Abstract
A rotatable high pressure tool for cleaning hollow objects by forcing a high pressure fluid such as water from nozzles to create cleaning jet streams and use jet reaction at the tool to continually change the direction of the jet nozzles about a longitudinal axis of the tool while the jets are carried by a cross body rotating about an axis essentially perpendicular to the longitudinal axis. Each of the nozzles provides the same amount of reaction torque to rotate the cross body about its axis. This torque is selectively adjustable at the tool before use by similarly releasing, changing and reclamping the orientation of all nozzles relative to the cross body and by changing the discharge diameters of uniformly sized nozzle tips. The adjustable nozzles are interconnected by gearing so that the changes in orientation of all nozzles during adjustment will be the same. The rotational speed of the nozzles and main body during use are further controlled by being subjected to a torque drag of a viscous liquid between two closely spaced surfaces.
