Abstract

The method involves recovering kinetic energy of rotation of a rotor of a secondary vacuum pump e.g. hybrid vacuum pump, in the form of electrical power so as to supply power to an information unit (4) to inform an operating state of leak detector to a user when a power supply of motor (11) of the pump is cut off. The recovered energy is used to power an electromagnetic valve (25) for returning a primary vacuum pump e.g. small oil sealed rotary vane, to atmospheric pressure and to re-establish the pressure at an inlet of the primary vacuum pump. An independent claim is also included for a leak detector.
