FIELD: aircraft industry; hydraulic automatic control systems; aircraft follow up control systems. SUBSTANCE: proposed flat slide valve enclosed by control shaft lever is made in form of hollow bushing with centering ring projection on outer cylindrical surface and is installed for simultaneous contact through its end face surface with planes of pressure and distributing plates with overlapping of arc-shaped or rectangular working ports in distributing plate. Size of positive overlapping at pressure cutoff edges formed by contour of central hole of slide valve and drain cutoff edges formed by outer contour of end face surface of slide valve are made with relationship providing leading in opening of pressure cutoff edges of slide valve communicating pressure channel of hydraulic distributor and working throttling ports of distributing plate with slave spaces of power cylinder. EFFECT: improved reliability of hydraulic distributors and enlarged operating capabilities. 5 dwg
