Abstract

A water injector for an aviation cooling system includes a body having a first end, a second end, and an intermediate portion extending therebetween. A conduit extends through the body from the first end to the second end. A spray nozzle is fluidically connected to the conduit and arranged at one of the first end and the second end. A mounting plate is arranged at the other of the first end and the second end. The mounting plate is configured and disposed to secure the body to an aviation cooling component. A filter is supported at the body and is fluidically exposed to the conduit. The filter is configured and disposed to capture particulate flowing into the water injector towards the spray nozzle.

First claim

What is claimed is:

1. A water injector for an aviation cooling system comprising:
a body having a first end, a second end longitudinally spaced along a longitudinal axis from the first end, and an intermediate portion extending therebetween, the intermediate portion extending longitudinally along the longitudinal axis;
a conduit extending along the longitudinal axis through the body from the first end to the second end;
a spray nozzle fluidically connected to the conduit arranged at one of the first end and the second end, the spray nozzle extending along the longitudinal axis and being threadingly connected to the body in a repeatedly removable manner;
a mounting plate arranged at the other of the first end and the second end, the mounting plate being extending substantially perpendicularly to the longitudinal axis and being configured and disposed to secure the body to an aviation cooling component; and
a filter supported in a filter body at the body and fluidically exposed to the conduit, the filter being configured and disposed to capture particulate flowing into the water injector towards the spray nozzle, the filter body extending along the longitudinal axis and being threadingly engaged in the other of the first end and the second end in a repeatedly removable manner.

2. The water injector according to claim 1 , wherein the spray nozzle includes an orifice having an outlet of less than about 0.120-inches (3.05-mm).

3. The water injector according to claim 1 , further comprising: a sealing gasket arranged at the mounting plate, the sealing gasket being configured and disposed to seal an interface between the water injector and the aviation cooling component.

4. The water injector of claim 1 , wherein the mounting plate includes a sealing gasket on a side of the mounting plate that faces the one of the first end and the second end.

5. The water injector of claim 1 , wherein the filter body includes a threaded end, an outlet longitudinally aligned along the longitudinal axis with the threaded end and an inlet end at an opposing end, the inlet end configured to connect with a fluid line to collect water from a water collector.

6. The water injector of claim 5 , wherein the threaded end of the filter body is longitudinally aligned along the longitudinal axis with the mounting plate.
