FIELD: machine building.
SUBSTANCE: gas pressure regulator is fitted with a drive, a control valve and a device of pressure-induced loading. The pressure-induced loading device provides for loading the drive diaphragm surface with pressure which counteracts the output pressure on the opposite diaphragm side with the latter pressure being controlled by the regulator. In case the output pressure is changed the diaphragm moves and shifts the controlling element in order to regulate the output pressure while the pressure-induced loading device keeps up the specified pressure. The pressure regulator can comprise a regulating shutter which compensates the force of input pressure on the controlling element.
EFFECT: increasing efficiency of standard gas pressure regulators.
