Abstract: A diesel dosing module utilizes a diesel fuel shut-off valve, a diesel fuel dosing valve to provide dosing fuel to the inlet of a diesel oxidation catalyst and an air purge valve to purge fuel from a dosing line attached to the diesel dosing module and from a nozzle attached to a distal end of the dosing line. The valves are attached to a housing manifold which is remotely positionable from the nozzle and the high heat areas of the vehicle.

Abstract: A valve assembly (10) comprises a valve body (20), a first valve (22a), a second valve (22b), and a manual override device (24). The valve body (20) defines a first inlet (30a), a second inlet (30b), and an outlet (32). Each valve (22a/22b) includes a plunger (68a/68b) that is electrically movable between a position whereat the corresponding inlet (30a/30b) communicates with the outlet (32) and a position whereat the inlet (30a/30b) is sealed from the outlet (32). The override device (24) is manually movable to override positions whereat the electrical control of one of the valves (22a/22b) is overridden and the plunger's seat-sealing surface (72a/72b) is caused to move so that the corresponding inlet (30a/30b) communicates with the outlet (32).

Abstract: A filter module for filtering a flow of fluid employs a base member which either mounts a blanking plug or a diverter valve module. The plug is replaced by a diverter valve module for use with those engines that require an auxiliary source of low pressure fuel. A solenoid valve is housed in the module. A pressure regulator valve positioned in the valve module maintains a backpressure in the filter assembly to insure that there is sufficient head to drive the flow of fuel to the engine.

Abstract: A filter assembly employs a bracket and a base which mounts a disposable filter element cartridge. The bracket has a bracket mounting portion for mounting the bracket to a vehicle and a base mounting portion for mounting the base. The bracket mounting portion may be offset from the base mounting portion to provide mounting flexibility. The base mounting portion has a plurality of outwardly projecting catches that engage and support a corresponding number of hangers on the base. A threaded stud mounted on the bracket is received between the hangers. A nut in threaded engagement with the stud is torqued into engagement with the base, securing the base to the bracket.

Abstract: A fuel filter assembly employs a spring-loaded collar which retains the disposable cartridge to the base. The collar carries a wave spring and comprises followers which ascend a spiral ramp of the base for securing the disposable cartridge to the base in a positive locked position. The filter assembly also incorporates an efficient bleed orifice and a pair of axial spaced seal rings for implementing a fluid seal with the received disposable cartridge.
