Abstract

An improved rinse nozzle apparatus is described which is mounted on an aircraft waste tank and functions to efficiently rinse the interior of the waste tank when the tank is emptied and cleaned. The rinse nozzle includes a plastic body mounted on the tank. A stainless steel hose connect nipple is molded into the body at a first end of a liquid passageway which is provided therethrough. A plurality of brass rinse jets are also molded into the body. The rinse jets disperse and direct the cleaning solution against the inside of the waste tank. By fabricating the rinse nozzle mostly from light-weight plastic and molding the metal hose connection nipple and rinse jets into the plastic body, a lighter weight, leak free, and less expensive rinse nozzle is provided.

Claims

1. A rinse nozzle for mounting in an aircraft waste tank to communicate a liquid from the outside of the tank to the interior of the tank, said nozzle comprising:

a body, the body being comprised of a polymeric material;

a liquid passageway provided through the body;

a hose connect nipple provided at a first end of the liquid passageway and molded into the body, the hose connect nipple capable of being connected to a hose carrying a liquid under pressure, the hose connect nipple comprised of a material different than the polymeric material; and

a plurality of rinse jets attached to the body and in communication with the passageway, the rinse jets comprised of a material different than the polymeric material, such that liquid can be forced through the passageway and into the interior of the waste tank to clean waste therefrom.

2. A rinse nozzle for mounting in an aircraft waste tank as defined in claim 1 wherein the rinse jets do not substantially protrude from the surface of the body.

3. A rinse nozzle for mounting in an aircraft waste tank as defined in claim 1 wherein the rinse jets are molded into the body.

4. A rinse nozzle for mounting in an aircraft waste tank as defined in claim 1 wherein the liquid is a cleaning solution.

5. A rinse nozzle for mounting in an aircraft waste tank as defined in claim 1 wherein the hose connect nipple is fabricated from a metal.

6. A rinse nozzle for mounting in an aircraft waste tank as defined in claim 1 wherein the polymeric material comprises nylon.

7. A rinse nozzle for mounting in an aircraft waste tank as defined in claim 1 wherein the polymeric material comprises nylon and the hose connect nipple and the rinse jets each are fabricated from a metal.

8. An apparatus for holding human waste on an aircraft comprising:

a tank capable of being mounted on an aircraft, the tank having an inlet for receiving waste liquids ;

a sensor mounted on the tank, the sensor adapted for detecting the level of the waste in the tank;

a rinse nozzle body mounted on the tank, the rinse nozzle body being comprised of a polymeric material;

a liquid passageway provided through the rinse nozzle body;

a hose connect nipple provided at a first end of the liquid passageway and molded into the body, the hose connect nipple capable of being connected to a hose carrying a liquid under pressure, the hose connect nipple comprised of a material different than the polymeric material; and

a plurality of rinse jets attached to the body and in communication with the passageway, the rinse jets comprised of a material which is different from the polymeric material, the plurality of rinse jets being oriented such that the liquid can be forced through the passageway and onto the interior of the waste tank such that waste clinging to the interior of the tank can be dislodged.

9. An apparatus for holding waste on an aircraft as defined in claim 8 wherein the rinse jets are oriented such that a stream of the liquid is directed against the sensor.

10. An apparatus for holding waste on an aircraft as defined in claim 8 wherein the rinse jets do not substantially protrude from the surface of the body.

11. An apparatus for holding waste on an aircraft as defined in claim 8 wherein the rinse jets are molded into the body.

12. An apparatus for holding waste on an aircraft as defined in claim 11 wherein the liquid is a cleaning solution.

13. An apparatus for holding waste on an aircraft as defined in claim 12 wherein the hose connect nipple is fabricated from a metal.

14. An apparatus for holding waste on an aircraft as defined in claim 13 wherein the polymeric material comprises nylon.
