摘要： A soil processing roller includes an elongated roller shell that rotates about a roller axis of rotation and a first fluid chamber in a roller interior space delimited by the roller shell. In association with the first fluid chamber a first opening group is provided which includes a first filling opening, a first discharge opening and a first fill level control opening. A shielding element is arranged in an axial end region of the roller interior space which does not rotate about the roller axis of rotation during a soil processing operation. A first release recess is provided in the shielding element, and a second fluid chamber substantially separated from the first fluid chamber against fluid exchange is delimited by the roller shell. In association with the second fluid chamber a second opening group is provided which includes a second filling opening, a second discharge opening and a second fill level control opening.

摘要： A soil processing machine, in particular a soil compactor, includes at least one drive roller and an electrohydraulic drive system for driving at least one drive roller. The drive system has a traction hydraulic circuit having at least one hydraulic motor and at least one hydraulic pump. The circuit includes a first line region between a first connection fitting of the at least one hydraulic pump and a first connection fitting of each hydraulic motor to drive the at least one drive roller in a first rotatable direction and a second line region between a second connection fitting of the at least one hydraulic pump and a second connection fitting of each hydraulic motor to drive the at least one drive roller in a second, opposite rotatable direction. A valve assembly is provided with each line region for selectively interrupting and releasing a fluid flow connection between the at least one hydraulic pump and at least one hydraulic motor.
