Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
213 words
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.
Claim 2
Dependent Claim
213 words
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.
Claim 3
Dependent Claim
24 words
The refuelling system of claim 1 further comprising an arm interconnected with the seal cylinder for removal of a standard automotive fuel tank cap.
Claim 4
Dependent Claim
26 words
The refuelling system of claim 1 further comprising an arm interconnected with the seal cylinder for opening of a hinged lid covering the fuel tank cap.
Claim 5
Dependent Claim
40 words
The refuelling system of claim 3 wherein the arm provided for opening of a hinged lid covering the fuel tank cap being arranged to open and hold the hinged lid in an open position while a vehicle is being refuelled.
Claim 6
Dependent Claim
32 words
The refuelling system of claim 1 wherein the means to move the seal piston laterally comprises a friction roller that moves the flexible fuel conduit laterally from outside of the seal cylinder.
Claim 7
Dependent Claim
25 words
The refuelling system of claim 1 wherein the seal cylinder comprises a refuelling tube sleeve slidably connected to a fixed portion of the seal cylinder.
Claim 8
Dependent Claim
51 words
The refuelling system of claim 6 wherein the refuelling tube sleeve is connected to the seal piston by a coiled spring so that movement of the piston laterally toward the second end of the seal cylinder also urges the refuelling tube sleeve out of the fixed portion of the seal cylinder.
Claim 9
Dependent Claim
26 words
The refuelling system of claim 1 further comprising a means to remove vapors from the vapor recovery volume for removal of hydrocarbons from the removed vapors.
Claim 10
Dependent Claim
42 words
The refuelling system of claim 6 further comprising a seal block attached to the fixed portion of the seal cylinder, the seal block effective to provide a vapor seal between the refuelling tube sleeve and the fixed portion of the seal cylinder.
Claim 11
Dependent Claim
34 words
The refuelling system of claim 1 wherein the means to move the seal piston laterally comprises a rodless cylinder having a connection to the seal piston through a sealed slot in the seal cylinder.
Claim 12
Dependent Claim
38 words
The refuelling system of claim 2 wherein the arm for removal of a standard automotive fuel tank cap comprises a rotating grabbing head, the rotating grabbing head effective to be secured to a standard automotive fuel tank cap.
Claim 13
Dependent Claim
35 words
The refuelling system of claim 11 wherein the grabbing head comprising two inflatable boots that inflate and expand to apply grabbing pressure to sides of a raised ridge on the standard automotive fuel tank cap.
Claim 14
Dependent Claim
33 words
The refuelling system of claim 12 further comprising a means to prevent inflation of the inflatable boots when the raised ridge is not in a position to be grabbed by the inflatable boots.
Claim 15
Dependent Claim
44 words
The refuelling system of claim 11 wherein the grabbing head comprises a piston capable of extending perpendicular to the axis of rotation of the grabbing head and pinching a raised ridge of the fuel tank cap against a protruding lip of the grabbing head.
