The larger barrel open end face supports a flat ring arranged perpendicular to the barrel axis. The said ring OD abuts, rigidly, upon the barrel side surface, the barrel being arranged opposite the first semi-casing flat ring. The housing inner chamber is formed by the aforesaid flat rings and the first semi-casing barrel side surfaces and those of the second semi-casing larger barrel.
