Definitions

  • ABSTRACT A mechanical break-up spray nozzle comprises two members which define between them, by means of a channel in at least one of the members, a passage having one end closed and its opposite end communicating with an inlet cavity, an outlet orifice of the nozzle opening into the passage intermediate its ends and the crosssectional dimensions of the passage being small in relation to those of the inlet cavity.
  • a nozzle member is also provided which incorporates the inlet cavity, the groove and also the outlet orifice.
  • An object of the present invention is to provide a nozzle which can be moulded more easily and economically in large numbers, e.g., by injection moulding, and having predictable spray characteristics.
  • FIG. 1 is a front view of a first embodiment of nozzle
  • FIG. 5 shows a third embodiment similar to the preceding embodiments except that the groove 5 is in this case formed in the moulded valve stem 2, whilst there is no groove in the circularly cylindrical wall of the inlet cavity 4.
  • a nozzle as claimed in claim 8 wherein a projecting, curved, wall portion of said first member defines said groove.
