Abstract
There is described a vacuum pump (1) having an outer casing (3) having at least one opening (5) connected to an environment in which a vacuum is to be formed; and a rotor (7) supplied with an operating liquid, and mounted to rotate about an axis (A) inside the casing (3) to produce, by movement of the operating liquid, a vacuum in the environment connected to the opening (5); the rotor (7) having generating means (50) for generating a screw-shaped stream of operating liquid to draw gaseous fluid by suction though the opening (5).
