摘要： A fuel dispensing nozzle and a method utilizing that dispensing nozzle, are provided, the method comprising the steps of: providing a sealing means effective to mate in a sealing relationship with a fuel tank inlet, the sealing means comprising a boot having an elastomeric sealing surface, a source of pressurized gas, a channel providing communication from the source of pressurized gas to outside of the boot wherein pressure on the elastomeric sealing surface restricts flow through the channel, and a means to block fuel flow through the fuel dispensing nozzle when a threshold pressure or greater exists at the source of gas supply, the threshold pressure indicative of a sealing relationship between the sealing surface of the boot and a fuel tank inlet; mating the sealing surface to the fuel tank inlet; and passing fuel into the fuel tank only when the pressure within the gas supply conduit exceeds the threshold pressure.

摘要： A refuelling system is provided, the system comprising: a seal cylinder defining the outside surface of an axial vapor recovery volume within the seal cylinder having a first end and a second end; a first flexible conduit to supply fuel to within the seal cylinder through the first end; a movable seal piston within the seal cylinder connected to the first flexible conduit, the seal piston effective to isolate a vapor recovery volume within the seal cylinder from the atmosphere surrounding the flexible fuel conduit; a fuel insert tube connected to the seal piston and extending through at least a portion of the vapor recovery volume; a boot seal attached to the seal cylinder at the second end of the axial vapor recovery volume, the boot seal effective to seal with a fuel tank inlet nozzle; and a device to move the seal piston laterally through the seal cylinder and thereby extending the second flexible conduit through the second end of the axial vapor recovery volume and into a fuel tank inlet nozzle when the boot seal is mated to the fuel tank inlet nozzle.
