Rotary rinse nozzle for aircraft waste tanks.

摘要

A rinse nozzle for an aircraft waste tank includes a tubular member mountable at one end in an opening in the waste tank for receiving cleaning solution through said one end to the interior of the tubular member. The other end of the tubular member extends into the tank and is closed to prevent the exit of cleaning solution out that end. The tubular member has a midsection (32) with a reduced radius and a plurality of first openings (36) circumferentially spaced apart around the midsection. Ann annular collar (40) is rotatably disposed about the midsection of the tubular member and includes a plurality of second openings (64) disposed thereabout, at least some of which extend outwardly and rearwardly of the direction of rotation of the annular collar to thereby cause the collar to rotate as cleaning solution flows from the tubular member out the first openings against the collar and then out the second openings. A retainer ring (52) is positioned about the tubular member below the midsection to support and hold the collar on the tubular member about the midsection. <IMAGE>
