ELECTRONIC PRESSURE REGULATOR

Described herein is a two-stage electronic pressure regulator (). The regulator () comprises an inlet duct (), an intermediate duct (), an outlet duct (), a first, mechanical, valve () arranged between the inlet duct and the intermediate duct, and a second, electronic, valve () arranged between the intermediate duct and the outlet duct. The mechanical valve () comprises a regulation element () rigidly connected to a piston () slidably mounted in a cylinder (), thus defining a first chamber (A) and a second chamber (B) that are fluidically separated by the piston (). The mechanical valve further comprises an elastic element () housed in the first chamber (A) and configured to push the piston () in the direction of opening of the mechanical valve (). The mechanical valve further comprises a fluid duct configured to set in fluid communication the intermediate duct () and the second chamber (B) of the cylinder in such a way that the pressure (P) in the intermediate duct pushes the piston () in the direction of closing of the mechanical valve (). The electronic pressure regulator () comprises a further fluid duct () configured to set in fluid communication the outlet duct () and the first chamber (A) of the cylinder () in such a way that the pressure (P) in the outlet duct () pushes the piston () in the direction of opening of the mechanical valve ().
