Abstract
A hydraulically driven forging machine with four radially arranged working cylinders has piston pumps disposed as individual pumps about the forging machine with all pump-end pipe connections located on the horizontal center plane of the forging machine, so that all pipe conduits leading to the working cylinders are equal in length and as short as possible in order to equalize and minimize stroke volume losses in the four working cylinders which result from the compressibility of the fluid pressure medium.
