Open the CIPO recordAbstract From the Canadian patent
The invention intends to automatically repeat a few times of additional fuel delivery which is necessary for full tank delivery after false fuel level detection which is inevitably caused by fuel bubbles or splashes. It is made possible essentially by making a valve seat for a main valve longitudinally movable and providing control means and a mechanism so that despite of a trigger being in the actuated position the valve is opened when bubbles or splashes disappear.
