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.

Articulating nozzle assembly for water jet apparatus

Disclosed herein is an internal combustion engine comprising a cylinder defining a combustion chamber, a primer fuel conduit communicating with the combustion chamber for supplying a primer fuel to the combustion chamber, and a valved supply conduit for introducing an engine maintenance fluid into the primer fuel conduit.
