PRESSURE REGULATOR Russian patent published in 2016 - IPC G05D16/00 

FIELD: machine building.

SUBSTANCE: group of inventions relates to machine building, particularly to valve construction, particularly to control valves, and can be used in various technological pipelines as controllers of indirect action. Disclosed pressure regulators comprise connected with control medium base with a sensitive element therein (bellows), connected to a housing, having for controlled medium inlet and outlet channels covered by a slide valve, interacting with two opposite sides with coaxial to each other pulsation (oscillation) damper kinematically connected to one side with a sensitive element, and on other - with connected to housing cover controlled by means of a screw spring setting device, characterised by that damper is composed of two interacting inner rods with a slide valve bellows, one of which is installed between slide and sensitive element, second one - between slide and resting on rod of bellows setting spring device, wherein on smaller diameter of support is mounted unit of plate springs enclosed shell in contact with screw, wherein sealing field of slide valve is located above sealing field of housing.

EFFECT: technical result consists in creation of compact small-size pressure regulators with possibility of damping pulsations (oscillations) of controlled and control media.
