Installation (1) for blow molding hollow bodies, comprising at least one mold carrier (2) to which a removable mold (3) can be connected via fluid connection means (4), at least one pressurized temperature-controlled fluid circuit (5) passing through the carrier and mold, and automatic circuit (5) shutoff means provided in the carrier (2); which circuit (5) has a fluid connection to at least one chamber (8) having a variable volume that depends on an external pressure applied to said chamber (8) by means (9) for generating an auxiliary fluid at a pressure that is adjustable between the pressure of the temperature-controlled fluid and atmospheric pressure, by means of which the pressure of the pressurized temperature-controlled fluid can be reduced in said chamber (8) by decompression. |
