Abstract
A capping assembly for use in a fuel storage tank provided for a motor vehicle and the like includes a diaphragm positioned inside the assembly so as to divide an internal space into two spaces. One space communicates with the inside of the tank and is separated from the other space which communicates with the outside of the tank. The assembly further includes a valve arrangement, comprising a needle valve and a valve seat, which cooperates with the diaphragm so that the two spaces can be selectively communicated with each other in response to a relative change of pressure inside the tank with respect to a predetermined pressure.
