Abstract: 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.

Abstract: A roller tool for a soil processing roller includes a tool carrier to be fixed to an outer circumferential side of a carrier jacket and has a tethering area for fixedly tethering the tool carrier to an outer circumferential surface of the carrier jacket and an interchangeable holder clamping region, an interchangeable tool having an interchangeable tool shank elongated in the direction of a shank longitudinal axis, an interchangeable holder having an interchangeable holder opening elongated in the direction of an opening longitudinal axis for receiving the interchangeable tool shank of the interchangeable tool to be detachably fixed to the interchangeable holder and with an interchangeable holder counter-clamping region. The interchangeable holder counter-clamping region is brought into clamping interaction with the interchangeable holder clamping region for detachably fixing the interchangeable holder to the tool carrier.

Abstract: A compactor roller for a soil compactor comprises an oscillation mass assembly (34) including at least one oscillation shaft (36) rotatable about an oscillation-shaft axis of rotation eccentric to a compactor-roller axis of rotation, which oscillation mass assembly (34) includes at least one oscillation unbalance mass (66, 68), and a vibration mass assembly (84) including a vibration shaft (86) rotatable about a vibration shaft axis of rotation (Dv), which vibration mass assembly (84) includes at least one vibration unbalance mass (96), wherein at least one oscillation shaft (36, 38) and the vibration shaft (86) are carried in the compactor roller (10) such that they can be driven to rotate.

Abstract: A regenerative heat exchanger for the heat exchange of gaseous media with a substantially cylindrical heat storage body including a radial seal for use in a regenerative heat exchanger and a method for separating gaseous media in a regenerative heat exchanger. The heat storage body of the regenerative heat exchanger may include a plurality of radially extending sector walls which subdivide the heat storage body into sectors. At least two heat storage chambers which are arranged behind one another in the radial direction are provided within a sector, which heat storage chambers are arranged for the through-flow of gaseous media.

Abstract: The invention relates to a method for temperature-dependent setting of a sealing gap between an adjustable seal and a revolving rotor of a regenerative heat exchanger by means of at least one actuating apparatus which comprises at least one rod body which is thermally influenced in an alternating manner and whose temperature-dependent change in axial length is converted into an actuating movement for the seal. It is provided in accordance with the invention that this rod bod is arranged at least in sections in a chamber and a control medium flows through or about this chamber at least in part, which medium acts in a direct or indirect manner in a thermally alternating fashion on said rod body, with the temperature level of the control medium corresponding to a temperature level of a gas volume flow flowing through the rotor, so that a change in axial length of this rod body is produced depending on a temperature change of this gas volume flow and a respective actuating movement for the seal is brought about.

Abstract: A regenerative heat exchanger, including a rotor mounted so it is rotatable, which has at least one first gas volume flow to be heated and at least one second gas volume flow to be cooled flowing through it, as well as a method for operating the regenerative heat exchanger, is provided. The inflowing first gas volume flow enters the rotor at a first front side of the rotor and exits the rotor again at a second front side of the rotor at an outflowing first gas volume flow. To increase the heating performance, a leakage volume flow is captured at the first front side of the rotor and supplied to the inflowing first gas volume flow and/or a leakage volume flow is captured at the second front side of the rotor and supplied to the outflowing first gas volume flow.
