ABSTRACT:
A rotary jetting tool including a pressure-balanced rotor, which is achieved using a vented volume. Axial movement of the rotor relative to the housing caused by pressure imbalances acting on the rotor selectively uncovers or opens a vent that places the volume in fluid communication with an ambient volume, enabling the rotor to achieve a pressure balanced condition. A plurality of radial clearance seals between the rotor and the housing are used to provide hydrodynamic bearings to reduce friction between the rotor and housing. The diameters of the seals are manipulated to facilitate pressure balancing of the rotor. In one embodiment, the rotor includes a centrifugal brake configured to control a maximum rotational speed of the rotor. Pressurized fluid is introduced into the rotor in an axial direction, enabling a relatively large upstream settling chamber to be incorporated into the rotor, thereby reducing inlet turbulence and improving jet quality.
