  • Patent number: 8905092
    Abstract: A pressure brace device holds a gas pump handle in the open position, can store small items such as a SPEEDPASS, and can be clipped to small-gauge items such as a key ring. The pressure brace comprises a depressible plunger within a spring-loaded housing. The plunger is compressed into the housing while the brace is situated in the gas pump handle, then released. The outward pressure provided by the spring holds the handle in the open position, allowing gas to flow through the pump.

  • Patent number: 8646495
    Abstract: A fuel tank for vehicles has a filler tube and a filling level limiting device, with the filler tube comprising, in the interior of the fuel tank, a closing device which interacts with an actuating device which is composed of: a) a frame which is fastened in the interior of the fuel tank and which has a force store which actuates the closing device; b) a locking arrangement which holds the force store in the stressed state; c) a release mechanism which is operatively connected to a float; and d) a stressing mechanism for stressing the force store. The actuating device ensures that a flap closes precisely when a nominal filling level is reached, and does not open again even under intense fluctuation of the liquid level.

  • Patent number: 4559982
    Abstract: A pressure actuated poppet valve for a fuel dispensing nozzle is disclosed having a piston therein movable between a first and a second position. In the first position, the piston holds a plurality of coupling or latching balls in coupling engagement with an axially movable stem so that upon a user pulling the actuator handle or lever of the dispensing nozzle, the poppet valve is opened for the dispensing of fuel. When the dispenser goes off such that there is no fuel pressure in the hose upstream from the nozzle, a spring within the poppet valve pushes the piston from its first to its second position, thus permitting the coupling balls to move clear of the stem, allowing the poppet valve to close, and preventing opening of the poppet valve upon the subsequent actuating of the nozzle handle.
