Abstract: A fuel tank for vehicles has a filler tube and a filling level limiting device, with the filler tube comprising, in the interior of the fuel tank, a closing device which interacts with an actuating device which is composed of: a) a frame which is fastened in the interior of the fuel tank and which has a force store which actuates the closing device; b) a locking arrangement which holds the force store in the stressed state; c) a release mechanism which is operatively connected to a float; and d) a stressing mechanism for stressing the force store. The actuating device ensures that a flap closes precisely when a nominal filling level is reached, and does not open again even under intense fluctuation of the liquid level.

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.
