Publication number: 20060231138Abstract: A vent apparatus is opened to allow free flow of fuel vapor from a vehicle fuel tank through the vent apparatus to a fuel vapor recovery canister during tank refueling until a predetermined level of liquid fuel is reached in the vent apparatus. Once refueling has been completed, the vent apparatus is closed to block or limit further flow of liquid fuel to the vent apparatus. At the same time, fuel vapor discharge passageways in the vent apparatus that had been closed once the fuel tank had been filled to a predetermined capacity with liquid fuel are reopened so that fuel vapor can flow freely from the fuel tank to the canister even though the volume or height of liquid fuel in the fuel tank has not decreased since the tank was filled during refueling.Type: ApplicationFiled: March 28, 2006Publication date: October 19, 2006Applicant: Stant Manufacturing Inc.Inventor: Jeffrey Devall

Patent number: 6840274Abstract: A vent apparatus (10) includes a tank mount (12) made of a weldable plastics material and a fuel system component such as a valve assembly (13). Valve a assembly (13) includes a valve housing (14) made of a nonweldable plastics material and a valve (21) movable in a valve chamber (24) formed in valve housing (14) to open and close an aperture (23) leading to a venting outlet (22). Tank mount (12) supports valve housing (14) in a position in a mounting aperture (16) formed in a fuel tank (18). Valve housing (14) is made by injecting on-weldable plastics material into a mold containing the pre-molded tank mount (12).Type: GrantFiled: June 1, 2000Date of Patent: January 11, 2005Assignee: Stant Manufacturing Inc.Inventors: Nancy Williamson, Thomas Blease, Jeffrey Devall, Dwight Smith

Patent number: 6561211Abstract: A vent valve for use with a fuel containing system including a fuel tank and a vapor recovery system. The vent valve includes a housing which communicates with the fuel tank and the vapor recovery system. The housing defines a path between the fuel tank and vapor recovery system. A float valve is positioned in the housing and is responsive to the presence of fuel in the tank. The housing has at least one vacuum vent positioned in the path. An umbrella valve is carried on the housing and positioned between the fuel tank and the vapor recovery system. The umbrella valve has a wall defining an orifice extending therethrough and a cover portion extending from the wall. The orifice is selectively sealed at one end by the float valve and is selectively sealed at the opposite end by the head valve.Type: GrantFiled: October 18, 2001Date of Patent: May 13, 2003Assignee: Stant Manufacturing Inc.Inventor: Jeffrey Devall

Patent number: 6422261Abstract: A fuel system apparatus for installation on a fuel tank. The apparatus includes a first portion extending at least partially interiorly of the fuel tank and the apparatus is installed on the fuel tank. A second portion is positioned at least partially extending into the fuel tank when the apparatus is installed on the fuel tank. A mount is provided which is at least partially retained between the first portion and the second portion. The mount at least partially extends from between the first portion and the second portion. The mount in size and dimension or at least substantially corresponding to an opening in the fuel tank to which the apparatus is attached. The mount is attachable to the fuel tank and prevents permeation of hydrocarbon vapor therethrough.Type: GrantFiled: February 5, 2001Date of Patent: July 23, 2002Assignee: Stant Manufacturing Inc.Inventors: Dennis DeCapua, Jeffrey Devall, Gregory Brown

Patent number: 6003499Abstract: An apparatus is provided for controlling venting of vapor to and from a fuel tank. The apparatus includes a housing and first and second valves positioned in the housing. The first valve controls the primary flow of vapors from the fuel tank and includes an aperture permitting an auxiliary flow of vapor to and from the fuel tank. The second valve controls the auxiliary flow of vapor to the fuel tank and includes first and second apertures permitting vapor to flow to the fuel tank. The second valve moves between a first position permitting vapor to flow through the first aperture and a second position permitting vapor to flow through the first and second apertures at a greater flow rate.Type: GrantFiled: January 7, 1999Date of Patent: December 21, 1999Assignee: Stant Manufacturing Inc.Inventors: Jeffrey Devall, Jon Farmer, Nancy Amburgey
