Cast nozzle having improved latch and shut-off mechanism

摘要

A fluid dispensing nozzle for gasoline or the like includes a cast body having an inlet, an outlet, a valve seat between the inlet and the outlet, and a hand guard. Mounted in and on the cast body are a poppet valve for controlling flow through the valve seat, a spring urging the poppet valve closed, a valve stem extending into the poppet valve, a cast lever engaging the valve stem for manually urging the poppet valve away from its seat, and a high-level shut-off means for disabling the lever. The high level shut-off means includes a plunger to which the actuating lever for the nozzle is pivoted, a latch pin, latching balls, and a cylindrical sleeve which acts as a guide for the plunger and as a stop for the latching balls. A hold-open clip is pivoted to the integral hand guard and engages latching teeth on the lever. Release of the high-level shut-off causes a heel portion of the lever to force the clip out of engagement with the teeth.
