Abstract
An installation for quenching a glass hollow body includes a plurality of external nozzles and an axial nozzle. The plurality of external nozzles are positioned around a main axis. Each of the plurality of external nozzles includes an axial slot configured to direct an air jet towards the main axis. The axial nozzle is aligned along the main axis and includes a shape configured to form an internal air jet forming a ring with an opening at a center thereof in a plane transverse to the main axis. The axial nozzle forming the internal air jet positioned substantially external to and above the bore.
