ABSTRACT:
A jet thruster for attachment to the outlet end of a high-liquid-pressure hose for use, among other things, in clearing drain lines or the like. The jet thruster comprises a body formed of at least hemi-spherical shape about a fore-and-aft axis that is substantially an extension of the hose. The hemi-spherical shape gives the frontal area of rearwardly and radially outwardly sloping configuration over which liquid jets stream in close proximity to that area to augment the forward thrust action against the walls of the drain line which facilitates advance of the thruster through the drain line. Ahead of the frontal area a spinner head is coaxially journalled for rotation via thrust exerted by liquid existing laterally from another jet in the spinner head. The spinner head jet(s) further create forces that are utilized for clearing the drain line of sludge, roots and the like. Further, the spinner head may carry blades or the like for increasing the clearing action of the thruster.
