The compressive force of the 3-chamber cylinder is determined by the piston areas (52 and 53) in the chambers a, b, and c. At the same time openings (59 and 55) are open. The tractive force of the 3-chamber-cylinder is determined by the piston areas (52 and 53) from the sight of chamber c. At the same time the opening (51 and 58) are open. If the tractive force and the compressive force shall be equal, so the liquid or gas must be pumped into chamber c with double pressure, because this working stroke is executed only from one chamber = c and not as in the case of the compressive force from two chambers. |
