Abstract: A hydrogen generation cartridge (12) for supplying hydrogen gas to the anode side of a fuel cell system. The cartridge (12) comprises a first compartment (30) containing a first reactant (32) and a second compartment (34) containing a second reactant (36). The first compartment (30) is positioned within the second compartment (34) and, prior to cartridge activation, the compartments (30,34) chemically isolate the reactants (32/36) from each other. To activate the cartridge (12), the first compartment (30) is opened (e.g., broken) to form a common chamber (40) with the second compartment (34), and the reactants (32/36) combine and react to generate hydrogen gas within this chamber 40.

Abstract: A T-handle for a filter includes an integral mechanical indicator. The T-handle indicator has a threaded portion that extends through a hole in the filter cover and retains the cover to a canister. The indicator includes a spring-biased button that provides a visual indication of whether the element needs to be replaced. The button is received in a body that is open to the pressure on the downstream side of the filter element. A pair of clips on the button engage the indicator body to retain the button in the inward (element change) position. The clips can be accessed when the T-handle indicator is removed from the filter to return the button to the outward (fresh element) position. The indicator button includes an axially-elongated slot extending radially through the button, and the body includes a corresponding pair of holes on opposite sides of the slot. A handle rod for rotating the T-handle projects through the holes in the body, and the button is constrained by the rod as the button slides within the body.

Abstract: A fuel filter includes a pair of housing portions defining an interior cavity. A filter element is provided in surrounding relation to a fuel pump. A diverter plate assembly supported in the housing in sealing relation with one of the housing portions, the pump and the filter element, includes a bypass valve with a ball member. The bypass valve is normally closed when the pump is operational, and fuel flow passes from the inlet, through the filter element, and through the pump to the outlet. When the pump is not operational, the bypass valve opens, and fuel flow passes from the inlet through the filter element, and then directly to the outlet, bypassing the fuel pump. The diverter plate assembly includes a segmented collar that couples the assembly to one of the housing portions; a lip seal sealing to the pump; an outer rim that seals to one of the housing portions; and an annular flange that seals to the filter element.

Abstract: A recirculating valve for the fuel system of an internal combustion engine includes a valve body with a fuel supply passage and a fuel return passage. An air separation chamber and a restricted orifice are provided in the fuel return passage. A pressure valve allows excess heated return fuel in the air separation chamber to recirculate with the fuel in the fuel supply passage. The valve also directs return air back to the tank and prevents the air from passing to the engine. A thermal actuator maintains the pressure valve in a closed condition when the fuel increases above a predetermined temperature. A relief valve can be provided in the fuel return outlet port to allow fuel to easily pass back to tank during normal operating conditions.
