PRESSURE REGULATOR Russian patent published in 2016 - IPC G05D16/10 G01L7/00 F16K17/00 

FIELD: space.

SUBSTANCE: invention relates to pneumatic automatics for space engineering and can be used in various industries for operation with compressed gases at required gas pressure reducing to specified value and automatic maintenance of this pressure in preset limits. Pressure regulator comprises body with inlet and outlet unions and fixed seat with spring-loaded valve, detecting element, loading spring resting on plate and arranged in barrel, adjusting screw, double-arm lever rotation axis of which is fixed in housing, characterised by that large and small arms of bell crank are arranged on one side of axis of rotation, wherein ball is arranged in cylindrical recess of small arm of bell crank, interacts with sensitive element in form of piston moving in sleeve from antifriction material, which is rigidly fixed in housing, and on side surface sensitive element has grooves to accommodate elastic rings with fluoroplastic cuffs, wherein large arm of double-arm lever is pivoted rod interacting with disk, on side surface of which there are grooves to accommodate fluoroplastic rings in contact with annular inserts from antifriction material fixed between body and sleeve.

EFFECT: objective of technical solution is expansion of capabilities of pressure regulator, reduced dimensions, higher efficiency.
