The cooling duct has a connection supplying the cooling liquid to the cooling duct and for discharging. Mating connections are connected to the connections of the cooling duct. The connections and the mating connections have sealing surfaces which face each other. The interior of the housing and the cooling duct is sealed via sealing devices each have two sealing rings spaced apart from each other. First sealing rings seal the cooling duct and the other sealing rings seal the housing. Annular grooves as outflow ducts in the housing lead off and open out on the outside of the housing and are introduced into the sealing surfaces in the region between the sealing rings.
