Abstract
A gasoline pump comprises a housing having a vapor recovery nozzle mounted on a bracket. An actuating lever is pivotally mounted on the housing for movement between "on" and "off" positions. The nozzle comprises an annular elastomeric face seal adapted for sealing engagement over a fill neck of a vehicle and a spout extending through the face seal for disposition within the fill neck for gasoline filling purposes. A hood assembly is secured on the housing to cooperate with the bracket to mount the nozzle and to fully enclose and protect the face seal thereof. The hood assembly preferably comprises a metallic plate secured to the housing of the pump and a generally wedge-shaped hood member secured to the plate. An elastomeric gasket is secured to the lower free edges of the hood member to prevent damage to the face seal of the vapor recovery nozzle upon insertion thereof into the hood assembly. The bracket may be mounted on the housing, on the actuating lever or, on the hood assembly. The pump is arranged so that the nozzle cannot be mounted on the bracket to dispose the stem thereof within the hood assembly, unless the actuating lever is pivoted to its "off" position.
