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.

Publication number: 20130000741Abstract: In at least some implementations, a fluid level sensor for sensing the level of a fluid within a tank includes a fluid tube through which fluid flows under pressure, a pressure pulse inducer, a fluid level responsive member and a pressure sensor. The pressure pulse inducer is disposed within the fluid tube so that at least some of the fluid flowing through the fluid tube engages the pressure pulse inducer. The fluid level responsive member is operably associated with the pressure pulse inducer to provide a force on the pressure pulse inducer that varies as a function of the fluid level in the tank. And the pressure sensor at senses the pressure of the fluid flowing through the tube, where the pressure pulse inducer induces changes in the pressure of the fluid as a function of the fluid level and the changes in pressure are sensed by the pressure sensor.Type: ApplicationFiled: June 20, 2012Publication date: January 3, 2013Applicant: TI Group Automotive Systems, L.L.C.Inventor: Lynwood F.

Publication number: 20130000743Abstract: A selective catalytic reduction system includes a fluid distribution system for supplying an exhaust gas reducing agent. The system includes a liquid storage tank and a fluid distribution module with a fluid pump that draws liquid reducing agent from the tank volume and provides the liquid at a module outlet port, while simultaneously discharging excess liquid from a circulation line outlet within the tank volume. The circulation line outlet can be located at a bottom portion of the tank volume near other distribution module components to promote liquid circulation around the module components during a fluid distribution period, to promote thawing of frozen reducing agent at and around the module components, and to ensure a continuous supply of liquid to the fluid pump. The distribution module is also capable of purging liquid from fluid lines located outside the storage tank and returning the purged liquid to the tank volume.Type: ApplicationFiled: June 20, 2012Publication date: January 3, 2013Applicant: TI GROUP AUTOMOTIVE SYSTEMS, L.L.C.Inventor: Lynwood F.

Publication number: 20080178849Abstract: A method of relieving hot soak pressure in a fuel rail of a fuel injected internal combustion engine includes pressurizing fuel with a fuel pump when the engine is operating, and conveying the pressurized fuel through a check valve that prevents backflow of fuel from the fuel rail toward the fuel pump. A bypass path is in fluid communication between a location downstream of the check valve and a location downstream of the fuel pump and upstream of the check valve. The bypass path is opened when the engine is not operating so as to relieve fuel pressure downstream of the check valve to a level below a system operating pressure. Apparatuses are provided for carrying out the method.Type: ApplicationFiled: January 11, 2008Publication date: July 31, 2008Applicant: TI Group Automotive Systems, LLCInventor: Lynwood F. Crary

Patent number: 7188610Abstract: A no-return loop fuel injection system supplies fuel from a fuel pump to an injector fuel rail, through a fuel line. A biased closed pressure control valve communicates with the fuel line and has a valve head preferably of a diaphragm type carrying a fuel side having first and second areas which are segregated and defined by a valve seat when the pressure control valve is closed. An opposite second side of the pressure control valve is exposed to a reference pressure and a closure biasing force. The pressure control valve opens when a hydraulic opening force induced by a fuel pressure exerted upon the first area, plus a fuel pressure exerted upon the second area, is greater than the net reference pressure and closure biasing forces. Preferably, the first area is smaller than the second area, thus manipulating the effects of the fuel pressures exerted upon the first and second areas with respect to opening the valve.Type: GrantFiled: September 22, 2004Date of Patent: March 13, 2007Assignee: TI Group Automotive Systems, L.L.C.Inventors: Lynwood F.

Patent number: 7069913Abstract: A fuel delivery system with at least one fuel tank and at least two fuel chambers has a fuel transfer assembly preferably integrated into an in-tank fuel pump module for controlling fuel levels between the at least two fuel chambers. The fuel transfer assembly has a transfer jet which receives pressurized fuel from a fuel pump of the module and at least two control valves for dictating the source of low pressure fuel flowing into the transfer jet and discharged therefrom preferably into a fuel reservoir of the module. Preferably, one control valve is located in each fuel chamber. The control valve opens upon a pre-established high fuel level and closes upon low fuel level. The fuel chamber containing the open control valve is generally the source of fuel for the fuel pump module.Type: GrantFiled: August 18, 2005Date of Patent: July 4, 2006Assignee: TI Group Automotive Systems, L.L.C.Inventor: Lynwood F.

Publication number: 20040226541Abstract: A no-return loop fuel injection system supplies fuel from a turbine-type fuel pump to an injector fuel rail, through a fuel pressure valve assembly capable of flowing supply fuel to the injector rail, and reverse flowing fuel from the rail and back through the pump to relieve rail fuel pressure. Preferably, the pressure valve assembly has a pressure control valve of a diaphragm type which is biased closed via a spring disposed within a reference chamber defined between a housing and a side of the diaphragm and vented to atmosphere. A fuel chamber defined between an opposite side of the diaphragm and a valve body communicates between a pump-side port and a rail-side port. With the valve in a closed position, the fuel chamber is divided into a rail sub-chamber and a pump sub-chamber via the sealing relationship between a valve seat and the diaphragm, held closed by a closure biasing force of the spring.Type: ApplicationFiled: January 28, 2004Publication date: November 18, 2004Inventors: Lynwood F.

Patent number: 6634341Abstract: A high flow rate fuel vapor vent and rollover valve assembly with a float valve that provides a progressive closing of a vapor outlet to control the venting of fuel vapors from a fuel tank and the addition of liquid fuel to the tank. The float closes a portion of the vapor outlet in response to liquid fuel at a first level in a vehicle fuel tank. A body completely closes the vapor outlet in response to rollover attitudes of the vehicle. One or more separate baffles are constructed and arranged to prevent the escape of liquid fuel through the vapor outlet.Type: GrantFiled: October 12, 2001Date of Patent: October 21, 2003Assignee: Walbro CorporationInventors: Lynwood F.
