  • FOCUSING TUBE, AND USE THEREOF
    Publication number: 20230150089
    Abstract: A focusing tube is configured to focus a high-pressure liquid jet containing abrasive particles. The focusing tube has a focusing duct portion and an exit opening for the free discharge of the liquid jet from the focusing duct portion. A center point of the discharge opening coincides with the longitudinal axis of the focusing duct portion. The focusing duct portion is delimited by a liquid-impermeable channel wall, extends from the discharge opening at a focusing taper angle and is tapered toward the discharge opening. The focusing taper angle lies in a range from 0.05° to 1°. This allows the service life of the focusing tube to be increased in a way that is simple in terms of design.
