GAS PRESSURE REGULATOR Russian patent published in 2020 - IPC G05D16/16 

FIELD: gas pressure regulators.

SUBSTANCE: gas pressure regulator comprises gas inlet and outlet channels, housing accommodating control piston and piston displacement control chamber communicating with command pressure system. Gas pressure regulator further comprises a pilot pressure regulator with a reduction chamber interconnected at the inlet to the piston control chamber and the gas inlet channel and to the outlet pipeline at the outlet. Adjusting piston is located coaxially to flow of the reducible medium with possibility of movement at pressure change in the piston control chamber under action of the pilot regulator.

EFFECT: technical result consists in obtaining easy-to-operate and reliable design of gas pressure regulator, providing high accuracy of control in a wide range of pressures.
