rest position and the work position and vice versa. The second body (200) moreover comprises a reducer (212) adapted to cover part of the second surface (204) and to expose only a portion (204') to the action of the fluid under pressure. The first opening (110) places the first work chamber (108) in communication with the second work chamber (208). The first surface (104) is smaller than the second surface (204); the portion (204') of the second surface (204) is smaller than the first surface (104).
