Claims
- 1. A deaerator apparatus for removing air entrained in oil having wall means for defining an enclosed chamber and vortex generating means in said chamber, the air entrained in oil being an air/oil mixture being centrifuged by said vortex generating means to separate the oil and air from the air/oil mixture, an inlet formed in said wall means for admitting the air/oil mixture into said enclosed chamber wherein the oil is directed toward the wall means of said enclosed chamber, an air removal tube extending through said wall means into said enclosed chamber for removing the air, wake separator means disposed in said inlet for creating a wake and removing a portion of the air from said air/oil mixture prior to said air/oil mixture entering said enclosed chamber, and connecting means interconnecting said wake separator means and said air removal tube.
- 2. A deaerator apparatus for removing air entrained in oil as claimed in claim 1 wherein said wake separator means includes a tubular member closed at one end extending into said inlet, said tubular member being disposed transversely relative to the flow of the air/oil mixture in said inlet, a plurality of apertures axially spaced on the downstream side of said tubular member relative to the direction of flow of said air/oil mixture.
- 3. A deaerator apparatus for removing air entrained in oil as claimed in claim 1 wherein said wake separator means includes a plurality of tubular members extending in said inlet defining a predetermined pattern of spacing, a plurality of apertures extending axially on the downstream side of each of said tubular members relative to the direction of flow in said inlet, connection means interconnecting said tubular members and said air removal tube, said connection means including a conduit for each tubular member each having an outlet oriented with respect to said air removal tube such that the air component is discharged tangentially and each outlet is spaced circumferentially around said air removal tube.
- 4. A deaerator apparatus for removing air entrained in oil as claimed in claim 3 wherein said tubular member is closed on one end and opened on the opposite end, and said one end being disposed in said inlet.
- 5. A deaerator apparatus for removing air entrained in oil as claimed in claim 4 including dam means in said air removal tube disposed downstream of said outlets relative to the flow of air in said air removal tube.
- 6. A deaerator apparatus for removing air entrained in oil as claimed in claim 5 wherein said dam means is toroidally shaped and the opening of the toroidal shape is coaxially disposed relative to the longitudinal axis of the air removal tube.
- 7. A deaerator apparatus for removing air entrained in oil as claimed in claim 1 wherein said wake separating means includes a plurality of tubular members laterally disposed in said inlet relative to the flow of the air/oil mixture in said inlet, a plurality of apertures spaced axially formed on the downstream side of each of said tubular members relative to the flow of the air/oil mixture in said inlet, and connecting means interconnecting said tubular member and said chamber.
- 8. A deaerator apparatus for removing air entrained in oil as claimed in claim 7 wherein said connecting means includes a conduit connected to each of said tubular members, each of said conduits including an outlet disposed circumferentially in said chamber, and each outlet oriented to flow the air discharging therethrough tangentially and in a direction of the centrifuged air in said chamber.
- 9. Wake separator means for creating a wake and removing a portion of the air from an air/oil mixture, conduit means for flowing the air/oil mixture from one location to another location, an air vent for removing the air component from said conduit, connecting means interconnecting said wake separator means and said air vent, said wake separator means including at least one tubular member closed at one end extending into said conduit, said tubular member being disposed transversely relative to the flow of the air/oil mixture in said conduit, a plurality of apertures axially spaced on the downstream side of said tubular member relative to the direction of flow of said air/oil mixture.
