Abstract
A bearing assembly according to an example of the present disclosure includes, among other things, a bearing situated in a bearing compartment, a seal assembly that defines the bearing compartment, at least one deflector between the bearing and the seal assembly that is rotatable about an axis, and a coalescer at least partially extending about the at least one deflector to define a fluid passage. A method of sealing is also disclosed.
Claims21
A bearing assembly comprising:
- a bearing situated in a bearing compartment;
- a seal assembly defining the bearing compartment;
- at least one deflector between the bearing and the seal assembly that is rotatable about an axis;
- and
- a coalescer at least partially extending about the at least one deflector to define a fluid passage, wherein the coalescer includes a ring-shaped coalescer body that circumferentially extends about the deflector and is attached to a static structure, the at least one deflector includes a ring-shaped deflector body that radially opposes the coalescer body to define a radial gap along the fluid passage, and the deflector body is rotatable about the axis.
2 more elements
A gas turbine engine comprising:
- a fan section including a plurality of fan blades;
- a compressor section in fluid communication with the fan section;
- a turbine section driving the fan section or the compressor section through a rotatable shaft, the shaft rotatable about an engine longitudinal axis;
- and
- a bearing assembly supporting the shaft, comprising:
- a bearing situated in a bearing compartment;
- a seal assembly extending from a seal support, the seal support defining a trough extending from a floor, with an opening of the trough situated between the floor and the shaft;
- a deflector rotatable with the shaft and extending toward the trough;
- and
- a coalescer at least partially extending about the deflector to define a fluid passage, and wherein the coalescer includes a ring-shaped coalescer body that circumferentially extends about the deflector and is attached to a static structure;
- and
- wherein the deflector includes a ring-shaped deflector body that radially opposes the coalescer body to define a radial gap along the fluid passage, and the deflector body is rotatable about the engine longitudinal axis.
