摘要： A fluid jet system for achieving a kerf width less than 0.015 inches is provided. In one embodiment, the system includes an orifice mount having a high pressure fluid bore and an abrasive bore configured to communicate an abrasive mixture in form of a paste or foam to at least a portion of the high-pressure fluid bore. The system further includes a pressure-generating bore and a thin kerf mixing tube respectively provided toward opposing longitudinal ends of the mount body, minimizing a distance therebetween. A method of in-situ recycling of abrasives in the high-pressure fluid jet system includes catching the exiting abrasive-fluid mixture in a catching device, filtering the mixture in a filtering device, and directly pumping the filtered abrasive-fluid mixture to the mixing area without requiring conditioning of the mixture to remove liquids.

摘要： A hydraulic machine includes first and second opposing motors. Displacement of the first and second motors is controlled such that while the sum of the displacements of the first and second motors is below a threshold, the displacement of the first motor is substantially equal to the sum, and the displacement of the second motor is substantially equal to zero. While the sum of the displacements is above the threshold, the displacement of the first motor may be substantially equal to the displacement of the second motor, either as a displacement percentage or as a displacement volume. The first motor may be equal in capacity, or smaller than the second motor.

摘要： A turbocharger system (30) includes first (25) and second turbines (27) arranged such that exhaust gas passes through the first turbine (25) then the second turbine (27). A bypass channel (23) is configured such that exhaust gas entering the channel passes only through the second turbine (27). A valve (24, 34, 60, 66, 70) positioned in the bypass channel (23) regulates the flow of gas therethrough. The valve (24, 34, 60, 66, 70) accelerates a stream of gas and focuses the stream toward the second turbine (27) such that a large part of the added velocity of the stream is preserved as it enters the second turbine (27). Operation of the valve (24, 34, 60, 66, 70) may be controlled so as to maintain the valve in a closed position while exhaust gas pressure above the first turbine pressure (25) is below a first threshold, to progressively open the valve (24, 34, 60, 66, 70) as the pressure (25) increases above the first threshold, and to maintain the valve (24, 34, 60, 66, 70) in a full-open position while the pressure is above a second threshold.

摘要： A cover device is provided for a jet receiving receptacle of a highpressure fluid jet system to assist in receiving and in some instances, capturing, a fluid jet discharged from a nozzle of the fluid jet system after it acts on a workpiece. The cover device assists in preventing damage to a workpiece by deflecting a rebounding portion of the jet fluid away from the workpiece, and may also assist in reducing noise levels during workpiece processing operations. Fluid jet cutting systems incorporating a jet receiving receptacle with a receptacle cover and related methods are also provided. A capturing system including a material displacement device with a rebound surface to deflect a portion of rebounding contents of the fluid away from the workpiece is also proposed.
