ABSTRACT:
This invention relates to a check valve device for a fuel pump nozzle comprising a stopper having a stem slidably extending through a bore of a support member which is securely engaged within the passage of the nozzle near the dispensing end thereof. The stopper has a plug member offset and fixedly attached to the stem to close off the passage of the nozzle with the urging of a spring mounted about the stem between the support member and a stop member which is securely attached about the stem near the opposite end thereof. The check valve device prevents liquid such as gasoline from dripping or escaping out the dispensing end of the nozzle when liquid is not being dispensed through the nozzle.
