Abstract (en)
[origin: EP2333336A2] The machine e.g. piston pump (10), has cylinders (12a, 12b), and cylinder heads (18a, 18b) for closing an opening of the cylinders. Pistons (22a, 22b) are arranged partially within the cylinders, where the pistons are arranged movably in a longitudinal direction relative to the cylinders and the cylinder heads using connecting rods (28a, 28b). The pistons have an opening that runs in the longitudinal direction. A partial area of guiding elements (30a, 30b) is arranged within the opening of the pistons, where the guiding elements are firmly connected to the cylinder heads.
