Abstract
A piston for a compressor has a first end subjectable to pressure and intended to be directed toward a first volume of the compressor, and a second end subjectable to pressure located opposite the first and intended to be directed toward a second volume of the compressor. The first and the second volume are interconnected via a connecting line. The first end is in the form of a full-surface-area full side. The second end is in the form of an annular, stepped side. On the second end, the piston carries a sealing arrangement, which seals the first volume with respect to the second. An annular seal body, in the form of a sealing sleeve, is retained in a pressure-tight manner, via a profile base, on the stepped side, between a step-side piston ring arranged on the second end and a compression-volume-side retaining ring.
