Axial gas pressure regulator

An indirectly-acting axial regulator of gas pressure, comprising:

• a first housing connected via a first impulse line to a pre-pilot regulator, the pre-pilot regulator connected to a pilot regulator, the pilot regulator connected by a second impulse line to an upper part of a second housing;
• wherein the second housing houses a membrane;
• wherein the first housing houses an axially positioned balanced nozzle, the nozzle slidingly movably placed in sliding gaskets within the first housing;
• wherein the nozzle is pressed by a spring and an extension;
• wherein the first housing houses a seat with a gasket opposite to the nozzle;
• wherein the seat is squeezed between the first housing and an outlet flange,
• wherein the seat includes openings;
• wherein an upper side of the first housing is coupled to a carrier of the second housing,
• wherein the second housing is composed of a lower part and the upper part,
• wherein the membrane is squeezed between the lower part and the upper part of the second housing;
• wherein a first plate is positioned on an upper side of the membrane and a second plate is positioned on a lower side of the membrane;
• wherein the first and second plates are connected in a central part by a tightener and a support;
• wherein a fixed piston with a performed choking channel is located at a center axis of the tightener and the support;
• wherein a lower end of the piston is slidingly movably located, by, a first guide and, a first set of gaskets, in lower part of the second housing, and an upper end of the piston is slidingly movably located, by a second guide and a second set of gaskets, in an upper part of the second housing, so that a lower portion of the piston contacts a roller;
• wherein the roller is rotatably coupled by a first axle to a first end of a first lever;
• wherein a second end of the first lever opposite to the first end is articulately connected to a support and a middle portion of the first lever is articulately connected to a top end of a second lever;
• wherein a lower end of the second lever opposite to the top end is articulately connected to a third lever;
• wherein the third lever is movably coupled to a lower part of the carrier by a second axle;
• and
• wherein the third lever includes archly bended legs that are movably coupled to the nozzle via plates.
