Abstract
A pilot device cooperates with a gas pressure regulator suitable for use in gas distribution systems and consists of: a head with two chambers separated by a first membrane, one chamber at the gas pressure regulator outlet pressure and the other at atmospheric pressure; a body with elastic means and an axial thrust unit acting on the first membrane and cooperating with a regulation unit having at the inlet a supply pressure and at the outlet the motorization gas which is transferred to the motorization chamber of the gas pressure regulator. The pilot device features a tank having a wall with a further membrane provided with the mechanical elastic setting means. Gas is conveyed into the tank with a load pressure to modify the thrust of the elastic setting means. The device has a closed compensation chamber at atmospheric pressure, having the further membrane in common with the tank.
