Abstract
An apparatus, particularly for compressing and conveying fluids, comprising a rotor (1) and a thin-walled rotary sleeve (7) which is rotatably arranged eccentrically with respect to the axis (M1) of the rotor and which is in surface contact with the surface of the rotor throughout a predetermined angular range (.phi.). At least one separator slide (12) is provided between working chambers (S, D) the volumes of which vary when the rotary sleeve rotates. The apparatus is constructed such that the fluid throughput and the speed of rotation can be increased compared to conventional devices, so that a device of given capacity may have smaller dimensions and a lower weight. To achieve this it is proposed that the rotary sleeve (7) be supported in a bearing support (110) by at least one bearing (125) and be pressed thereby against the circumferential surface of the rotor (1), and that the rotor (1) be rotatably mounted around a control tube (3) and contact the inner surface of the rotary sleeve (7) in the predetermined angular range (.phi.). The rotary sleeve (7) cylindrically embraces the rotor (1) in the predetermined angular range (.phi.) and is driven by the rotor through frictional engagement.
