Abstract

The piston has a transmission housing (3). This contains two rotating hollow shafts (9), and the end sections of two parallel shafts (5,6) carrying the rotary pistons, are held in the hollow shafts. The transmission housing is removably fastened to the pump housing via a flange-like connection (2). The piston shafts are sealed relative to the pump housing via modular sealing units. The units have main cylindrical outer surfaces, so that they can be fitted into the pump housing or removed in one or the other axial direction.
