Abstract:
A fill limit control valve assembly (10) adapted for disposition in a vehicle fuel tank (12), said valve assembly (10) comprising;a housing (14) having a valve portion (16) with an outlet connector (22) adapted for connection to a fuel tank (12) and a float portion (18) for extending into the fuel tank (12), said valve portion (16) defining a vent opening (28) for venting vapors from the fuel tank (12), a float (30) movably supported by said float portion (18) for movement between an open position spaced from said vent opening (28) and a closed position seating against and sealing said vent opening (28), and a liquid fuel trap disposed above said vent opening (28) to limit liquid fuel flow therethrough to said outlet connector (22), said liquid fuel trap including a baffle barrier (32) surrounding said vent opening (28), and a return cup (34) having a base (36) overlying said baffle barrier (32) with a dependent rim (38) surrounding said baffle barrier (32) for forcing the flow of said vapors from said vent opening (28) through a U-turn, and legs (48) extending downwardly from said rim (38) to support said liquid fuel trap in said valve portion (16), wherein said valve portion (16) includes a bottom (40) supporting said baffle barrier (32) and defining said vent opening (28) and an outer wall (42) extending from said bottom (40) and spaced from and surrounding said rim (38) for defining a collection reservoir below said rim (38), said baffle barrier includes drain holes (44) for draining liquid from said reservoir back through said vent opening (28), and said return cup (34) includes a bullet (46) extending from said base (36) thereof and into said baffle barrier (32) to define an annular passage for dividing said vapor flow from said vent opening (28).
