Abstract
A closure assembly particularly useful as a radiator cap for the radiator filler tube of a motor vehicle including bayonet connectors for removably fastening the assembly to a filler tube is formed with a vacuum valve and an excess pressure or relief valve formed on an inner cap assembly of the closure assembly, with the inner cap assembly being formed with a pair of telescopically slidable parts and with a compression spring which is preferably constructed as a cup spring in order to press one of the telescopic parts relative to the other to effect sealing engagement with the seat of the filler tube, the force of the cup spring being greater than the closing force of a load spring which is provided for the excess pressure or relief valve.
