Abstract

A system for automatically cutting off the flow of fuel from a robotic refueling nozzle assembly is disclosed. The fuel cut off system comprises first fuel cut off member having a sensor coupled to the robotic refueling operatively associated with the venturi vacuum sensor and a fuel shut off valve disposed upstream from the variable venturi vacuum generator, the fuel shut off valve controlled by the computer. The first fuel cut off member includes a primary high level cut off subsystem having a venturi vacuum normalization software and a software algorithm to compare pre-set optimal normalized venturi vacuum levels with sensed normalized venturi vacuum during refueling and to cut off fuel flow via the fuel shut off valve if a substantial negative pressure spike is detected. Also included is a fuel splash back stabilizing subsystem.
