Abstract
An axial piston micropump is disclosed, having a cylinder drum, in which several cylinders are provided a swash plate, with respect to which the cylinder drum is rotatable. It is desirable for such a micropump to have a small displacement combined with a long service life and in which the displacement or delivery volume can be achieved with great accuracy. For that purpose, at least two cylinders are provided, of which at least one is in the form of a working cylinder which has an associated working piston, while at least one other cylinder is in the form of a balance cylinder and has an associated balance piston.
