  • Patent number: 6676042
    Abstract: An airbag inflation nozzle assembly for fluidic mating with an inflation valve assembly, including an inflation valve stem, upon an inflatable cargo airbag comprises a housing, and an inflation nozzle member, having an inflation nozzle tip, pivotally mounted within the housing between a first position at which the inflation nozzle tip is fluidically disengaged from the inflation valve assembly, and a second position at which the inflation nozzle tip is fluidically engaged with the inflation valve assembly. A transversely oriented camming button is movably mounted upon the housing between an UNLOCKED position so as to permit the inflation nozzle member to be moved to the first fluidically disengaged position with respect to the valve assembly, and a LOCKED position which forces the inflation nozzle member to be moved to the second fluidically engaged position with respect to the valve assembly.

  • Patent number: 5125582
    Abstract: A surge enhanced cavitating jet for a fluid jetting system. The cavitating jet includes a nozzle portion having a conical throat followed by a fluid separating section. Immediately downstream from the separating section is a substantially cylindrical surge section. The length and inside diameter of the surge section are sized such that a minimum annular area is defined between the inside diameter of the surge section and the outside of the fluid stream as the fluid discharges from the cavitating jet such that cavitation is contained in the surge volume. The fluid stream does not impinge the inside diameter of the cavitating jet. A jetting system including a pump and valve is also disclosed.
