    Abstract: A compressor design includes a male rotor (10) having one or more helical lobes (12) and a female rotor (14) having one or more helical grooves (16). The male rotor is mounted on a first shaft and the female rotor is mounted on a second shaft. The male rotor is positioned in a first section of a chamber and the female rotor is positioned in a second section of the chamber. Fluid enters the chamber at an inlet, and when the rotors are driven, the lobes of the male rotor fit into the grooves of the female rotor, causing compression and movement of the fluid towards an outlet or discharge end where the compressed fluid is discharged. The configuration of the lobe and groove helix, the lobe and groove profile, and the outer diameter of the rotors can be varied in different combinations to form different rotors.

    Abstract: An eccentric screw pump with an annular outer part (10; 40; 74) and an inner part (12; 42; 72) arranged therein has an interior of the outer part (10; 40; 74) and an exterior of the inner part (12; 42; 72) tapering in a complementary manner towards an axial end (16; 46; 70). In the axial direction (X, W), the inner part (12; 42; 72) and the outer part (10; 40; 74) are movably received in relation to each other and the inner part (12; 42; 72) and/or the outer part (10; 40; 74) are configured in such a manner that pressure applied to the pressure side of the eccentric screw pump generates a force that acts upon the inner part (12; 42; 72) axially to the direction in which the inner part (12; 42; 72) tapers and/or a force that acts upon the outer part (10; 40; 74) in an opposite axial direction.

    Abstract: A single screw compressor structure includes a screw rotor and a casing. The screw rotor has a plurality of helical grooves formed in an outer peripheral surface thereof. The a casing houses the screw rotor. The screw rotor includes a main tapered portion having a tapered outer diameter that becomes larger from an intake side toward a discharge side of the screw rotor, and a reversely tapered portion that is located on a downstream side of a maximum outer diameter portion of the outer surface and on the discharge side of the main tapered portion. The reversely tapered portion has a reversely tapered outer diameter that becomes smaller as the reversely tapered portion extends away from the maximum outer diameter portion.
