摘要

The system (1400) has pressure control magnetic valves (140) with inputs communicating with sources for a hydraulic fluid. A logic valve has an inlet connected with an outlet of another logic valve. A gear wheel selection piston- and cylinder assembly has a connection connected with an outlet of the former logic valve and another connection connected with a connection of a third logic valve. Another gear wheel selection piston- and cylinder assembly has a connection connected with another outlet of the former logic valve and another connection connected with a connection of the former valve.
