ABSTRACT:
A rotary spray nozzle directional tank cleaning machine has a first, stationary housing, a second housing mounted to the first housing for rotation about a first, typically vertical axis, and a third housing mounted to the second housing for rotation about a second axis. The second axis is at a first, acute angle to the first axis. The second housing is driven about the first housing through an impeller driven gear train by the pressurized cleaning liquid passing therethrough. The third housing is driven by a pair of bevel gears mounted to the first and third housings. One or more nozzles, mounted to the third housing, direct cleaning liquid along a third axis oriented at a second, acute angle to the second axis. The first and second, acute angles are preferably 45.degree. to create a hemispherical spray pattern.
