Abstract

A pump, for pumping a gas, having a rotor 10 and a stator 20 one of which has at least one liquid opening 12 from which is driven a stream of liquid that forms a liquid blade, or fluid vane, between the rotor and the stator such that, gas is confined and driven along a pumping channel (38, fig.5) by the relative rotation of the rotor and stator from an inlet 52 towards an outlet 54 and a cross-sectional area of the pumping channel increases from the gas inlet to the gas outlet. The radial width and/or axial width of the pumping channel, which may be helical (fig.2) or spiral, can increase towards the outlet as too can the size of the liquid opening and hence the volume of the liquid blade. The liquid opening may be a slit which is arranged as a helix around the rotor, or it may be formed of multiple smaller openings in a line. The pump can have a seal (32, fig.5) and be used as a vacuum pump that compresses the gas by having a decreasing cross-section of available space in the pumping channel even when the channel increases in cross-section.
