FOUR-LINE HYDRAULIC DISTRIBUTOR WITH FLAT ROTARY SLIDE VALVE OF MODULAR DESIGN FOR BUILT-IN MOUNTING Russian patent published in 2003 - IPC

Abstract RU 2219352 C2

FIELD: aircraft industry; hydraulic automatic control systems. SUBSTANCE: invention relates to hydraulic/mechanical drives of aircraft follow-up control systems. Proposed hydraulic distributor contains housing, distributing plate with throttling drain channels, support ring, pressure plate, rotary flat slide valve enclosed by lever secured on control shaft and dividing inner space of hydraulic distributor into two spaces. Housing of hydraulic distributor is made in form of hollow cylinder with two ring sealing elements on outer surface and bottom with neck closed from one end face. End face of open end of cylinder is provided with threaded holes for bolts fixing and rigidly connecting cylinder and distributing plate. Three holes are made on outer side of plate to communicate with control spaces of slave hydraulic motor and pressure space channel. EFFECT: improved reliability of hydraulic distributor, simplified design. 4 dwg
