Abstract: A first casing has an internal cylindrical region defined as a floating/sinking guiding region for a float valve. The wall that forms the cylindrical region includes ventilation windows. A second casing surrounds the first casing to form, about the periphery of the first casing, a ventilation passage that guides fuel vapor in a fuel tank to the ventilation windows through a region that surrounds the first casing. In addition, the second casing surrounds the first casing from a first connection hole side to form, about the periphery of the first casing, a first ventilation passage that guides the fuel vapor in the fuel tank to the ventilation windows through the region that surrounds the first casing, and a second ventilation passage that has a larger passage cross-sectional area than the first ventilation passage. These ventilation passages stabilize floating/sinking operation of the float.

Abstract: When a fuel tank inclines, a valve body device for the fuel tank restricts the flow of fuel to the exterior of the fuel tank, thereby preventing environmental pollution and improving fuel consumption. A rise/fall member and a valve body are lowered by an urge force less than a combined weight of the valve body and the rise/fall member, thereby creating an opening in a valve portion. A coil spring expands and the valve body contacts convex portions on a first inner surface of a cylinder main body. After a pressure reduction at a communication port of a resistance member, the fuel flows from a small-diameter space of a blow-up member, so that the flowing fuel pushes up the valve body and the rise/fall member closes the valve portion together with the urge force of the coil spring.

Abstract: A filler cap for a fuel tank is disclosed and is configured to prevent environmental pollution and improve fuel consumption without discharging fuel or harmful gas to an exterior of the fuel tank. A rise/fall member and a valve body are lowered by an urge force that is less than a total weight of the valve body and the rise/fall member, thereby opening a valve portion. When the fuel tank inclines, a coil spring expands and the valve body contacts with convex portions on an inner surface of a cylinder main body. After a pressure reduces at a communication port of a resistance member, the fuel flows from a small diameter space of a blow-up member. The flowing fuel pushes up the valve body and the rise/fall member thereby closing the valve portion together with the urge force of the coil spring.

Abstract: A closure device provides an emergency degassing function, pressure equalization and condensate removal for a housing sealed off from the environment. The closure device has a frame, fastenable to a housing opening and having a frame opening, as well as a closure element, for closing the housing opening. The closure element is configured or arranged relative to the frame such that a path is formed in or through the closure element in a first closure position by the gravitational force acting on the closure element. The path enables an exchange of air between the housing interior and the environment as well as a discharge of condensation water. A second closure position, in which the path is sealed closed is producable by water impinging on the closure element from the environment. If a specified overpressure is exceeded, the closure element is detachable from the frame opening.

Abstract: An air control regulator regulates the amount of air flowing into the inlet of a combustion chamber by causing flowing air to support a disc located in the air passage against the force of gravity. Air passes around the edges of the disc and is channeled into a plurality of airflows by ovoid depressions in the inner surfaces of the regulator forming a venturi chamber. By regulating the airflow into the combustion chamber, combustion efficiency is improved.

Abstract: A fuel tank cap provides a safety valve mounted on a tubular vent stem for venting fluids from a fuel tank. The safety valve is adapted for engagement with the tubular vent stem so that the fluids may enter the safety valve. A pair of upper cavities communicate with the vent stem through small channels offset therefrom. The upper cavities contain valve balls seated by gravity against valve seats for restricting fluid flow from the vent stem into the upper cavities. One upper cavity provides a biasing spring seating its valve ball against the its valve seat. The upper cavities provide restrictors positioned for limiting movement of the valve balls away from their valve seats, and a cover sealingly engaged with the safety valve to form a small chamber. The upper valve body further provides exit channels for conducting the fluids to exit.

The closure/retainer has a plurality of locking fingers disposed thereabout, with the number, width and spacing of the fingers such that each window is engaged by at least one locking finger for any random rotary orientation of the closure/retainer. The closure/retainer is particularly suitable for automated axial assembly as for example in a fuel tank vapor vent valve for retaining the float in the tubular valve body.

Abstract: Filler neck for a fuel tank of a motor vehicle Filler necks have, as well as the filler pipe, additional lines for venting, valves and compensating reservoirs. Due to the multiplicity of individual parts and connections, filler necks involve a high outlay in terms of assembly and, because of the connections, have high fuel permeation. The new filler neck is to be easily mountable and have low permeation values.
