Tank closure with a self-locking closure apparatus arranged at the orifice rim of a pour-in socket-piece. The closure apparatus consists of a closure part and a pour-in opening which is closable by means of the closure part. Between the rim of the opening and a refueling nozzle to be introduced a gas outlet gap remains for the gases which escape when refueling the tank. A guide is provided for reception of the refueling nozzle. In order to free the exiting gases from fluid droplets, it is provided that the guide exhibits a reduced-scale segment closely surrounding the refueling nozzle. Exit openings are provided at the side of the reduced-scale segment which is placed toward the pour-in socket-piece, through which the gases pass out of the guide to the outside. Inlet openings are arranged at the side of the reduced-scale segment which faces away from the tank, through which the gases in the interior of the guide enter. A lead-apparatus is provided connecting the exit openings and the inlet openings in a moderate flow.

A tank closure which is comprised of (A) self-sealing closure apparatus for a fuel tank arranged at the orifice rim of a pour-in socket-piece (1), which closure apparatus consists of a closure part (2) and a pour-in socket piece having a pour-in opening (3) which is closable by means of the closure

A tank closure which is comprised of (A) self-sealing closure apparatus for a fuel tank arranged at the orifice rim of a pour-in socket-piece (1), which closure apparatus consists of a closure part (2) and a pour-in socket piece having a pour-in opening (3) which is closable by means of the closure part (2), and which is large enough to leave a gas outlet gap between the rim of said opening and a refueling nozzle (4) to be introduced for the gases which escape when refueling the tank, said pour-in socket piece having no means of escape for said gases other than said gas outlet gap; and (B) a guide means (5) for reception of the refueling nozzle, comprising, in combination with said closure apparatus, lead-apparatus for guiding gases, which have escaped through said gas outlet gap, through a moderate-flow passage to the outside of said refueling nozzle, said guide means (5) having a reduced-scale segment (5a) closely surrounding the refueling nozzle (4), said reduced-scale segment (5a) having at the side thereof which is placed toward the pour-in socket-piece (1), an unobstructed exit opening through which the gases freely pass out of the guide means (5) to the outside, said reduced-scale segment (5a) having at the side thereof which faces away from the tank inlet openings (7) through which the gases enter into the interior of the guide means (5), said lead-apparatus connecting the exit opening and the inlet openings so as to confine the flow of gases which flow through said exit opening to an unobstructed moderate flow from said exit opening to said inlet openings.
