ABSTRACT:
A fluid machine comprises two rotors, one rotor having at least one projection which engages within a recess within the other rotor. During operation, fluid passes between the first rotor and a peripheral surface of a working chamber within which the rotors are mounted. A fluid inlet and a fluid outlet are so arranged as to face generally in the direction in which the fluid moves around the first rotor. Pressure-equalization passages are provided in the rotors, and extend between the opposed axial faces of the rotors whereby, to equalize the fluid pressure at the axial faces. The machine may be used as a pump for water and other liquids.
