Abstract
The male (3) and female (4) rotors are located in mechanical radial bearings (9,10) and axial bearings (11,12). The male rotor has screw-line running lobes (5) with intermediary tracks. The lobes are positioned outside the dividing circle of the rotor, and have flanks with convex geometry. The female rotor is similarly formed with its lobes inside its dividing circle and flanks with concave geometry. The lobes and tracks of the two rotors are engaged with each other, forming V-shaped work chambers. - Magnet components (14,16) are provided which without mechanical contact exert an axial force on at least one of the rotors, i.e. the female, and the force is directed in the same direction as the axial force exerted on the rotor by gas pressure. One of the magnet components (14) is fitted on the female rotor, and the other (16) on the housing (2), both working in a repellant manner.
