Abstract:
1. A method for cleaning surface defining a cavity, the method comprising the steps of: providing a manifold body having a first axis therein and first and second outer conical fluid diversion surfaces; providing a ring disposed about the manifold having at least one inner surface, at least one outer surface, first and second inner conical fluid diversion surfaces facing the first and second outer conical fluid diversion surfaces, respectively, and adjacent both the inner surface and outer surface and a central axis aligned to the first axis of the manifold body, secured to the manifold body in such manner as to be freely rotatable with respect to the manifold body about the central axis; providing a first offset port in the manifold body having a principal axis substantially orthogonal to the first axis of the manifold body such that the principal axis of the first offset port intersects the inner surface of the central ring at an angle; passing a fluid through the first offset port and against the inner surface of the central ring at an angle so as to impart rotary momentum to the central ring; passing at least a portion of the fluid passing through the first offset port between the inner and outer fluid diversion surfaces; and directing the portion of the fluid passing between the fluid diversion surfaces at the surface to be cleaned.
