Abstract: A jet receiving receptacle is provided which is coupleable to a high-pressure fluid jet system opposite a nozzle thereof to receive a fluid jet discharged from the nozzle after it acts on a workpiece. The jet receiving receptacle may include an elongated inlet alignable with a direction of travel of the nozzle to receive the fluid jet in a deflected state. The jet receiving receptacle may further include a jet deflection device positioned downstream of the elongated inlet to redirect at least a portion of the fluid jet and a jet rebound device located upstream of the jet deflection device to be impinged on by the redirected portion of the fluid jet. The jet deflection device and jet rebound device may form, in combination with a housing, a device to trap the fluid jet. Fluid jet cutting systems incorporating a jet receiving receptacle and related methods are also provided.
