Abstract

See full text

A marine thruster includes a cylinder with a front opening and a rear opening; radial baffles positioned within an interior of the cylinder to separate the interior into equally divided water chambers; pistons positioned within a corresponding one of the equally divided water chambers; and an inner-ring rotary valve engaged with the cylinder to allow for side intake of water and the separation of each of the equally divided water chambers into a dry section and a wet section by pistons; the pistons engage with a power source, the power source providing axial reciprocating motion; and the pistons push water through the equally divided water chambers.
