1. An installation for quenching a glass hollow body, the quenching installation comprising:
a plurality of external nozzles positioned around a main axis, wherein each of the plurality of external nozzles comprises an axial slot configured to direct an air jet towards the main axis; and
an axial nozzle aligned along the main axis and comprising 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,
wherein the axial nozzle forming the internal air jet is positioned substantially external to and above a bore extending along the main axis,
wherein the shape comprises an axial core connected by radii to an external contour.
