Abstract
A water jet propulsion unit having an articulating exit nozzle assembly which serves as both a thrust nozzle and a steering nozzle. The assembly includes a flow-through inner housing or duct having a flanged portion with an inlet and a ball-shaped portion with an outlet, and a convergent nozzle having a spherical socket which fits around the ball-shaped portion of the inner duct. This ball and socket arrangement allows the nozzle to rotate relative to the ball-shaped portion of the inner duct. A limit pin on the duct projects into a slot formed in the nozzle wall to prevent rotation of the nozzle about a centerline of the duct. Abutment of the pin with the ends of the slot limit the trim angle of the nozzle to a predetermined range. A bracket is attached to the nozzle for controlling the angular position of the nozzle relative to the inner duct.
