Abstract
An attitude sensing arrangement for triggering a shutoff mechanism on a fuel dispensing nozzle comprising a rolling element placed inside a non-cylindrical chamber that is sealed with a plug such that the rolling element may move freely inside the chamber. A vacuum sensing path passes from a sensing port in the nozzle spout, through a vacuum sensing tube, into the non-cylindrical chamber, and into a venturi-generated vacuum chamber. The attitude sensing arrangement is configured such that the rolling element blocks a shutoff port in the non-cylindrical chamber when the nozzle is raised past a certain shutoff angle. When the vacuum sensing path is blocked by the rolling element in this manner, the shutoff mechanism closes the main fuel valve.
