Summary:The improved servovalve broadly (20) includes: a body (21) having an axis of elongation (y y) a portion of the body defining a cylinder (43) having an axis (x x) substantially perpendicular to the body axis; a valve member (44) movably mounted in the cylinder and adapted to be moved off null in either direction along the cylinder axis to selectively meter the flows of fluid between a plurality of ports defined between the spool and cylinder; a rotor (58) mounted on the body for rotation about the body axis; a motor (69) acting between the body and rotor and selectively operable to cause the rotor to rotate in a desired angular direction relative to the body; and a quill like transfer member (64) acting between the rotor and valve spool.
