Abstract
A liquid dispensing nozzle (10) with a pump pressure responsive automatic shut-off mechanism. The nozzle (10) comprises a body (12) with an internal passageway (13) therethrough defining an inlet port (14) for being connected to a dispensing pump and an outlet port (16). A main valve (18) is mounted in the body (12) for selectively opening and closing the passageway (13) to the flow of liquid, and a latch mechanism (29) is provided for selectively closing, and prohibiting the opening of, the main valve (18). The nozzle (10) further comprises automatic shut-off mechanism for releasing the latch mechanism so as to close, and prohibit the opening of, the main valve when supply pressure from the dispensing pump falls below a preselected value. Such automatic shut-off mechanism includes an actuator member ( b 43) operatively associated with the latch mechanism (29) and movably responsive to fluid pressure within the passageway between the inlet port (14) and the outlet port (16) reaching a preselected value.
