Patent ID: 7682466

Claim:
An apparatus for dispensing a liquid under pressure for cleaning a surface in an enclosure, the apparatus comprising: a conduit having first and second ends, and a passage therein extending to the first end for communicating a liquid under pressure to the first end; at least one nozzle disposed on the second end of said conduit, for dispensing said liquid under pressure within the passage of said conduit; a stationary sled configured to be positioned outside of an enclosure for supporting a portion of the conduit while permitting movement of the conduit relative to the stationary sled, such that the second end of the conduit extends horizontally beyond the stationary sled, and the second end of the conduit that extends beyond the stationary sled is unsupported so as to provide a 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, wherein the stationary sled is adjustable for raising and lowering the portion of the conduit supported by the stationary sled; and an adjustable support member that supports the first end portion of the conduit, the adjustable support member being configured to pivot to adjustably raise or lower the first end portion of the conduit for aligning the cantilevered end of the conduit so as to substantially align the at least one nozzle on the second end of the conduit to discharge a stream of liquid under pressure within a generally vertical plane, wherein the cantilevered end of the conduit is configured to extend through an opening in an enclosure, with the conduit being supported only by the adjustable support and the stationary support configured to be positioned outside the enclosure; a linear displacement device configured to controllable move the conduit to extend the at least one nozzle on the cantilevered second end of the conduit through and opening in an enclosure for dispensing a liquid under pressure therein.
