Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
