Abstract: A refueling nozzle 100 comprising a housing 102 which is of a “dry breaks” construction. The rear end of the nozzle housing 102 includes a rear chamber 104 in which a piston 106 is housed for axial reciprocation. The refueling nozzle 100 is provided with a spring 118 which operatively cooperates with the piston head 106 so as to urge the valve into the “on” position wherein the refueling nozzle 100 is open. An end cap 109 is fitted to the rear end of the nozzle housing 102 wherein the rear chamber is enclosed. The end cap 109 includes a plurality of spaced apart and coaxial annular grooves such as 122 each being adapted to removably receive a locking element in the form of a C-clip 124 which bears against the flange of a spring retaining element 120 so as to compress the spring 118 against the piston head 106 at the required force. Thus, a user can adjust the biasing force in the spring 118.

Abstract: The present invention relates generally to a refuelling nozzle 100 comprising a housing 102 which is of a “dry breaks” construction. The rear end of the nozzle housing 102 includes a rear chamber 104 in which a piston 106 is housed for axial reciprocation. The refuelling nozzle 100 is provided with a spring 118 which operatively cooperates with the piston head 106 so as to urge the valve into the “on” position wherein the refuelling nozzle 100 is open. An end cap 109 is fitted to the rear end of the nozzle housing 102 wherein the rear chamber is enclosed. The spring 118 is generally elongate and at one end bears against the piston head 106 whilst an opposite end is retained by a spring retaining element 120. The end cap 109 includes a plurality of spaced apart and coaxial annular grooves such as 122 each being adapted to removably receive a locking element in the form of a C-clip 124 which bears against the flange of the spring.
