  • Method for removing viscoelastic contaminants from holes
    Patent number: 5366562
    Abstract: The invention relates to a method for the removal of viscoelastic rubber residues from deep holes. The cleaning tool is suggested in the form of a jet of fluid droplets. The fluid is accelerated by a high-pressure pump and a narrow valve to a velocity above the speed of sound of the material to be removed. The distance between the valve and the hole to be cleaned is made greater as the valve cross-section is made smaller in relation to the cross-section of the hole to be cleaned.
