In this coaxial double pump, to achieve a higher performance, a simple construction making the exchange of wearing parts easier and a low generation of noise, the working cylinders, the inlets and outlets of which open into a common suction and delivery channel (11, 12), are arranged concentrically in two rotating drums (7, 8) keyed on a common shaft (4), the working cylinders of one drum being arranged preferably angularly offset relative to the working cylinders of the other drum. The pistons (13) of the working cylinders are moved by two pivoting discs (5, 6) or, in a special exemplary embodiment according to Figure 2, by only one centrally arranged pivoting disc (20), the inclination of which can be changed continuously. <IMAGE> |
