Patent number: 11110406Abstract: A method for causing exhaust gas flow to flow at least 270 degrees in a first direction about a perforated tube using a baffle plate having a main body with a plurality of flow-through openings and a plurality of louvers positioned adjacent to the flow-through openings. The method includes deflecting a first portion of the exhaust gas flow with the main body of the baffle plate. The method also includes allowing a second portion of the exhaust gas flow to flow through the flow-through openings of the baffle plate. The method also deflects the second portion of the exhaust gas flow at a downstream side of the main body with the louvers hereby causing the second portion of the exhaust gas flow to flow in the first direction about the perforated tube.Type: GrantFiled: March 20, 2020Date of Patent: September 7, 2021Assignee: Donaldson Company, Inc.Inventors: Korneel De Rudder, Stéphane Le Merdy

Patent number: 9810126Abstract: An exhaust treatment system includes an exhaust conduit for conveying exhaust gases from an engine of a vehicle. An aftertreatment device is disposed in the exhaust conduit. A flow device is disposed upstream of the aftertreatment device. The flow device includes a base having a first surface and an oppositely disposed second surface. The base defines a plurality of openings. A plurality of flow deflectors is engaged to the base at the plurality of openings. Each flow deflector includes a first deflector that extends outwardly from the first surface of the base and a second deflector that extends outwardly from the second surface of the base. The first and second deflectors define a passage. Flow of exhaust gases through the passage cause exhaust gases to swirl about a longitudinal axis of the exhaust conduit.Type: GrantFiled: September 24, 2013Date of Patent: November 7, 2017Assignee: DONALDSON COMPANY, INC.Inventors: Jérôme Lebas, Stanislas Le Tallec, Antoine Provost, Stéphane Le Merdy, Phebe Helena Preethi, Paul Anthony Way
