Abstract
A vacuum generator driven by compressed air and arranged to supply vacuum to a vacuum gripper element, wherein a chamber () is associated with the vacuum generator and arranged to be brought in flow connection () with the vacuum gripper element via a valve () which is actuated by overpressure accumulated in the chamber to open the connection () to the vacuum gripper element in order to discharge the overpressure to the vacuum gripper element in result of interruption of the compressed air flow (P). The vacuum generator is characterized in that the chamber () in addition includes a flow connection () with the ambient atmosphere, and in the additional flow connection () a one-way valve () which is arranged to open the connection () with the atmosphere in result of the air pressure in the chamber () falling below the atmospheric pressure.
