Patent number: 10604087Abstract: According to an aspect, the present embodiments may be associated with a heat shield including a sealing member. In an embodiment, the sealing member is positioned along at least a portion of a partially hemmed edge and retained thereby. Thus, the heat shield is capable of providing insulative and/or sealing properties when used, specifically thermal, vibrational and/or acoustical shielding, as well as limiting fluid flow across the edge of the heat shield.Type: GrantFiled: June 1, 2016Date of Patent: March 31, 2020Assignee: LYDALL, INC.Inventors: Gregory M. Slimko, Julien Forgeard, Paul Schlappa, John M Lowry

Patent number: 10077702Abstract: An exhaust gas treatment system for reducing emissions from an engine includes an exhaust conduit adapted to supply an exhaust stream from the engine to an exhaust treatment device. The conduit includes an aperture. An injector injects a reagent through the aperture and into the exhaust stream. A flow modifier is positioned within the exhaust conduit upstream of the injector. The flow modifier increases the velocity of the exhaust gas at a predetermined location within the conduit relative to the injected reagent.Type: GrantFiled: May 6, 2016Date of Patent: September 18, 2018Assignee: Tenneco Automotive Operating Company Inc.Inventors: Ryan A. Floyd, John M. Lowry, Larry J. Geer

Patent number: 8998116Abstract: An injector for injecting a reagent includes an electromagnet and an axially translatable valve member positioned within a housing. The valve member is moveable from a seated position to an unseated position in response to energizing the electromagnet. The valve member includes a hollow tube including a curled end having a reduced diameter sized to allow a ball to partially extend beyond the tube end but not pass through the tube. The tube includes an inwardly extending detent restricting the ball from movement within the tube. A pintle head is fixed to the tube and positioned proximate the electromagnet.Type: GrantFiled: September 7, 2012Date of Patent: April 7, 2015Assignee: Tenneco Automotive Operating Company Inc.Inventors: John M. Lowry, David Blumhardt, Eric Grant

Patent number: 8402750Abstract: A reagent injection system for reducing emissions from an engine includes a reagent container. A heating element is positioned in a heat transfer relationship with reagent stored within the container. An interchange tube includes a first end in receipt of a recirculated liquid reagent and a second open end positioned in the container. The interchange tube includes a bleed-off tube branching off of the interchange tube between the first and second ends. A terminal end of the bleed-off tube is positioned within a vapor dome above a surface of the reagent.Type: GrantFiled: October 17, 2011Date of Patent: March 26, 2013Assignee: Tenneco Automotive Operating Company Inc.Inventors: Ryan A. Floyd, Eric Grant, Dan McAninch, David Blumhardt, John M. Lowry, Michael L. Shovels
