FLUID MEDIUM FLOW CONTROL Russian patent published in 2010 - IPC G05D7/01 

FIELD: mechanical engineering.

SUBSTANCE: invention refers to fluid medium flow controls. The flow control of fluid medium consists: of inlet aperture for fluid medium and outlet aperture for fluid medium, and of at least one flow controlling channel with open surface limited with a flat bottom and two side walls communicating with the outlet aperture at the place of connection; cross section of the said channel decreases as distance from the said place of connection increases; also the flow control consists of a resilient diaphragm, and of a support flange whereon the diaphragm is placed. Notably, to control flow of fluid medium, when pressure of fluid medium rises at inlet, the diaphragm closes sections of open surface located further from the said place of connection in the region, wherein cross section decreases with growth of distance from the place of connection.

EFFECT: improved design of device facilitating more efficient control of fluid medium flow.
