Alternatively, or in addition thereto, a partition for degassing the oil in the tank is provided. Furthermore, alternatively or in addition thereto, at least one partition for extending a flow path of the oil is provided. It is also conceivable, alternatively or in addition thereto, to arrange a cooling device in the annular space. ## Claims ### Claim 1 A tank for a compact assembly, comprising: an inner wall; an outer wall, which encompasses the inner wall and which, together with the inner wall, defines an annular space; a bottom wall that closes a bottom of the annular space; an inlet connection for an oil opening out into the annular space; an outlet connection for an oil opening into the annular space; and at least one of: a dividing wall configured to separate the inlet and outlet connections; a first partition for degassing the oil is arranged in the annular space, the first partition having a partition opening configured for oil flow; a second partition extending from the outer wall or from the inner wall, or a plurality of second partitions, each of which extends from the outer wall or from the inner wall into the annular space and configured to at least one of extend a flow path of the oil between the inlet and outlet connections and to reinforce the tank; and at least one cooling device arranged in the annular space and through which the oil flows. ### Claim 2 (depends on 1) The tank according to claim 1, wherein the first partition for degassing has a lower edge which, together with the bottom wall, the outer wall, and the inner wall, defines a lower partition opening through which the oil flows. ### Claim 3 (depends on 1) The tank according to claim 1, wherein at least two second partitions are provided to extend the flow path, the at least two partitions extending alternately from the outer wall and the inner wall. ### Claim 4 (depends on 1) The tank according to claim 1, wherein the at least one cooling device has a plurality of blades. ### Claim 5 (depends on 4) The tank according to claim 4, further comprising: a labyrinth seal encompassing the plurality of blades on at least one of a radially inwardly side, a radially outwardly side, a bottom side, and a top side. ### Claim 6 (depends on 4) The tank according to claim 4, wherein the blades are operatively connected to at least one heat pipe. ### Claim 7 (depends on 6) The tank according to claim 6, wherein the at least one heat pipe is operatively connected to a heat sink, which is formed by an end cover of the tank. ### Claim 8 (depends on 5) The tank according to claim 5, wherein the labyrinth seal is formed by at least one of a radially inner web and a radially outer web. ### Claim 9 (depends on 1) The tank according to claim 1, wherein a discharge opening of the outlet connection is oriented approximately in at least one of a flow direction and a direction away from the dividing wall. ### Claim 10 An electrohydraulic compact assembly, comprising: a tank comprising: an inner wall; an outer wall, which encompasses the inner wall and which, together with the inner wall, defines an annular space; a bottom wall that closes a bottom of the annular space; an inlet connection for an oil opening out into the annular space; an outlet connection for an oil opening into the annular space; and at least one of: a dividing wall configured to separate the inlet and outlet connections; a first partition for degassing the oil is arranged in the annular space, the first partition having a partition opening configured for oil flow; a second partition extending from the outer wall or from the inner wall, or a plurality of second partitions, each of which extends from the outer wall or from the inner wall into the annular space and configured to at least one of extend a flow path of the oil between the inlet and outlet connections and to reinforce the tank; and at least one cooling device arranged in the annular space and through which the oil flows; a hydraulic load; and an electric machine configured to drive the load, wherein the electrohydraulic compact assembly is configured such that the hydraulic load sucks oil out of the outlet connection and conveys the oil into the inlet connection by the load.
