1. A hydraulic arrangement configured for actuating hydraulic consumers and for one or both of either cooling a heat source or lubricating a component part within a drivetrain of a motor vehicle, the hydraulic arrangement comprising:
a reversing pump configured for conveying hydraulic medium in opposite conveying directions, the reversing pump having a first pump connection and a second pump connection,
an active valve device configured as a 6/2-way valve, the active valve device having:
a first actuating connection for a first hydraulic actuator,
a second actuating connection and a third actuating connection for a second hydraulic actuator,
a fourth actuating connection for cooling at least one of the heat source or lubricating the component part, wherein:
the first pump connection of the reversing pump is hydraulically connected to a first valve inlet of the active valve device and the second pump connection of the reversing pump is hydraulically connected to a second valve inlet of the active valve device, and
in a first shifting position of the active valve device:
the first valve inlet is hydraulically coupled to the second actuating connection and the second valve inlet is hydraulically coupled to the third actuating connection when the first actuating connection and the fourth actuating connection are each in a blocking position, and
in a second shifting position of the active valve device;
the first valve inlet is hydraulically coupled to the first actuating connection and the second valve inlet is hydraulically coupled to the fourth actuating connection when the second actuating connection and the third actuating connection are each in a blocking position.
