Patent number: 12055058Abstract: An assembly is provided for a gas turbine engine. This gas turbine engine assembly includes a case, a housing, a component and a spring element. The case includes an aperture that extends axially along an axis through the case. The housing is attached to the case with a cavity formed by and axially between the housing and the case. The component includes a base and a projection. The base is disposed within the cavity and axially engages the case. The projection projects out from the base and axially through the aperture. The spring element is disposed within the cavity. The spring element is compressed axially between and engages the base and the housing.Type: GrantFiled: May 31, 2022Date of Patent: August 6, 2024Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Michael Fryer, Martin Dobson, Oleg Iskra, Marc Lavoie, Ivan Sidorovich Paradiso, Louis Duranleau-Hendrickx, Domenico Di Florio

Patent number: 11852073Abstract: An orifice pack is provided for delivering pressurized air to a compressor bleed valve of a gas turbine engine. The orifice pack has a diffusion chamber in serial flow communication with a tapering passage and a first outlet passage for venting a first portion of the pressurized air from the diffusion chamber. A second outlet passage branches off from the diffusion chamber at an axial location between the inlet and the tapering passage. The second outlet passage is fluidly connected to the compressor bleed valve for directing a second portion of the pressurized air from the diffusion chamber to the compressor bleed valve.Type: GrantFiled: July 30, 2021Date of Patent: December 26, 2023Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Martin Dobson, Oleg Iskra, Michael Fryer, Marc Lavoie, Ivan Sidorovich Paradiso, Louis Duranleau-Hendrickx, Domenico Di Florio, Tibor Urac

Patent number: 11802509Abstract: Methods and systems for filtering pressurized air used to control a compressor bleed valve of a gas turbine engine are provided. One method comprises receiving the pressurized air in a conduit via an inlet of the conduit, releasing a first portion of the pressurized air out of the conduit via an outlet of the conduit, releasing a second portion of the pressurized air from the conduit via a port disposed between the inlet and the outlet of the conduit, directing the second portion of the pressurized air from the port to a filter along an upward flow path, filtering the second portion of the pressurized air using the filter, and directing the second portion of the pressurized air from the filter toward the compressor bleed valve.Type: GrantFiled: June 25, 2021Date of Patent: October 31, 2023Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Martin Dobson, Oleg Iskra, Michael Fryer, Marc Lavoie, Ivan Sidorovich Paradiso, Louis Duranleau-Hendrickx, Domenico Di Florio
