PRESSURE REGULATOR Russian patent published in 2012 - IPC F02M21/02 G05D16/10 F16K31/122 

FIELD: machine building.

SUBSTANCE: fluid pressure regulator comprises regulating chamber 9 and valve 26. Said regulating chamber 9 accommodated reciprocating piston18. The latter divides chamber 9 into first and second chambers 10, 11, respectively. The latter comprises first and second fluid inlets 12, 13 and outlets 14, 15, respectively. Inlets 12, 13 are communicated with first equipment 2 at first pressure (p_in). Outlets 14, 15 are communicated with second equipment 23 at second pressure (p_out). Piston 18 displaces in response to fluid pressure variation in first chamber 10 to open/close second outlet 15 to adjust second pressure (p_out). Valve 26 serves to open/close first inlet 14 to vary pressure in first chamber 10.

EFFECT: adjustment of regulator outlet pressure.
