The invention relates to a hydraulic tank () for storing a hydraulic liquid, comprising a one-piece tank housing () which forms a plastic hollow body and is manufactured by a rotational moulding process, wherein the tank housing () comprises at least one connection opening () at which is arranged a connection element () that is releasably connectable to a hydraulic conduit. In order to enable the hydraulic tank to be more cost-effective to produce, the connection element () comprises a plastic body which is manufactured by an injection moulding process and is welded together with the tank housing (). Furthermore, a method for manufacturing a hydraulic tank () is proposed.

The invention relates to a filter device for filtering a liquid, in particular, a hydraulic oil, comprising a filter housing having a least one inlet for liquid to be filtered and at least one outlet for filtered liquid, a filter element positioned in the flow path of the liquid between the inlet and the outlet, and a sealing device having a sealing element and a first sealing surface, the sealing element in a sealing position being positioned in a sealing manner on the first sealing surface. In order to further develop the filter device in such a way that the sealing element also lies reliably on the first sealing surface under alternating pressure loads, it is proposed, in accordance with the invention, that the filter device comprise a locking device, and the sealing element be adapted to be locked in its sealing position at least in the axial direction relative to the first sealing surface by means of the locking device. A filter element for the filter device is also proposed.
