An apparatus for cooling-water extraction for a robot installation plate is characterized by an adjustable extraction volume. The extraction volume is achieved by a sufficiently large extraction cylinder which has a maximum extraction volume, wherein the extraction volume is adjusted by a mechanical stroke limit of a piston located in the extraction cylinder. In at least one embodiment, the mechanical stroke limit is realized by an adjustment screw that is on or in the extraction cylinder. The adjustment screw forms a stop that provides an end position limit or stroke limit of the piston.

An axial piston machine includes a housing, an actuating piston, and a closing screw. The housing includes a cylinder bore, a recess, and a fluid channel. An end of the bore open to an outside of the housing has an internal thread. The recess is located in a region of the internal thread, and is deeper than a thread depth of the internal thread so that a floor region of the recess is free from thread turns. The piston is linearly moveable in the cylinder bore, and is configured to adjust a displacement volume of the machine. The screw is screwed into the internal thread so as to form a closed chamber between the piston and the screw. The fluid channel opens into the floor region of the recess, and is fluidically connected to the cylinder chamber.
