<p>The unit has pressure supply units (10, 16) comprising leads (2, 6) arranged along a guidance direction. A first return line (4) extending from a first terminal (A) to a tank (T), and a second return line (8) extending from a second terminal (B) to the tank are arranged on parallel valves (14, 20, 26, 28, 30, 32, 36, 38) e.g. solenoid operated switching valves. The valves are closed when the valves are not in an operating mode. Return springs are arranged in the valves. The valves are pulse width-modulated and actuated by electronic control devices.</p> |
