In the invention, the conventional gear pump with two gears, in which one gear drives the other gear via the meshing engagement and the contact between the gear teeth, is modified to the effect that double gear spindles are used so that each gear is driven independently with one and the same torque, and that the gears are closely adjacent to one another, with the result that the gears interlock but in essence do not touch one another. |
