Title of Invention	AN INTEGRATED DE-AERATOR AND BREAHTER PUMP AND METHODS THEREOF
Abstract	The integrated de-aerator and breather pump comprises of a rotor and a static support. The outer casing which is the part of the rotor carries a porous member. The outer casing (70) has a first inlet at (121) for the scavenged air-oil mixture from the bearing chambers (364) and the Engine Gearbox (370) and second inlet at (122) for the vented/breathed air-oil mist from the bearing chambers through the Engine Gearbox. The rotor is supported on a static support (60) which is designed with passage for the scavenge oil (125), separated oil (127) and air (129). Oil from the air-oil mixture is separated in the porous member by the differential centrifugal force acting on the air and oil due to the difference in densities. The oil separated from the air-oil mixture is pumped back to the oil tank through the passage and the air is discharged out through. Fig. 3

Abstract

The integrated de-aerator and breather pump comprises of a rotor and a static support. The outer casing which is the part of the rotor carries a porous member. The outer casing (70) has a first inlet at (121) for the scavenged air-oil mixture from the bearing chambers (364) and the Engine Gearbox (370) and second inlet at (122) for the vented/breathed air-oil mist from the bearing chambers through the Engine Gearbox. The rotor is supported on a static support (60) which is designed with passage for the scavenge oil (125), separated oil (127) and air (129). Oil from the air-oil mixture is separated in the porous member by the differential centrifugal force acting on the air and oil due to the difference in densities. The oil separated from the air-oil mixture is pumped back to the oil tank through the passage and the air is discharged out through. Fig. 3

Full Text	FIELD OF THE INVENTION The present invention relates to an integrated de-aerator and breather pump unit. This invention is in particular related to a part of the lubrication system of a gas turbine used for military application.
