  • Patent number: 8608957
    Abstract: An oil container has a container housing receiving an oil filter and fittings for an oil inlet, an oil outlet, for filling the oil container, and for an opening that can be closed by a cover for temporarily removing or replacing the oil filter, as well as, an air outlet opening. The container housing is divided into at least two chambers by a partition, each chamber including an oil filter. Each chamber has an oil inlet fitting, an oil outlet fitting, and an opening that can be closed by a cover for filling with oil and/or for removing the oil filter. The partition includes an oil overflow opening located above a minimum oil filling level height relative to a rest state determined for the individual oil circuits. A leak occurring in one of the oil circuits does then not affect the operational reliability of the other oil circuit(s).
