Abstract:
An aggregate of pressure medium cylinders, comprising:a plurality of first-type cylinders, each first-type cylinder having a first-type cylinder portion with a longitudinal axis and a first-type piston with an outer end, wherein the first-type piston is in displaceable relation with the first-type cylinder portion along the longitudinal axis and the outer ends of the first-type pistons are disposed in the same direction and rigidly connected to each other; a plurality of second-type cylinders, each second-type cylinder having a second-type cylinder portion with a longitudinal axis and a second-type piston rod having an outer end, wherein the second-type piston rod is in displaceable relation with the second-type cylinder portion along the longitudinal axis and the outer ends of the second-type pistons are disposed in the same direction and rigidly connected to each other; and first and second common power-transmitting slides centrally arranged between the first-type and second-type cylinders and movable along a common axis, wherein the first-type and second-type cylinders are arranged in an alternating annular formation about an aggregate axis, the first-type and second-type cylinders portions are rigidly connected to each other in a longitudinally parallel manner, the outer ends of the first-type and second-type pistons are oppositely directed, the first-type pistons are connected to the first common power-transmitting slide, and the second-type pistons are connected to the second common power-transmitting slide.
