Patent number: 10814262Abstract: A flow control device for controlling fluid flow into a filter cartridge. The flow control device comprises a hollow body comprising a fluid flow inlet and a fluid flow outlet. The flow control device is configured to split fluid flowing toward the filter cartridge into at least two distinct flow streams, a first distinct flow stream of the at least two distinct flow streams being a flow stream which flows into the hollow body through the fluid flow inlet and out of the hollow body through the fluid flow outlet, and a second distinct flow stream of the at least two distinct flow streams being a flow stream which does not flow into the hollow body through the fluid flow inlet and out of the hollow body through the fluid flow outlet.Type: GrantFiled: February 24, 2016Date of Patent: October 27, 2020Assignee: AAF LTD.Inventors: Paul Jackson, Mark Smith, Rodrigo Nessi
