Patent number: 10865653Abstract: A magnetic seal system adapted for use between a support structure and a rotatable shaft. The seal system includes a rotating annular seal assembly surrounding the shaft and rotating therewith, which includes an annular seal, and a non-rotating biasing assembly sealingly mounted to the support structure around the shaft and axially engaging the annular seal assembly. The biasing assembly includes an annular magnet unit axially displaceable relative to the shaft and supported surrounding the shaft. The annular magnet unit exerting an attracting force on the annular seal assembly to biasingly displace the annular magnet unit towards the annular seal. A bias member unit is also provided for non-magnetically biasing the annular magnet unit axially relative to the shaft towards the annular seal. Adjacent contacting surfaces between the annular seal and the annular magnet unit biasingly contact one another to form a sealing interface therebetween.Type: GrantFiled: March 18, 2016Date of Patent: December 15, 2020Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Julien De La Bruere Terreault, Dany Blais

Patent number: 10323530Abstract: A magnetic seal system adapted for use within a support structure mounted around a rotatable shaft. The magnetic seal system includes two annular seal assemblies configured to be surrounding the shaft to rotate therewith and be axially displaceable along the shaft. Each annular seal assembly includes an annular member adjacent to an annular seal. The magnetic seal system also includes an annular magnet configured to be sealingly connected to the support structure and surrounding the shaft The magnet being disposed between the two annular seals in a non-contacting relationship with the shaft and biasing the two annular members along the shaft towards the magnet, wherein adjacent contacting surfaces between each of the two annular seals and the magnet biasingly mate to form sealing interfaces.Type: GrantFiled: February 29, 2016Date of Patent: June 18, 2019Assignee: PRATT & WHITNEY CANADA CORP.Inventor: Julien De La Bruere Terreault

Patent number: 9791047Abstract: An assembly comprises a shaft, and a support structure surrounding the shaft; and a magnetic seal system comprising an annular seal assembly including a ring sealingly mounted to a shaft to rotate therewith and slidingly axially displaceable along the shaft, and an annular seal supported by the ring. An annular magnet assembly is configured to be non-rotatingly supported adjacent to and surrounding the shaft, the annular magnet assembly configured and positioned relative to the ring to exert a sufficient attracting force on the ring to biasingly displace the ring axially along the shaft into sealing contact with the magnet. A cooling fluid feeding conduit, a cooling fluid exhaust conduit distinct from the cooling fluid feeding conduit are provided.Type: GrantFiled: January 25, 2016Date of Patent: October 17, 2017Assignee: PRATT & WHITNEY CANADA CORP.Inventor: Julien De La Bruere Terreault

Patent number: 8337630Abstract: There is provided a method for cleaning the compressor of a gas turbine engine. The method comprises providing a fluid passage in the inlet case strut with a nozzle communicating with the fluid passage and the inlet gas path. The fluid passage has a fluid connector for connecting wash/rinse fluid under pressure to the fluid passage. The method further comprises motoring the gas turbine engine, and injecting, through the nozzle, the wash/rinse fluid into the inlet gas path to mix with an incoming flow of air and flow into compressor rotor blades of the compressor.Type: GrantFiled: July 18, 2012Date of Patent: December 25, 2012Assignee: Pratt & Whitney Canada Corp.Inventors: Julien de la Bruère-Terreault, Andrew Robert Marshall
