Abstract:
A nozzle assembly for enlarging an inground passageway produced by, for example, a boring device is disclosed herein. The nozzle assembly is comprised of a longitudinally extending nozzle body defining an interior cavity adapted to receive fluid under pressure from an external source and at least one arrangement of outwardly facing adjacent stepped surfaces which provide longitudinally spaced cutting jets directed normal to the movement of the boring device and nozzle assembly as the latter moves through a previously provided passageway in order to progressively enlarge the passageway.
