INLINE BACK PRESSURE REGULATING VALVE Russian patent published in 2016 - IPC G05D16/10 

FIELD: machine building.

SUBSTANCE: present invention in general relates to fluid medium regulators and, in particular, to inline back pressure regulating valves. Back pressure regulating valve comprises case forming a measuring chamber and outlet of the fluid path in the fluid medium. Note that outlet opening communicates with the measuring chamber by fluid medium through the first flow channel in the housing of the regulating valve. Regulating valve also includes cover connected to the housing and forming an inlet opening of the fluid path and load chamber placed between the measuring chamber and inlet opening. Note here that load chamber is essentially sealed relative to the path of the fluid medium in regulating valve. Besides, flow control includes a pressure sensor, placed between the inlet opening and the measuring chamber to make the second flow channel for connection of inlet opening and the measuring chamber by fluid. Pressure sensor is configured to move relative to the valve seat, arranged in the first channel for fluid flow to adjust fluid flow between the measuring chamber and outlet.

EFFECT: technical result is enabling reduction of dimensions or footprint in comparison to common back pressure regulating valves, as well as possibility of load chamber isolation from the environment and/or the fluid path in the fluid medium so that pressure fluctuations in the environment not exposed to required preset load of back pressure regulating valve.
