摘要： A spool assembly (100) for a second stage of a servo valve comprises a spool (110) having an axis (L) and an opening (112) for a feedback member (200) provided in a central region (114) of the spool extending perpendicular to the axis. An adjustable joint (120) is provided within the spool for securing a feedback member relative to the spool, comprising first and second jaw arms (122, 123) 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. The first jaw arm may extend from a first spool end (116) to the central region and the second jaw arm may extend from a second spool end (118) to the central region, each jaw arm providing a tensioning portion (124, 125) in the spool end and a head portion (126, 127; 401, 402) in the central region. The head portions of the first and second jaw arms may each provide a head (126a, 127a; 401 a, 402a); the head of one jaw arm may be positioned beyond the head of the other jaw arm in a direction along the axis of the spool, the head having the clamping surface. The heads may be arranged to be drawn towards each other when under tension from the tensioning portion.
