FIELD: engineering industry.
SUBSTANCE: method refers to hydraulic automation and can be realised when manufacturing high-efficiency four-line hydraulic distributors with flat rotary valve, which are widely used in manual or automatic hydraulic drives of aircraft follow-up control systems. Method involves movements (rotations) of flat valve relative to profiled working ports of control channels of distribution plate to both sides from centre (zero) position with the possibility of varying through angle of rotation with rigid fixation through the position from zero to maximum value, for which purpose there used is a plant consisting of a casing with hydraulic distributor block-module under test, with all the parts and control shaft, which are included therein, as well as microcontrol device made in the form of stepless correction and visual inspection mechanism, which is kinematically connected to hydraulic distributor inlet shaft.
EFFECT: improving reliability.
