摘要

The arrangement comprises a first sliding valve (64) with a control inlet working with the control pressure and a system pressure inlet working with the pressure of the system. There are also two outlet areas, each of them either connected to the control inlet or the system pressure inlet while the other is connected to the complementary device and vice versa, depending on the pressure present at the control inlet. A valve arrangement (66, 68) for a selective operation of the shift cylinders (SZ1, SZ8) is attached to the outlets of the sliding valve (64).
