PRESSURE REGULATOR FOR IRRIGATION PLANT AND IRRIGATION PLANT COMPRISING THE REGULATOR
First Claim
1. A pressure regulator for irrigation plant, comprising:
- a main body comprising a primary circuit for the passage of an irrigation liquid having an inlet port connectable to a feeding line for said liquid and an outlet port for supplying said liquid;
a shuttering element operatively associated to said primary circuit and designed for moving between a first and a second working end conditions corresponding, respectively, to the minimum and maximum values of the flow rate from said outlet port;
regulation means associated to said shuttering element to bring it in any regulation working condition between and/or corresponding to said first and second end conditions;
wherein said regulation means comprise a secondary circuit fluidically insulated with respect of said primary circuit and designed for containing a working fluid adapted to apply a pressure on said shuttering element and adjusting its regulation condition.

Abstract
A pressure regulator for irrigation plants comprises a main body (2) with a primary circuit (3) for the flow of an irrigation liquid, a shut-off element (6) operatively associated with the primary circuit (3) and designed to move between a first and a second working end conditions corresponding, respectively, to the minimum and maximum values of the flow rate from the primary circuit (3), regulation means (10) associated with said shut-off element (6) to move it in any regulation working condition between and/or corresponding to said first and second end conditions. The regulation means (10) comprise a secondary circuit (11) fluidically insulated with respect of said primary circuit (3) and designed to contain a working fluid adapted to apply pressure on said shut-off element (6) and adjusting its regulation condition.
