Abstract An oil tank is constructed having a perforated funnel therein. Oil scavenged from the engine is delivered by a tube to an opening in the small bottom of the perforated funnel. The delivery tube passes over the large elongated open top of the funnel acting as a cover means and deflector. As the oil passes through this funnel in a direction of increasing cross sectional area its velocity is reduced. Large air bubbles escape directly to the top of the funnel and smaller air bubbles are strained out as the oil passes through the perforations in the funnel. The oil then passes through a baffle device below the perforated funnel to a small compartment in the bottom of the tank. An outlet in this chamber directs deaerated oil to the engine main pressure pump. In some installations the top of the funnel could follow closely the shape of the tank at that point and even be attached to the tank, so that all oil would have to pass through the perforations.
A deaerating oil tank having a container with a deaerator therein, said deaerator being funnel shaped and perforated, the large part of the deaerator funnel shape being at the top and the small part of the funnel shape being at the bottom, air outlet means at the top of the container, oil outlet means at the bottom of the container, said container having an oil inlet which is connected to said small end of the funnel shape deaerator.

A deaerating oil tank having a container with a deaerator therein, said deaerator being funnel shaped and perforated, the large part of the deaerator funnel shape being at the top and the small part of the funnel shape being at the bottom, air outlet means at the top of the container, oil outlet means at the bottom of the container, said container having an oil inlet which is connected to said small end of the funnel shape deaerator.
Claim 3
Dependent Claim
30 words
A deaerating oil tank as set forth in claim 1 wherein cover means blocks a portion of the open large end of the funnel shape deaerator restricting oil flow therethrough.
Claim 4
Dependent Claim
22 words
A deaerating oil tank as set forth in claim 1 wherein a baffle means is located in the container adjacent the outlet.
Claim 5
Dependent Claim
58 words
A deaerating oil tank as set forth in claim 1 wherein the shape of the container is funnel shaped adjacent its bottom, the large part of the container funnel shape being approximately at the level of the small part of the deaerator funnel shape, a baffle means being located in the lower part of said container funnel shape.
Claim 6
Dependent Claim
41 words
