Patent number: 11614010Abstract: A panel assembly includes a panel member, a frame member, and at least one first bar member, and at least one second bar member. The at least one first bar member and the at least one second bar member divide the panel member into a plurality of first areas defining a first height and a first width. The panel assembly also includes a plurality of support arrangements for dividing each first area into a plurality of second areas. Each support arrangement includes a first support member defining a first length such that the first width defined by the first area is greater than the first length. Each support arrangement also includes a second support member defining a second length such that the first height defined by the first area is greater than the second length.Type: GrantFiled: September 1, 2020Date of Patent: March 28, 2023Assignee: Caterpillar Inc.Inventors: Samuel S. Kumar, Courtney E. Strauser, Scott M. Peters, Theron J. Cassidy

Patent number: 10328366Abstract: An inlet filter is disclosed for use with a reductant tank having a fill spout. The inlet filter may have a generally cylindrical base portion with an open top end and an open bottom end and configured for mounting inside the fill spout. The inlet filter may also have a mesh bag with a top connected to the generally cylindrical base portion, a folded bottom, and open side edges. The inlet filter may further have a bag carrier configured to close the open side edges.Type: GrantFiled: January 22, 2016Date of Patent: June 25, 2019Assignee: Caterpillar Inc.Inventors: Jason W. Hudgens, Theron J. Cassidy, Dave T. Ahlman, Shawn R. Herold

Publication number: 20170189837Abstract: A fluid reservoir for accommodating a fluid reductant used in an SCR exhaust treatment process may include various styles or designs of bag filters to filter debris and contaminants from the reductant prior to being channeled out of the reservoir. To secure the bag filter to a header assembly accommodating the various inlet and outlet tubes, in one aspect, the bag filter is adapted to fit around a header boss descending from the header assembly and protruding into the reservoir volume. Various configurations for the bag filter can be utilized to secure the bag filter to the header boss in a manner that isolates the tubes of the header assembly from the remainder of the reservoir volume to prevent debris and the like from being unintentionally drawn out of the reservoir.Type: ApplicationFiled: January 6, 2016Publication date: July 6, 2017Applicant: Caterpillar Inc.Inventors: Shawn Herold, Matthew F. Fahrenkrug, Jason W. Hudgens, Theron J. Cassidy

Publication number: 20170122170Abstract: A fluid reservoir for accommodating a fluid reductant used in an SCR exhaust treatment process may include various styles or designs of bag filters to filter debris and contaminants from the reductant prior to being channeled out of the reservoir. To secure the bag filter to a header assembly accommodating the various inlet and outlet tubes, in one aspect, the header assembly may be associated with a base assembly designed to reduce leak paths allowing reductant to bypass the bag filter. In another aspect, the bag filter may be secured directly to the header assembly without the base assembly.Type: ApplicationFiled: October 30, 2015Publication date: May 4, 2017Applicant: CATERPILLAR INC.Inventors: Matthew F. Fahrenkrug, Jason W. Hudgens, Theron J. Cassidy, Shawn Herold

Patent number: 9468875Abstract: A fluid reservoir includes a reservoir body forming a reservoir volume and a header opening. A header seals the header opening and includes at least a heater disposed within the reservoir volume and a fluid draw conduit. A bag filter is connected to the header such that it completely encloses the heater and the fluid draw conduit such that, when fluid is drawn from the reservoir volume through the sump location, the fluid is filtered by the bag filter.Type: GrantFiled: January 14, 2014Date of Patent: October 18, 2016Assignee: Caterpillar Inc.Inventors: Theron J. Cassidy, Jason W. Hudgens, David Ahlman

Patent number: 9248390Abstract: A fluid delivery system includes a fluid reservoir having an inlet screen and a main reservoir filter. The fluid reservoir is adapted to enclose a fluid therewithin and includes a reservoir body forming a reservoir volume that is fluidly connected to an inlet conduit, a supply conduit, and a return conduit. The inlet screen is disposed fluidly along the inlet conduit and adapted to filter a fluid provided to fill the reservoir through the inlet conduit. The main reservoir filter is disposed fluidly along the supply conduit and adapted to filter a fluid drawn from the reservoir volume and provided through the supply conduit to a pump.Type: GrantFiled: February 3, 2014Date of Patent: February 2, 2016Assignee: Caterpillar Inc.Inventors: Jason W. Hudgens, Theron J. Cassidy, Jeffrey R. Ries, Lynsey Hart

Publication number: 20150361847Abstract: A valve assembly for an aftertreatment system is disclosed. The valve assembly includes a coolant conduit. The coolant conduit is configured to allow a coolant flow therethrough. The valve assembly also includes a valve element having a valve passage. The valve element is configured to control a reductant flow through the valve passage. The valve assembly further includes a coupling mechanism provided on the valve element. The coupling mechanism is configured to attach the valve element to the coolant conduit such that a temperature of the valve assembly is controlled based on the coolant flow.Type: ApplicationFiled: June 13, 2014Publication date: December 17, 2015Inventors: Matthew F. Fahrenkrug, Theron J. Cassidy, Jason W. Hudgens, Jinhui Sun
