<p>A pressure regulator for irrigation plants includes a main body with a central conduit having an inlet port and an outlet port for the liquid, a chamber with variable volume fluidly connected to the outlet port for adjusting the pressure variations and having a side wall elastically deformable between a maximum volume configuration and a minimum volume configuration, and a shutter member associated with the elastic wall for sliding in the conduit between a rest position and a work position. The central conduit includes a damping chamber interposed between the outlet port and the regulation chamber to slow the outflow of liquid from the latter towards the former and to avoid the complete emptying of the regulation chamber before the re-opening of the flow through the inlet port upon high water hammering.</p> |
