<p>A tire curing device (1) wherein an upper half mold (16) and a lower half mold (17) define a toroidal chamber (22) for accommodating a tire to be cured and constituting a portion of a closed circuit (115) for a batch charge of a heat exchange fluid, the tire being cured by circulating the fluid along the circuit (115) by means of an impeller device (84); the fluid being heated by a heating device (94) as it flows along a return conduit (117) having an annular section increasing towards the impeller device (84) and coaxial and aligned with the annular inlet of the same; the fluid being fed to the toroidal chamber (22) along a delivery conduit (116) having an annular section and so shaped as to exert at least one compression-expansion action on the fluid. <IMAGE> <IMAGE></p> |
