Patent number: 9089799Abstract: A fluid distribution system may include a by-pass fluid filter that combines high volume, in-tank fluid filtration with low volume fluid delivery to an external device such as an SCR injector. One or more outlet ports located along the fluid filter housing can be configured to discharge fluid toward other fluid distribution system components. In systems such as SCR systems, where the liquid reducing agent may freeze when not in use, directing already thawed liquid toward other system components can help thaw the frozen reducing agent at desired locations first. The fluid distribution system can also be arranged so that flow through the filter is in the same direction during the distribution cycle and during the purge cycle.Type: GrantFiled: July 30, 2012Date of Patent: July 28, 2015Assignee: TI Group Automotive Systems, L.L.C.Inventor: Lynwood F.
