Abstract
Apparatus for cleaning an internal passage of an article, such as a fuel passage of a gas turbine or other engine. The apparatus comprises a container for containing cleaning fluid, means for communicating a first end of the passage to the cleaning fluid in the container, and cleaning fluid conduit means communicated to a second end of the passage in a manner to draw cleaning fluid from the container to flow through the passage from the first end toward the second end in response to flow of cleaning fluid through the conduit means. The apparatus includes means for blocking flow of cleaning fluid through the conduit means so as to direct the cleaning fluid therein to flow through the passage from the second end toward the first end and into the container.
