FIELD: machine building.
SUBSTANCE: invention relates to fluid medium regulators. The fluid medium regulator comprises the regulator housing with an input, connected to a pressurised fluid medium source, first fluid medium valve located inside the regulator housing and connected with an input for regulation of fluid medium, injected towards input, and the second fluid medium valve located inside the regulator housing and connected with an input and through the flow passage - with the first fluid medium valve. The second fluid medium valve is intended for pressure regulation in the flow passage to the value of preset part of upstream fluid medium pressure. The configuration of the second fluid medium valve allows to provide such preselected load ratio, that the fluid medium pressure in the flow passage equals the preset part of upstream fluid medium high pressure.
EFFECT: improvement of reliability and precision of fluid medium regulation.
