GAS PRESSURE CONTROLLER Russian patent published in 2009 - IPC G05D16/00 

FIELD: physics, control.

SUBSTANCE: invention is related to devices for control of gas pressure and may be used in gas and other industries. Gas pressure controller comprises actuating device with throttle body that contacts with elastic gate, input, output and control chambers, and also pilot with control valve, membrane and adjustment mechanism. Besides input chamber of actuating device is connected via filter and throttle to control chamber and pilot, and pilot is connected to output chamber of actuating device. Besides surface of throttle body that contacts to elastic gate, has convex shape, and contact of elastic gate with convex surface of throttle body is realised with tension, value of which is more than residual deformation of elastic gate.

EFFECT: higher reliability of pressure controller operation and design simplification.
