Fuel dispensing nozzle having hold-open clip with lockout mechanism

摘要

A fuel dispensing nozzle is disclosed and includes a main body portion containing a fuel passageway and a main valve controlling the flow of fuel through the fuel passageway. A lever extends from the body portion which is operable by the hand of a user holding the nozzle to open the main valve to allow fuel flow through the nozzle and a lever guard is attached to the body and extends around and under the lever. A hold-open clip is pivotally mounted to the lever guard. The lever includes notches which are positioned relative to the hold-open clip so that when the hold-open clip is rotated by the user into its operative position it may engage a notch in the lever and hold the lever in a position where the main valve is opened to allow fuel flow without requiring the user to continue to hold the lever. A removable lockout member is attached to the lever to prevent operation in the automatic hold-open mode by preventing engagement of the hold-open clip with a notch in the lever. The lockout member includes a retention device to prevent manual removal of the lockout member once it is attached to the lever.
