ABSTRACT:
A machine, in particular a working machine for the compression and conveyance of fluids, comprises a cylinder (2) and a thin-walled annular piston (4) arranged eccentrically with respect to the cylinder (2), with the piston being in flat contact either inside or outside with a cylinder wall (8). The cylinder (2) or the cylinder housing, contains a parting element (12) whereby a suction chamber (33) is separated from a pressure chamber (35) between the cylinder and the annular piston (4) and whereby by means of a rotating body a rotating motion may be imparted to the annular piston (4). The annular piston (4) is to be exposed to low alternating stresses and between the cylinder (2) and the annular piston (4) a low local surface pressure is to be achieved, while assuring a reliable contact in the rolling range (A). It is proposed according to the invention to provide an essentially circular configuration of the annular piston (4), with the deviation from the circular amounting a maximum of 5% of the piston diameter and that further the center (26) of the annular piston (4) with the rotating body be arranged offset in the direction of the rolling range (A) from the center (28) of the cylinder (2) by the sum of the eccentricity (e) and the deformation (d). The eccentricity here is equal to one-half of the difference of the diameters of the cylinder (2) and the annular piston (4), while the magnitude of the rolling range (A) is determined by the deformation (d).
