FLOW CONTROL DEVICE WITH INTEGRATED PRESSURE DETECTOR

摘要

Fuel from a centrifugal pump enters the regulator at an inlet and leaves via an outlet. A proportioning piston slides in a hollow cylinder whose upstream chamber is filled at a first pressure. The fuel passes through a proportioning oriface between a shoulder of the cylinder and a tapered part of the piston, filling the downstream chamber at a second pressure. The pressure drop is maintained constant by a detector and regulating valve placed end-to-end inside the hollow piston. The upstream pressure is communicated via an external link to a bellows operating a slider (24) which corrects the pressure difference.
