Abstract

In a positive displacement machine for incompressible media, with a working chamber (4) located in a stationary housing (1, 2) and having the configuration of a circular slot, a circular displacer body (8) located in said working chamber, is being held on a disk shaped rotor (3) driven eccentrically relative to the housing. The displacer body contacts the inner and outer circumferential walls of the working chamber at least one sealing line continuously progressing in operation, whereby the medium is conveyed from an inlet (6) to an outlet (7). The inlet is separated from the outlet by a land (5) extending radially in the working chamber (4). For the guidance of the displacer body relative to the housing an Oldham (cross keyed) coupling (9, 10) is provided, and for the circular drive of the displacer body a wobble rod (12, 12') is connected with a driving crank drive (13). In the area of the land (5) the inner and outer work spaces (27, 28) communicate with each other at the inlet ( 6) and the outlet (7). The displacer body (8) and the working chamber (4) have a circular configuration over the overwhelming part of their configuration. The ends on the inlet and the outlet sides of the displacer body and the working chamber, in an angular zone (.alpha.) of maximum 30.degree., have significantly smaller radii of curvature than that of the overwhelming circumference.
