Abstract: 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.

Abstract: A servovalve (15) comprising a motor (16), a motor bias mechanism (20), a first stage valve member (22) adapted to be moved from a first position to a first off-null position, a second stage member (29) adapted to be moved from a first position to a second position with movement of the first valve member (22), a transfer link (34) acting between the first (22) and second (29) valve members, an eccentric drive member (35) acting between the motor (16) and the transfer link (34), the transfer link (34) and drive member (35) configured such that selective movement of the motor (16) causes the transfer link (34) to move the first valve member (22), movement of the first valve member (22) causes the second valve member (29) to move, and movement of the second valve member (29) causes the transfer link (34) to move the first valve member (22) from the first off-null position back to the null position.
