Linear thruster

摘要

A linear thruster is disclosed in which a load beam is linearly moved by fluid power relative to a guide beam and a piston. The beams are multisided in cross-section to substantially increase the linear bearing area between the bodies and, thereby, substantially increase the strength of the linear thruster against side forces as well as moments to which the linear thruster might subjected. Internal positioning of the components and energy transmission are maximized and the stroke may be variably adjusted.
