Abstract (en)
The device has a two-way-circular-pressure balance (W2) provided between a pump (8) and a tank (T), a pre-loaded pressure balance (W1) for partitioning the pump delivery flow, and a load compensation system (L). The balance (W1) is designed as two-way pressure balance and is arranged, relative to the pump, parallel to or upstream of the balance (W2) at an input section (E) of the device, where the section is designed as block module.
