Abstract
Abstract A hydraulic propulsion and guidance system for a marine vessel consisting of a fluid pressure generating system and a helm pressure generating unit located within the vessel, a tilting fluid actuator mounted to the transom of the vessel, a lift clevis operatively connected to the shaft of the tilting actuator, a rotary fluid actuator mounted within the lift clevis, a steering clevis operatively connected to the shaft of the rotary fluid actuator, a fluid motor-propeller assembly secured to the steering clevis, an additional fluid pump located within the vessel and fluid conduit operatively connecting same to the tilting actuator such that as the pump is operated the shaft of the tilting actuator rotates the lift clevis in turn tilting the fluid motor-propeller assembly, further fluid conduit operatively connecting the helm pressure generating unit and the rotary actuator such that as the helm pressure generating unit is operated the shaft of the rotary actuator rotates the steering clevis and the fluid motor-propeller assembly, the fluid conduit including single passage oscillating swivels mounted to the transom along a common axis defining the center of rotation of the lift clevis, still further fluid conduit connecting the fluid pressure generating system and the fluid motor including a multiple passage oscillating swivel operatively mounted to the steering clevis and aligned with respect to the axis of rotation of the steering clevis, the aforementioned swivels permitting the use of rigid fluid connections throughout.
