Abstract

1277419 Fluid-pressure servomotor systems FAIREY HYDRAULICS Ltd 23 July 1969 [1 Aug 1968] 36816/68 Heading G3P Each piston of a tandem actuator for an aircraft control surface is controlled by a respective one of two separate but identical valve assemblies A, B each comprising duplicate spool valves connected to a yoke 23A or 23B pivotally mounted at its mid-point to the end of a T-shaped link 26A or 26B. The heads of these links are connected to radius arms 35 on a shaft 30A or 30B rotatable via radius arms 34 in response to signals from a pilot's control or an autopilot. Spring boxes 30 normally maintain the yokes perpendicular but allow pivotal movement of a yoke about the end of a seized spool to produce twice the normal movement of the free spool. Shafts 30A, 30B are splined to a common shaft (31) located therethrough and supported in bearings 32.
