Definitions

  • This invention relates to a rinse nozzle for more uniform cleaning of the inside of aircraft waste tanks and the like.
  • a spray nozzle which includes a tubular stem, one end of which may be mounted in an opening in an aircraft waste tank so that the other end projects into the waste tank.
  • Said one end of the tubular stem is open to receive cleaning solution or water thereinto, while the other end is closed to prevent the exit of such cleaning solution or water.
  • a multiplicity of openings are formed at a midsection of the stem and are circumferentially spaced apart around the midsection.
  • An annular collar is rotatably positioned about the midsection of the stem so that cleaning solution or water exiting the openings formed in the midsection strike an interior wall of the collar.
  • Openings are formed in the collar to allow the exit and spraying of water or cleaning solution outwardly of the collar. At least some of the collar openings are directed outwardly and in a direction generally opposite that in which the collar rotates. As water or cleaning solution exits from such openings, the collar is caused to rotate and thereby throw the spray uniformly in all directions against the inside walls of the tank.
  • a mounting ring is positioned about the stem below the midsection thereof to hold the annular collar on the stem.
  • FIG. 1 is a side, partially fragmented view of an aircraft waste tank with the nozzle of the present invention mounted therein;
  • FIG. 2 is a side, elevational, partially cross-sectional view of a rotary nozzle made in accordance with the principles of the present invention.
  • FIG. 1 there is shown a fragmented view of an aircraft waste tank 4 into which waste products from passengers and aircraft personnel are delivered via a conduit 8.
  • Another conduit 10 is fitted in a cap 11 to allow escape of air as the tank 4 fills, and also to allow for producing a vacuum in the tank to aid in drawing waste products into the tank.
  • Mounted on an upper sidewall 4a of the tank is a rotating rinse nozzle assembly 12 made in accordance with the principles of the present invention.
  • a conduit 16 is coupled to the assembly 12 to deliver water or other cleaning solution thereto and the assembly uniformly disperses the water or solution under pressure to the inside walls of the tank 4.
  • the nozzle assembly 12 might illustratively be mounted in the sidewall 4a of the tank by screwing it into a threaded opening, by disposing the assembly in an opening and securing it with an adhesive, by using a variety of mounting brackets known in the industry for mounting nozzles and similar articles, etc.
  • FIG. 2 shows a side, partially cross-sectional elevational view of the rotating rinse nozzle assembly 12 of FIG. 1.
  • the nozzle includes a tubular stem 20 open at an upper end 20a and closed at the other end 20b.
  • the upper open end 20a includes threads 24 on the exterior surface thereof to enable screwing the assembly into a threaded opening of an aircraft waste tank.
  • a n enlarged shoulder section 28 is formed just below the threads 24, as shown, to provide an abutment and stop for the assembly when it is inserted into an opening of the tank.
  • Spaced below the shoulder section 28 is a midsection 32 having a reduced circumference from the remainder of the stem 20. Those portions of the stem 20 just above and below the midsection 32 have substantially the same circumference, as indicated in FIG. 2.
  • a plurality of openings 36 are formed in the midsection 32 to allow the exit of water or cleaning solution delivered to the interior of the stem 20.
  • the openings 36 are circumferentially spaced apart about the midsection so as to direct water or cleaning solution radially outwardly from the midsection.
  • An annular collar or ball 40 (shown in side cross-section mounted on the stem 20 in FIG. 2 and also shown to the right of the stem in a full side view) is rotatably mounted on the stem so that upper and lower lips 44 and 48 are in sliding contact with those portions of the stem just above and below the midsection 32.
  • a mounting or retaining ring 52 with interior threads, is screwed out of the lower threaded end 20b of the stem 20 to retain the collar 40 in place about the stem.
  • mounting ring 52 would be to form the interior surface of the ring with a groove and form the exterior of the lower portion of the stem 20 with an oppositely positioned groove.
  • a ring seal would be positioned in the two grooves to fill the space therebetween and hold the mounting ring 52 in position.
  • Still another embodiment of the nozzle assembly 12 would be to replace the shoulder section 28 with a threaded ring for screwing onto the upper end 20b of the stem 20, and to rigidly form the mounting ring 52 as part of the lower end 20b of the stem.
  • the collar 40 would simply be slipped over the upper end 20a of the stem until it rests on the ring 52, the ring 28 would next be screwed onto threads 24 to a position just above the collar, and then the upper end 20a of the stem would be screwed into the threaded opening in the aircraft waste tank.
  • the stem 20, collar 40 and mounting ring 52 are made of polytetrafluoroethylene.
  • the collar 40 is formed with a plurality of circumferentially positioned openings 64 at least some of which are directed outwardly and in a direction opposite the direction of rotation of the collar.
  • openings 64a are illustrated in FIG. 2 in which the arrows associated with the openings indicate the direction in which the openings are formed. Since the arrows are shown directed to the right, the collar 40 would be caused to rotate in a direction to the left. [Clockwise if looking down on the top of the collar.]
  • Other of the openings 64 are formed to be directed outwardly and either downwardly or upwardly, as indicated by the arrows in FIG. 2.
  • the collar 40 is caused to rotate in a direction determined, for example, by the openings 64a when water or cleaning solution supplied to the stem 20 flows through openings 36 and then out of the openings 64. Because the water or cleaning solution would be directed outwardly and in a first direction from the collar 40, the collar would be caused to rotate in a second direction opposite the first direction. Water or cleaning solution would also be flowing or spraying through the other openings 64 in the collar 40 and this would be sprayed throughout the interior of the waste tank 40 of FIG. 1.
