Patent ID: 7497224

Claim:
An apparatus for dispensing a liquid under pressure for cleaning a surface in an enclosure, the apparatus comprising: at least one nozzle for dispensing a liquid under pressure; a conduit that extends horizontally beyond a stationary sled supporting the conduit so as to provide a cantilevered end of the conduit, the conduit having a passage therein for communicating a liquid under pressure to the at least one nozzle disposed at the cantilevered end of the conduit, for enabling the at least one nozzle to be extended through an opening in an enclosure to permit dispensing a liquid under pressure within the enclosure; a stationary sled that provides support for the conduit; an actuator for selectively rotating the conduit about its longitudinal axis at a desired rate, such that the at least one nozzle on the cantilevered end of the conduit may discharge a liquid under pressure 360 degrees about the axis of the conduit at the cantilevered end for cleaning interior surfaces within the enclosure; a barrel surrounding at least part of the length of conduit, which rotates within the barrel, wherein the inner diameter of the barrel surrounding the conduit defines a space between the conduit and barrel in which a coolant is received for conducting heat away from the barrel and conduit, which may be absorbed from heat being radiated within the enclosure, said barrel including a suspension support thereon, for reducing the amount of deflection in the cantilevered conduit and length of barrel surrounding the conduit such that the cantilevered end of conduit may be leveled for aligning the at least one nozzle to enable discharge of a stream of liquid under pressure 360 degrees within a generally vertical plane; a linear displacement device that comprises a trolley that is movable along a length of track, being configured to controllably move the conduit for extending the cantilevered end of the conduit and the at least one nozzle through an opening in an enclosure for dispensing a liquid under pressure therein; and an adjustable support member that supports at least a portion of the conduit opposite the cantilevered end having the at least one nozzle, wherein the adjustable support member comprises a pivotal support mounted to the trolley that pivotally raises the conduit though application of pressure to a cylinder, so as to substantially align the at least one nozzle to discharge a stream of liquid under pressure within a generally vertical plane.
