METHOD OF CONTROLLING FLOW RATE OF FLUID IN BRANCHED SYSTEMS Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: part of fluid is discharged through one branch and overflow member with fixed pressure drop. Fluid is by-passed also to an actuating mechanism through another branch and valve 2, which is provided with controlled flowing section, and throttle 1. Flowing section of valve 2 is controlled by a pressure drop in its control chambers. Pressure signal is fed from outlet of throttle 1 to one of the chambers and from inlet of valve 2 to another one. EFFECT: simplified method. 2 dwg
