Abstract:
1. A filler neck for a diesel fuel tank, the filler neck comprising: a filler neck housing; a pair of control levers mounted pivotably on control lever pivots in the filler neck housing and configured such that on insertion of a nozzle of a diameter greater than a minimum diesel nozzle diameter into the filler neck, the control levers pivot in an outward direction, and do not pivot in an outward direction on insertion of a nozzle of a diameter less than the minimum diesel nozzle diameter; a control spring attached respectively at both ends to the control levers and configured such that the pivoting in an outward direction by the control levers leads to a defined greater change in position for at least one control portion of the control spring; a blocker lever mounted on a blocker lever pivot in the filler neck housing and pivotable between a blocking position which prevents insertion of a nozzle beyond the blocking lever and an unblocking position in which insertion of a nozzle beyond the blocker lever is allowed; a blocker latch configured for movement between an immobilizing position and a non-immobilizing position, and which interacts with the blocker lever such that in the immobilizing position the blocker latch immobilizes the blocker lever in its blocking position, and in the non-immobilizing position does not immobilize the blocker lever in its blocking position whereby the blocker lever may pivot into the unblocking position; a blocker latch spring configured to load the blocker latch towards the immobilizing position, wherein the control spring is configured to permit movement of the blocker latch out of the immobilizing position into the non-immobilizing position by the defined greater change in position of at least the control portion of the control spring, wherein the blocker lever if not immobilized in the blocking position is configured to pivot into the unblocking position through the insertion of a nozzle.
