ONE-STAGE ELECTROHYDRAULIC POWER AMPLIFIER WITH FLAT SPOOL HYDRAULIC CONTROL VALVE Russian patent published in 2009 - IPC F15B9/03 

Abstract RU 2361120 C2

FIELD: machine building.

SUBSTANCE: proposed power amplifier is designed for aircraft electrohydraulic automatic control systems. The amplifier comprises electro mechanic converter with its output link being articulated, via a lever, with the control member of the flat spool hydraulic control valve. The base of the latter has working openings and working fluid feed and discharge channels. Aforesaid base communicates with electro mechanic converter via the cup. The cylindrical bushing is pressed in the electro mechanic converter lever, along its lengthwise axis. The base of the flat spool hydraulic control valve is linked up with aforesaid converter with the help of a rigid bushing furnished with two face flanges. Radial seal is arranged between the hydraulic control valve base and aforesaid cup.

EFFECT: reduced power of electro mechanic converter, ease of manufacture.
