Further, a displacement mechanism having a displacement nut which is displaced under a driving action of the rotary drive source is disposed in the interior of the housing. A bellows is interposed between a tubular body connected to the displacement nut and a first block of the pump head, wherein the interior of the bellows also is filled with the indirect medium, which is made up from an incompressible fluid.
