Abstract: A hydraulic control block has at least two pressure supply circuits, which each include one or more hydraulic consumer ports, and at least two hydraulic pump ports. A valve arrangement is provided, by way of which each of the at least two pump ports can selectively connect with at least one of the pressure supply circuits selectively individually or in combination with at least one of the remaining pump ports. At least one direct connection of a consumer port is provided per pump port.

Abstract: A hydraulic system has at least one consumer and at least one hydraulic pump. A pressure limiting valve for limiting the maximum system pressure is connected with the at least one hydraulic pump, and the pressure limiting valve is pilot-controlled for switching a bypass. The invention also concerns a pressure limiting valve for limiting the system pressure inside such a hydraulic system.

Abstract: This present disclosure relates to a device for recovering hydraulic energy in an implement with a mooring pump for operation as pump or as motor, with a high-pressure accumulator and with a throttle differential circuit for connecting the bottom side of a working cylinder with the rod side of the working cylinder of the implement, and to a corresponding implement.
