ABSTRACT:
An improved liquid dispensing nozzle (10) for dispensing a liquid such as fuel, from a dispensing pump. The improved dispensing nozzle comprises a body (12) defining an internal passageway (13) provided with an inlet port (14) for releasably connecting the nozzle (10) in fluid communication with a dispensing pump and an outlet port (16) for carrying a spout assembly (17) for selectively directing the flow of liquid from the nozzle (10). A main valve (18) is mounted within the body (12) between the inlet port (14) and the outlet port (16) and is provided with an operating lever (32) for selectively opening the main valve (18) to allow liquid to be discharged from the nozzle (10). The nozzle (10) further comprises ball-latch mechanism (25) for selectively disabling the operating lever (32) in order to close, or prohibit the opening of, the main valve (18) and further comprises first automatic shut-off mechanism (34) for selectively releasing the ball-latch mechanism ( 25) so as to disable the operating lever (32) when the supply pressure from the dispensing pump falls below a preselected value.
