Automated refueling system
First Claim
1. A refuelling 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 flexible fuel conduit to supply fuel to within the seal cylinder through the first end;
a movable piston within the seal cylinder connected to the flexible fuel conduit, the piston effective to isolate at least a portion of the axial vapor recovery volume within the seal cylinder from the atmosphere surrounding the flexible fuel conduit;
an insert tube connected to the seal piston and extending through at least a portion of the vapor recovery volume wherein a portion of the insert tube within the seal cylinder defines the inside surface of the axial vapor recovery volume;
a seal boot 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 means to move the piston laterally through the seal cylinder and thereby moving said flexible fuel conduit through the seal cylinder and extending the insert tube 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.

Abstract
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.
