Abstract

The oscillating positive displacement vacuum pump (1) has a drive chamber (8), which is sealed automatically for surrounding atmosphere extensively, such that a pressure sensor (9) is arranged at the drive chamber. The pressure is measured in the drive chamber. A control signal or switch-off signal is generated by the pressure sensor, while measuring a low pressure in the drive chamber corresponding to a warning signal from an evaluating circuit (10).
