An artificial heart, comprising an energy storage device, an actuator device and two pumping chambers, each with an inlet opening and an outlet opening, wherein each pumping chamber is bounded by at least one flexible wall and one rigid wall and the volume of each pumping chamber can is variable by deformation of the flexible wall by means of the actuator device, whereby the flexible wall, starting from a suction position in which the volume of the respective pumping chamber is at a maximum, can be converted to a pumping position in which the volume of the feed chamber is at a minimum by means of the actuator device, wherein the inlet opening and the outlet opening of each pumping chamber each have a non-return valve and the non-return valves can be reciprocally in an opened and a closed position, wherein the actuator device is located between the pumping chambers.
