Abstract

The invention discloses a hydraulic machine assembly having at least one motor and at least one pump driven by the same. The motor and the pump each have a piston guided in a cylinder. The cylinders and the associated pistons can be moved relative to one another, wherein either the cylinder or the piston can be moved in the motor and in the pump. The moving design elements of the motor and the pump are connected. A stroke of the motor thus accompanies a corresponding delivery stroke of the pump, wherein the pump then delivers coolant and/or lubricant.
