Abstract: An apparatus for degreasing solid and/or mass-produced parts, such as small metallic parts comprises a drum with a perforated drum wall rotatable and drivable around a vertical axis. A charge opening is furnished at the top and a discharge opening furnished at the bottom. The discharge opening is closable by an axially movable floor closure. A stationery outer ring channel surrounds the drum and exhibits at the bottom an outer ring trough with discharge port. An inner ring channel is disposed between the outer ring channel and the drum and axially adjustable by way of an adjustment member and including an inner ring trough at the bottom. Feed lines for treatment agent lead into the drum. The inner ring channel is formed adjustable from the starting position, releasing the drum perforations, into a center position covering the drum perforations on the outside, and into a sealing position for sealing the drum.

Abstract: The invention concerns a device for the oil treatment of sintered parts consisting of a drum (11, 111) which is mounted so that it can rotate about a vertical axis and which can be driven. It has a drum mantle (11′, 111′) and loading and unloading devices so that it can be loaded and unloaded axially, a floor that tightly closes the opening in the floor (19, 119) against the-drum mantle (11′, 111′), connections (28, 29, 30, 31/128, 129, 130, 131) leading into the drum (11, 111) for liquid and gaseous treatment media for carrying out the treatment phases, and outlets (35, 135) for letting treatment fluids out of the drum (11, 111). The task of the invention is to create a device that not only mechanizes the treatment process but also can be repeated many times, always in the same way.
