  • Patent number: 10994605
    Abstract: Methods and systems are provided for reducing an amount of fuel vapors that are routed to a fuel vapor storage canister during a refueling event, in response to an indication that a fuel dispenser that is dispensing fuel to a fuel tank is underperforming. In one example, a method comprises increasing a pressure in the fuel tank responsive to an indication that the fuel dispenser is dispensing fuel at a first rate that is at least a threshold amount below a second rate, without changing the first rate at which the fuel dispenser is dispensing the fuel. In this way, fuel vapor recirculation may be improved and an amount of fuel vapors routed to the canister reduced, which may thus reduce opportunities for release of undesired evaporative emissions to atmosphere.

  • Patent number: 10955065
    Abstract: A locking apparatus for a rotatable lever of the type used to control a valve. The apparatus is formed from a wedge-like base element, a wedge-like blocking element and a plurality of guide posts. The base element is fixedly attached to the valve body. The blocking element is penetrated by plural guide passages. Each guide post passes through a corresponding guide passage in the blocking element, and is threaded into the base element. A spring is interposed between the blocking element and the base element. When the spring is uncompressed, the blocking element obstructs rotation of the lever. External pressure in opposition to the spring can urge the blocking element toward the base element. When the blocking element is so positioned, the lever may be rotated.

  • Patent number: 10940964
    Abstract: The invention discloses a device for filling an electric cigarette, more specifically for filling a consumable-material tank of an electric cigarette wherein the device has a first tank for accommodating a consumable material and a second tank for accommodating air, wherein the device is designed such that the volumes of the tanks can be altered inversely by means of an actuating device, and therefore a pressing action and an intake action can be established at connections of the tanks. By virtue of the device being connected to a consumable-material tank of an electric cigarette, it is thus possible, while the consumable-material tank is being filled with consumable material, for the air displaced by the consumable material to be simultaneously extracted from the electric cigarette.
