Abstract:
The present invention relates to a multi-stage vacuum equipment, preferably a two-stage equipment, whose normal operation requires different pressures to be set, wherein the pressure variation may be achieved by a Shape Memory Alloy (SMA) wire movement of a suitable element. The invention further discloses a method for operating said multi-stage vacuum equipment controlled by a SMA actuator.
