Hydraulic circuit for steering and working operations of working vehicle

摘要

The hydraulic cylinder has a steering control (3) with an arrangement for feed of an additional flow in the load signal line (19). The steering block (5) is controlled by a load signal and is mounted in a load dependent operating pressure valve (2',2"). The steering control has pressure lines (16,17) for the control block and a return line (18) which are parallel switched together over a load signal line (19) and connected to the adjuster for the adjuster pump. A non-return valve (20) can be mounted in the direction of the steering circuit.
