ABSTRACT:
In a dispenser nozzle having, a main body portion, a filling tube projecting from one end of said main body portion, and a liquid flow passage extending through said main body and said filling tube, the filling tube being adapted to be located within the open end of a neck of a fuel storage tank of a vehicle or the like, a control valve mechanism for controlling the flow of liquid through said liquid flow passage, said mechanism including a valve operating mechanism and latching means for releasably engaging said valve operating mechanism to render said valve operating mechanism operative when engaged by said latching mechanism and inoperative when released by said latching mechanism, the improvement of sensor means mounted on said nozzle and disposed adjacent said filling tube, said sensor means communicating with said latch means to release said latch means with respect to said valve operating mechanism to render said valve operating mechanism inoperative when said filling tube is now disposed in a predetermined operative relationship within a fuel storage tank, said sensor means cooperating with said fuel storage tank when said filling tube is located in a predetermined operative relationship with respect to a fuel storage tank to permit said latch means to move to a position to engage said valve operating mechanism to render said valve operating mechanism operative to permit the flow of liquid through said liquid flow passage into said tank.
