Abstract: The present invention provides a flow insert and improved flow tube, such as a nozzle, that divides flow by generating an interrupted flow pattern, including pressure/energy gradients, in the otherwise uninterrupted flow of high pressure water through the nozzle. Cutting, cleaning, and boring performance is substantially improved. The interrupted flow pattern can provide for egress of cut or broken material to get out of the way, so cutting or cleaning action is not hampered by a continuous flow of high-pressure water. One or more balls circumferentially rotating around a ball-track assembly having a track support within the flow tube causes the flow interruption. When the flow is interrupted, the interruption's trailing edge (that is, the flow's restarting edge after the interruption) provides stronger cutting action than a continuous solid jet. The flow tube can be used for a broad array of industrial cleaning, surface preparation, cutting, and boring/drilling applications.

Abstract: A fluid system has a lengthwise axis, a chord length, a first body portion, a second body portion, a spacer, and a fluid pressurizer.

The fluid pressurizer is disposed within the channel cooperatively defined by the first body portion and the second body portion. The first body portion defines a cavity that is sized and configured to filter debris that enters the channel during use and provide a mechanism for removing the debris from the system.

Abstract: As shown for example in FIG. (5), the strainer (13) has a body (2) that defines a plurality of inlet holes (3). Each of the inlet holes (3) is in fluid communication with a hollow internal chamber. In use, liquid is sucked through the holes (3), thereby straining out larger contaminants such as rocks and stones, into the hollow internal chamber and then out the outlet. The majority of the strainer (13), is formed from a resilient deformable material that allows opposed sides of the internal chamber to be brought into contact with each other in response to the application of a compressive force. Once the force is no longer being applied, the resilience of the material allows the body (2) to resiliently return to substantially its pre-deformation shape.
