Abstract
An apparatus for cleaning the interior of a vessel by ejecting a rotating stream of fluid. The apparatus features a gear train driven by the fluid received by an inlet, a stationary housing, a rotatable housing mounted for rotation on the stationary housing about a first axis, and a nozzle for ejecting the fluid, the nozzle being rotatably mounted on the rotatable housing so that the nozzle rotates about a second axis. A gear train is located between the inlet and the nozzle. In addition, a first gear, which, along with the gear train, drives rotation of the rotatable housing about the first axis, and a second gear, which drives the rotation of the nozzle housing about the second axis, are disposed on opposite sides of the second axis. A deflector deflects fluid running along the input drive shaft away from the gear train housing and a passage drains the deflected fluid to the surrounding environment. A swirler swirls the fluid upstream of an impeller, used to drive the input drive shaft, by directing the fluid to flow through a number of inclined passages. A plurality of passages are formed in the stationary housing that place it in flow communication with the nozzle housing. The passages are closely circumferentially spaced around the stationary housing.
