Abstract (en)

[origin: EP0717201A2] The overflow valve for each consumer circuit is enclosed by a direction connection (29,26) which each include a shut-off device (12,19) controlled by the pressures of the two consumer circuits (10,21). When there is a higher pressure in the consumer circuits not allocated to same than in the consumer circuit (10,21) which is allocated to same the shut-off device is switched into the blocking position. At least one of the direct connections has a secondary non-return valve (30,27) which is permeable in the direction of the associated consumer circuit. At least one of the shut-off devices only switches into the shut-off position when there is a predetermined pressure difference.
