Abstract
A rotary/linear actuator of the type having power driven rotary balls adapted to impose a strain wave on a flexible sleeve for purposes of flexing screw threads carried by the sleeve radially into engagement with threads carried by an outer sleeve for purposes of effecting axial displacements of the outer sleeve relative to the flexible sleeve, employs an improved flexible sleeve permitting essentially uniform radial deflection of its screw threads in a direction extending lengthwise thereof. The actuator includes an improved motor mounting arrangement and alternative touch controlled potentiometer constructions. An alternative actuator construction is disclosed, wherein the flexible sleeve is formed as an integral part of an inner sleeve of the actuator.
