Abstract
The locking fuel nozzle is used to prevent spilling of fuel while filling two-inch fill tubes on railroad cars. The nozzle includes a nozzle tube that is secured to a pressurized fuel source. The nozzle tube is inserted into the opening of the fill tube and delivers fuel from the pressurized fuel source to a fuel receptacle. A sealing member is disposed along the nozzle tube. A compression member is slidably disposed along the nozzle for impacting the sealing member. A handle is secured to the compression member for forcing the compression member along the nozzle tube. The compression member compresses the sealing member forcing it to swell. The sealing member swells until it completely seals the opening of the fill tube and the compression member is then locked into place by the handle.
Claims18
A locking fuel nozzle, comprising:
- an elongate, generally cylindrical nozzle tube having a first end secured to a pressurized fuel source, a second end adapted to be inserted into a fill tube of a fuel receptacle, and an opening at said second end for delivering fuel from the fuel source to the fuel receptacle;
- a compressible sealing member disposed along said nozzle tube adjacent the opening at the second end of said nozzle tube;
- a compression member slidably disposed along said nozzle tube for impacting and compressing said sealing member;
- and
- a handle pivotally mounted to said fuel source for causing said compression member to impact said sealing member;
- whereby said sealing member creates a seal between the fill tube and said nozzle tube inserted therein to prevent fuel from spilling while delivering fuel to the fuel receptacle.
