Estimating the term…
The deaerator includes a chamber that includes vortex generators that centrifuge the oil/air to separate the components and the chamber may operate in all attitudes. In addition wake separators mounted in the inlet of the chamber remove a large percentage of the air from the oil prior to entering the chamber and reintroduce the separated air component in the air removal tube. A dam in the air removal tube is located downstream of the inlet of the wake separated air to assure no oil is extracted from the air tube leaving the chamber. The wake separator consists of one or more tubes extending transversely to the flow of the oil/air stream and the air is removed through rearwardly facing apertures formed in the tube(s).
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.
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.
