SEAL ASSEMBLY FOR A TURBOMACHINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18196949 titled 'SEAL ASSEMBLY FOR A TURBOMACHINE
Simplified Explanation
- The patent application is for seal assemblies used in turbomachines. - The seal assemblies consist of stationary and rotating components with at least one interface between them. - A self-lubricating lattice element made of carbon or a carbon-based material is included in the seal assembly. - The self-lubricating lattice element has a porous and compressible microstructure that can retain a liquid substance. - During engine operation, the self-lubricating lattice element can compress and expel some of the liquid substance. - This forms a layer of liquid between the rotating and stationary components of the seal assembly. - The patent application also describes self-lubricating wear sleeves for other parts of the turbomachine.
Original Abstract Submitted
This disclosure is directed to seal assemblies for a turbomachine. The seal assemblies include stationary and rotating components and at least one interface between the stationary and rotating components. The seal assembly further includes a self-lubricating lattice element made of carbon or a carbon-based material. The self-lubricating lattice element may have a porous and compressible microstructure capable of retaining a liquid substance. During engine operation, the self-lubricating lattice element can compress and expel some portion of the liquid substance to form a liquid-containing layer between the rotating and stationary components of the seal assembly. Also described herein are self-lubricating wear sleeves for use in other portions of the turbomachine.
