FIELD: transport.
SUBSTANCE: invention relates to rocketry and can be used for maintenance of preset consumption of fuel components at engine inlet pressure variation. This device has regulator with appropriate orifices, case with inlet and outlet chambers with bellows-like sensitive element with fixed flange secured at device case outlet and moving flange arranged at device inlet. In compliance with this invention, said bellows is spring loaded by compression spring while said orifice is made in bellows moving flange to interact with fixed shaped regulator. Additionally, one or several orifices can be made in fixed flange to communicate inlet and outlet chambers.
EFFECT: higher precision of control over working body consumption.
