초록 ▼

This invention relates to a marine jet drive having improved operation, especially in regard to having efficient adaptation to propulsion engine and hull design; having a drive shaft with flexible coupling at each end, internal to the jet drive; having through-the-nozzle engine exhaust; having simplified, combined means of steering and reversing; having controllable nozzle aperture and trim control; having combination reverse flow deflector and trim plane; having means to disengage the engine from the jet to obtain true neutral; having protection from and removal of debris in the water intake duct; generally having fewer overhauls, easier serviceability and lighter weight.

대표청구항 ▼

In an improved marine jet drive for propelling a vessel, having a forward end and a rearward end, having a rotatable impeller coupled to a vessel engine, an impeller housing around said impeller, a diffusor housing and nozzle housing attached to and rearward of said impeller housing, an intake duct, disposed forward of said impeller housing, a jet stream emanating rearward from said nozzle housing, the improvement comprising: two deflectors pivotally supported on vertically disposed pivot means, attached to said nozzle housing; at least one baffle rigidly attached to said nozzle housing to prevent escape of said jet stream forward and upward from said at least one baffle; a control mechanism comprising control rods attached to said deflectors, producing the movement of said deflectors to obtain deflection of said jet stream; said mechanism also comprising a bell crank comprising two outer ends, each said outer end pivotally attached to one of said control rods, the actuation of said bell crank about its fulcrum point by a steering means producing movement of said deflectors in unison; and a reversing means, moving said fulcrum point substantially rearward, thereby moving said control rods in unison, closing said deflectors and forward movement of said fulcrum point opening said deflectors.
