Patent ID: 6977015

Claim:
A method for cleaning internal channels in an article, said method comprising: providing an article, said article comprising at least one internal channel comprising at least one inlet port and at least one outlet port; providing a cleaning apparatus, said apparatus comprising a cleaning fluid, a reservoir containing said cleaning fluid, said reservoir comprising an interface shaped to allow a fluid-tight connection between said reservoir and said article, said interface comprising an orifice to allow fluid communication between said reservoir and said at least one internal channel of said article, said reservoir further comprising a cleaning fluid inlet connected to a source of said cleaning fluid, and a cleaning fluid outlet to expel excess cleaning fluid; a transmitter of vibrational energy projecting into said reservoir, said transmitter comprising a transmitter tip, and a source of vibrational energy coupled to said transmitter, said vibrational energy comprising a frequency and a wavelength; attaching said article to said apparatus at said interface; and flowing said cleaning fluid from said fluid source through said reservoir and said at least one internal channel of said article, and out through said cleaning fluid outlet; and transmitting vibrational energy from said source of vibrational energy through said transmitter to said article.
