<p>The installation (1) has an enclosure (7) e.g. cylinder, with a variable volume chamber (8) connected to a pressurized thermoregulated fluid circuit (5). An auxiliary fluid generating unit (9) is connected to the enclosure such that the chamber is subjected to back pressure of an auxiliary fluid. The unit and the enclosure are arranged such that the back pressure is reduced to a minimum pressure and thermoregulated fluid e.g. oil, is relaxed in the chamber till the pressure of the thermoregulated fluid attains atmospheric pressure, before a blowing mold (3) is detached from a mold support (2).</p> |
