ABSTRACT:
A linear thruster is disclosed in which a load beam is linearly moved relative to a guide beam by fluid power. One or both of the beams are multisided in cross-section to substantially increase the linear bearing area between the beams and substantially increase the strength of the linear thruster against side forces as well as moments while permitting a substantial reduction in the volumetric space consumed by the linear thruster. The fluid power and the energy inputs to the linear thruster may all be positioned at one end of the guide beam.
