Patent number: 8931508Abstract: A vapor isolation valve includes a first chamber in fluid communication with a fuel tank and a second chamber disposed with respect to the first chamber. A diaphragm is disposed between the first and second chambers, has an orifice allowing fluid communication therebetween, and is moveable between a diaphragm open position and a diaphragm closed position. A third chamber is disposed adjacent the first chamber, relative to the diaphragm, and is in fluid communication with an exit passage. The diaphragm open position allows fluid communication between the first and third chambers, and the diaphragm closed position substantially restricts fluid communication therebetween. A pilot valve is disposed between the second and third chambers and is selectively moveable between a pilot open position configured to allow fluid communication between the second and third chambers and a pilot closed position configured to block fluid communication therebetween.Type: GrantFiled: August 17, 2009Date of Patent: January 13, 2015Assignee: Eaton CorporationInventors: Charles J.

Patent number: 7458391Abstract: A fuel filler tube assembly including a one-way valve or check valve. The tube assembly is adaptable for pre-assembly on either a metal or plastic fuel tank and employs a common check valve with an adapter tube for plastic tanks. The valve employs a flapper with spaced ribs for deflecting a siphon hose away from the valve seal; and, the ribs are spaced to maintain the flow stream of he fuel during refueling and facilitating opening of the flapper.Type: GrantFiled: October 28, 2004Date of Patent: December 2, 2008Assignee: Eaton CorporationInventors: Pk Haridass Krishnamoorthy, Charles J.

Patent number: 7107971Abstract: Isolation valves of the invention are advantageously mechanically actuated. Such valves and associated methods comprise a first port in fluid communication with a first component; a second port in fluid communication with a second component; a third port in fluid communication with a third component; a diaphragm disposed within the valve for closing a normally open internal pathway to occlude fluid communication between the first port and the second port in response to a pressure differential across the diaphragm; and a flow sensitive pressure device for controlling the pressure differential across the diaphragm. Fluid flows from the second component to the third component upon closing of the normally open internal pathway. In an exemplary embodiment, isolation valves and methods of the invention are adapted for use in fuel tank emission control systems.Type: GrantFiled: October 15, 2004Date of Patent: September 19, 2006Assignee: Eaton CorporationInventors: Kenneth M. Spink, Andrew W. McIntosh, Robert P. Benjey, Charles J. Martin

Patent number: 7007726Abstract: A closure assembly and method for a capless fuel tank filler tube employs a housing with a flange adapted for mounting on a bulkhead having a nozzle size-discriminating and positioning aperture provided on the upper end of the filler tube. A sliding element in the housing has a nozzle opening offset from and normally closing the bulkhead aperture. Upon insertion of a refueling nozzle, a cam surface on sliding element causes the element to move to a position aligning the opening with the bulkhead aperture permitting the nozzle to be further inserted through the bulkhead. A projection on the sliding element may extend through a slot in the bulkhead for performing an auxiliary function such as releasing a flapper door latch.Type: GrantFiled: April 18, 2005Date of Patent: March 7, 2006Assignee: Eaton CorporationInventors: Charles J. Martin, Carl F. Binder

Patent number: 6932100Abstract: A flapper valve for push-in snap-lock attachment to a spud to be welded to a fuel tank and attached to a flexible filler tube hose. The flapper has an annular flexible seal overmolded thereon, preferably of elastomeric material. The flapper has a pair of trunnions, one of which has an extension or spindle with a torsion spring received thereover with one end of the torsion spring slidably anchored to a post on the flapper to form a flapper subassembly. The opposite end of the torsion spring is deflected to fit in a slot or groove in the body when the trunnions are snapped into slots formed by deflectable fingers formed integrally on the exterior of the tubular valve body for pivoting the flapper. Deflector vanes are provided on the upstream side of the flapper to protect the seal from the end of a siphon hose.Type: GrantFiled: May 23, 2003Date of Patent: August 23, 2005Assignee: Eaton CorporationInventors: Charles J. Martin, Christopher W. Creager

Patent number: 6880598Abstract: A wheel valve assembly for adjusting the air pressure within a pneumatic tire is provided that includes a body that extends from a first end in communication with a pressure source to a second end in communication with the tire. A low pressure differential operable valve member is received within the body. The valve member is moveable between open and closed positions for respectively allowing and preventing air communication between the internal segment and the external segment of the body. The check valve of the present invention is virtually unaffected by the centrifugal force of a rotating tire to substantially prevent back flow of the tire air when the tire is rotating at a relatively high speed.Type: GrantFiled: September 6, 2002Date of Patent: April 19, 2005Assignee: Eaton CorporationInventors: Gregory A. Haunhorst, Todd J. Vogel, Charles J. Martin, Chris L. Schwab

Patent number: 6497243Abstract: Apparatus and method of assembling an interior fuel systems component suitable for immersion in liquid fuel in a tank to an exterior component of different material weldable to the fuel tank. The exterior component is preferably formed of HDPE having a hardness in the range of about RR-40 to RR-80 and has an array of projections extending therefrom. The interior component has a corresponding array of radially extending slots having barbed edges for push on connection to the projections. The slots permit sliding movement due to material swelling of the projection on the barbs without loosening of the connection. The internal component is preferably formed of material comprising a member of the group consisting of Polyamide, Polyketone and Polyphenylamide and having a hardness in the range of about R112, such that the barbs deform the lugs to maintain the connection.Type: GrantFiled: November 2, 2000Date of Patent: December 24, 2002Assignee: Eaton CorporationInventors: Charles J.

Patent number: 5304500Abstract: Each diode of an indium antimonide electro-optical detector array on a dielectric backing transparent to optical energy to be detected includes a junction that less than about a half micron from the diode surface on which the energy is initially incident. The optical energy is incident on a P-type doped region prior to being incident on a bulk N-type doped region. Both P-and N-type doped regions of adjacent diodes are spaced from each other. Metal electrically connects the P-type doped regions together without interfering substantially with the incident optical energy. A multiplexer integrated circuit substrate extends parallel to the backing and includes an array of elements for selective readout of the electric property of the diodes. The elements and diodes have approximately the same topographical arrangement so that corresponding ones of the elements and diodes are aligned. An array of indium columns or bumps connects the corresponding aligned elements and diodes.Type: GrantFiled: July 12, 1993Date of Patent: April 19, 1994Assignee: Cincinnati Electronics CorporationInventors: Harold A. Timlin, Charles J. Martin
