Abstract

In order to eliminate delivery-side pulses in a Roots compressor to the same degree for any rotational speed of the compressor, flow medium is introduced in a controlled manner from the delivery side D into the flow chambers formed by the pistons 1 and the cylinder wall 3, after closure with respect to the suction side, so that sub-pressure pulses are produced in the delivery-side flow chamber and the wave produced by these sub-pressure pulses cancels out the wave produced by over- pressure pulses caused on entry of the piston head of the one piston into the reduced-diameter region of the other piston.
