The invention relates to an intermediate plate for mounting between housing parts of a fluid-operated control unit, in particular a gear unit, including a central unit that is constructed in the shape of a plate and, on either side of the central unit, a respective sealing system for sealing between the central unit and the housing part opposite the latter, this sealing system including sealing elements which are arranged on the respective side of the central unit and provide sealing around passages.
Intermediate plates of this kind are known from the prior art.
In these, the problem arises of achieving the best possible seal between the central unit and the respective housing part that also maintains leak-tightness in the event of any kind of deformation of the housing parts and the central unit, even in the event of the high fluid pressures that are conventionally present in the case of a gear unit.
