Servo valve spool

Abstract

A spool assembly for a second stage of a servo valve comprises a spool having an axis (L) and an opening for a feedback member provided in a central region of the spool extending perpendicular to the axis. An adjustable joint is provided within the spool for securing a feedback member relative to the spool, comprising first and second jaw arms being displaceable relative to each other along the axis of the spool. The jaw arms have opposing clamping surfaces, wherein the clamping surfaces are arranged to be drawn towards each other as the jaw arms are drawn away from each other, such that a feedback member can be clamped between the opposed clamping surfaces of the jaw arms and thereby secured relative to the spool.
