<p>Hydraulic control arrangement regulates a constant low pressure in a flow pipe (16). A run-off pressure balance (60) is impinged by a constant pressure in the flow pipe in the opening direction. Preferred Features: The constant pressure is adjusted using a pressure limiting valve (48) adjusted to a low pressure and connected to a call circuit (36) connected via a nozzle (43) to the flow pipe. A blocking non-return valve (66) is arranged between the pressure balance and the consumer.</p> |
