Abstract In order to avoid overfilling of fuel to small internal combustion engines a nozzle is presented which automatically closes the flow when the tank is almost full. The nozzle is put on the fuel container which communicates with the surroundings by an air conduit through the nozzle, constituted of two sleeves, an outer one (13) and an inner one (14) and a bushing (11). The fuel passes the inner sleeve, whose outer end has a valve body (15). At rest the outer sleeve presses against the body and then the nozzle is closed. When the nozzle is put into a filling hole, the spring-biased outer sleeve is pushed back and allows the fuel to pass through the inner sleeve to the tank. When the fuel reaches the outer end of the nozzle the air inlet to the container is closed and the flow stops. When the nozzle is pulled out of the hole it is automatically reset into the rest position.

Independent Claim
266 words
A fuel dispensing nozzle for a receiver having a fastening member for connecting said nozzle to an outlet of a fuel container, said fastening member having a sleeve to couple said nozzle to said outlet comprising: a fluid passageway extending through said nozzle, a valve member, biasing means to bias said valve member to a position in which flow through said passageway is prevented, and said valve member being openable against the action of said biasing means by pressing the nozzle into a filling hole, an air conduit in the form of a channel extending along the passageway through the nozzle to be opened and closed by the said valve member simultaneously with the passageway, said passageway being provided with an end opening in the container below the fuel surface in the receiver when at least a part of said nozzle and said passageway are submerged in the fuel in said receiver, said sleeve being threaded at both ends whereby either end may be screw-threaded on said outlet of the fuel container and a cap adapted to be removably attached to one end of said nozzle whereby said nozzle is adapted to be turned approximately 180 degrees relative to its longitudinal axis so that the opposite end thereof is connected to said fuel container to thereby function as a closure for said fuel container whereby fuel flows freely from said fuel container by gravity when one end of the nozzle is connected to said container and fuel flow from the container is prevented when said opposite end of the nozzle is connected to said fuel container.
