Hydraulic control device

摘要

The arrangement has an inlet pressure balance (5) provided in a pressurizing medium flow path between a pump (4) and one of two consumers e.g. traction drives. A power-beyond-connector (64) branches in the pressurizing medium flow path between the pump and the inlet pressure balance. The inlet pressure balance is charged in a closing direction by a force of a spring (72) and in an opening direction by a pressure on an inlet (P). The balance is charged in the closing direction additionally and selectively by a largest load pressure or by a pressure above the largest load pressure.
