ABSTRACT:
In a displacement machine for compressible media, having four delivery spaces arranged in a fixed housing, each housing half (7) has two delivery spaces (11, 11') which are offset by about 180.degree. with respect to one another and extend in a spiral shape from an inlet (12,12') to an outlet (13). Each delivery space is allocated a displacement body which fits into the latter and is held, as a spiral-shaped strip (3,3') perpendicularly on a disk-shaped rotor (1) which can be driven eccentrically with respect to the housing. For the guidance of said rotor a second eccentric guiding arrangement (10) arranged at an interval from a first eccentric drive arrangement (9) is provided in the housing. For the flexible accommodation of any length differences between delivery space and displacement body, the guide eye (5) of the eccentric guiding arrangement is connected to the disk-shaped rotor (1) via a stem (29) which is formed as a tangential extension on the inlet-side end of one of the spiral-shaped strips (3).
