Vacuum generator device

There is a vacuum producing device (1) is proposed which has a membrane-Polymeraktuator (5), which is a process that runs in membrane form electroactive Polymeraktuator and defining a variable volume pressure chamber (18). The membrane Polymeraktuator (5) is biased by biasing means (14) such that it expands when activated, and causes a change in the volume of the vacuum chamber (18) so that in a negative pressure can be generated.
