|20120276818||MULTI-JET NOZZLE - Some embodiments can be implemented as a system, method, or nozzle and can include some of these features. A fluid jet cutting system can include a frame, a cutting head, a high-pressure fluid source, an abrasive source, and an actuator. The cutting head can include a fluid inlet, an orifice, a mixing chamber, and a fluid jet nozzle. The fluid jet nozzle can include an elongated body which can include a body axis, a fluid inlet orifice that can be in fluid communication with a plurality of conduits, and a source of high speed fluid and abrasive, which can be the cutting head's mixing chamber. Each of the plurality of conduits can: be in fluid communication with the fluid inlet orifice; have its own conduit axis that forms an angle with the body axis; and be in fluid communication with its own fluid outlet orifice.||11-01-2012|
|20100210186||MULTI-HEAD FLUID JET CUTTING SYSTEM - Embodiments of the invention provide multi-head fluid jet cutting systems and methods of utilizing such devices. A multi-head fluid jet cutting system includes a body having a plurality of fluid jet cutting heads installed therein. Each cutting head receives pressurized fluid from an intensifier and directs the fluid along a jet axis out of a nozzle of the head to form a cutting stream. In some embodiments, an abrasive material can be mixed with the fluid to form an abrasive fluid cutting stream. The body can be mounted to a motion system which moves the body, and therefore the cutting heads, relative to a work piece mounted upon a work bed. Each of the fluid jet cutting heads is coupled to an actuator which can control an on/off state of the cutting head. In some embodiments, an actuator mounting plate is provided to enable mounting of the actuators off of the jet axes.||08-19-2010|
