Patent number: 6213331Abstract: A one quarter turn fuel cap assembly is provided with a fuel cap and a sleeve. The assembly is closed by rotation of the cap through a one quarter turn. Following rotation, a cam permits a spring disposed in the fuel cap to expand and engage a seal against a rim of the sleeve to close the assembly without rotating the seal relative to the ring.Type: GrantFiled: February 9, 1998Date of Patent: April 10, 2001Assignee: Shaw Aero Development, Inc.Inventors: Thomas G. Morgan, David Charles Juleff

Patent number: 5845800Abstract: A filler cap assembly includes a sleeve welded to a tank wall, and a non-indexing filler cap. The cap is formed with top and bottom members, each member having an outwardly bevelled surface opposing a corresponding surface on the other member. An elastic O-ring is positioned between the two surfaces. The top member and base member are held together by an axially extending shaft, with a spring biasing apart the two members. The shaft is connected in a hinged manner to a cam lever. Activation of the cam lever brings the two opposing surfaces together, forcing the O-ring outward to form a seal with the sleeve. The filler cap and the sleeve's inner wall are provided with additional features which maintain the filler cap in the sleeve.Type: GrantFiled: February 14, 1997Date of Patent: December 8, 1998Assignee: Shaw Aero Development, Inc.Inventors: James Shaw, Thomas George Morgan, Charles Gordon Grandy

Patent number: 5211194Abstract: A manually operated fuel control valve having at least two operating positions, one being an "on" position for feeding fuel through a main fuel inlet when the fuel tank is full and the other a "reserve" position for feeding fuel through a reserve fuel inlet when the fuel tank is nearly depleted. The valve includes a valve closure means which is disposed in a partial sealing relation with the reserve inlet when fuel is being fed through the main inlet. The fuel valve also includes a shear zone to cause the valve to break away from the fuel tank in the event of an accident. The internal parts of the valve are biased toward a valve closing position to immediately shift and completely close the valve against further flow of fuel upon breaking of the valve.Type: GrantFiled: July 31, 1992Date of Patent: May 18, 1993Assignee: Shaw Aero Development, Inc.Inventors: Richard E. Scott, Thomas G. Morgan, James Cline

Patent number: 4993246Abstract: An expansion plug including a cam lever with a securing portion, and a top plate with a flange. A first hole is centered in the securing portion and a second hole is centered in the flange. During engagement of the cam lever, the securing portion adjoins the flange, aligning the two holes. Thus, a lock may be inserted through both holes to securely fasten the cam lever to the top plate.Type: GrantFiled: March 8, 1990Date of Patent: February 19, 1991Assignee: Shaw Aero Development, Inc.Inventor: Jan Kopper

Patent number: 4892216Abstract: An improved fuel filler cap for fuel tanks of motor vehicles is disclosed. A cap body member is attached by an actuator rod to an anchor disc, which mates with a tank adapter. When an actuator handle is rotated from a free to a locked position, the anchor disc is engaged with the adapter and drawn towards the underside of the cap, thus insuring a good seal between the cap and the adapter. A first spring disposed between the actuator rod and anchor disc limits the pressure in the tank, such that if an overpressure occurs, the cap is permitted to lift entirely off the adapter, quickly relieving the overpressure. A second spring is preferably provided to positively urge the anchor disc away from the cap upon release of the handle, providing superior operating feel and over-center 10 locking of the handle. The outer surface of the cap is configured so that impacts are absorbed by the adapter, preventing leakage of the cap.Type: GrantFiled: January 13, 1989Date of Patent: January 9, 1990Assignee: Shaw Aero Development Inc.Inventor: Richard E.
