Abstract

The invention relates to a rotary piston (20, 21) for a rotary piston pump, comprising a piston main structure (122), comprising a hub structure (210) with a bearing circumferential surface which extends around a rotational axis of the rotary piston, and at least two piston vane structures (220 a-d) which are connected to the hub structure, wherein the piston main structure is formed from a first, preferably metallic, material, and is preferably enclosed radially on the outside preferably with a second material which is different from the first material, in particular an elastomer material, characterized in that at least one cavity (126 a-d) which is preferably gas-filled is formed in each case in a, preferably each, piston vane structure, which cavity is enclosed by a piston vane wall of the piston main structure and possibly also by an outer circumferential surface of the hub structure and which is free from elastomer material.
