Abstract

The present invention relates to a nozzle for an air trapping device configured to remove air from a fluid, the nozzle comprising a body having an input opening configured to receive the fluid and an output opening configured to distribute the fluid along an edge of the output opening, wherein the edge comprises a control element configured to reduce surface tension of the fluid. The present invention further relates to an air trapping device 200 configured to remove air from a fluid and comprising the nozzle.

First claim

The invention claimed is:

1. An air trapping device configured to remove air from a fluid, the air trapping device comprising:
a receptacle configured to hold the fluid, the receptacle comprising:
a nozzle, the nozzle comprising body having an input opening configured to receive the fluid and an output opening configured to distribute the fluid along an edge of the output opening, wherein the edge comprises a control element configured to reduce surface tension of the fluid,
a lid section,
a drainage section comprising a fluid outlet and a fluid inlet, and
a tubular section interconnecting the lid section with the drainage section;

a feeder element comprising a tubular element coupled to the input opening of the body of the nozzle and being further coupled to a fluid inlet of the air trapping device; and
a guiding element coupled to the body of the nozzle and configured to guide the fluid distributed along the edge of the output opening in a direction of gravity along a surface of the guiding element,
wherein the output opening of the nozzle is located in a top quarter of the tubular section,
wherein the body of the nozzle has a funnel shape and an input opening being smaller than the output opening,
wherein the control element is formed as one of a sine shape, a square shape, an edge with slits or an edge with a plurality of holes, and
wherein the guiding element comprises a tubular element coupled to the input opening of the body of the nozzle.

2. The device according to claim 1 , wherein the nozzle comprises a guiding element having a cross section which have an area less than 1/10 of an area of a cross section of the tubular section.

3. The device according to claim 1 , wherein the drainage section comprises a plurality of openings facing the tubular section, each opening being coupled to the fluid outlet.

4. The device according to claim 1 , wherein the drainage section is configured as having a funnel shape and having an opening facing the tubular section and being coupled to the fluid outlet.

5. The device according to claim 1 , wherein the tubular section comprises an annular bulge.

6. The device according to claim 1 , wherein the device is configured to be operated when oriented with the lid section in a direction opposite to the direction of gravity.
