ABSTRACT:
Known disk oil coolers, when they are to be used without an oil filter, are provided with a separate housing cover which, by means of a sealing device, is disposed on a ring surface of the housing and is held on the housing by way of a hollow screw. These constructions require a large amount of space. It is disclosed to provide the hollow screw, on the side of the driving surfaces for a screwing tool directed toward the housing, with an end disk which is provided with a sealing surface resting against an annular wall of the housing. On the side of the end disk facing the housing, an opening is provided which leads into the interior of the hollow screw. This hollow screw may be used instead of the hollow screw to be provided for the use with the filter. Elaborate modifications or other housings are not required.
