ABSTRACT:
An apparatus for pressurized cleaning of flow conductors. The apparatus utilizes a control slot formed in a zig-zag pattern and a pin which travels in the slot. The slot and pin assist in indexingly rotating the nozzle section of the apparatus when the apparatus is reciprocated in alternate directions in the flow conductor. Pressurized cleaning fluid is supplied to the apparatus and is directed radially outward through nozzles against the flow conductor in such a manner as to progressively clean the flow conductor as the nozzle section rotatively indexes. Another set of nozzles may be included, if desired, in the lower end of the apparatus to allow cleaning along the longitudinal axis.
