Cooling system for cooling a rotary mount, a rotary mount including such a system, and a machine, in particular a blow-molding machine, including such a system and such a mount

A machine for fabricating receptacles by blow-molding, the machine comprising a rotary mount (2) and a circuit for passing a cooling fluid, said rotary mount (2) carrying a carousel of a receptacle blow-molding machine, said mount comprising two rings (4, 7) capable of rotating relative to each other, each ring having a raceway, the mount further comprising a bearing device (8) constituted by rolling bodies interposed between the two raceways, the machine being characterized in that a cooling device is provided comprising at least one cooling circuit (9) pressed against one of the two rings (4, 7) of said mount (2), in that there are provided measurement means (19) for measuring the temperature of the mount (2), and control means (21) for controlling the flow of cooling fluid as a function of the difference between the temperature of the mount (2) and a reference temperature, the cooling circuit (9) of the mount (2) being connected to the cooling fluid circuit of the machine,

• in that the cooling circuit (9) comprises at least one stage (10H;
• 10L) having at least one arcuate duct element (10a, 10b;
• 10c, 10d);
• and
• in that the machine comprises at least two stages (10H;
• 10L), and the cooling fluid is caused to circulate in two opposite directions from a given stage of the circuit to the stage which is contiguous therewith.
