Abstract

The invention relates to a positive-displacement machine for compressible media, having at least one spiral-shaped impeller chamber arranged in a slot-like manner in a fixed casing and having a strip-like or tongue-like impeller (displacer), which is likewise fashioned in the manner of a spiral and is retained in each impeller chamber, eccentrically drivable in such a way that each of its points carries out a circular motion delimited by the peripheral walls of the impeller chamber. The curvature of the impeller is to be defined in such a way, compared to that of the impeller chamber, that the impeller nearly touches the inner and outer peripheral walls of the impeller chamber at at least one sealing line, which continuously advances as the impeller is driven. In order to achieve improved sealing between the individual working chambers formed on one side of the impeller, the impeller is to have spaced groove-like or channel-like recesses, which essentially run transversely to the circumferential direction, at its sides facing the peripheral walls of the impeller chamber.
