  • Patent number: 4370952
    Abstract: A reciprocable piston internal combustion engine having an engine frame with at least one cylinder bushing inserted therein which bushing with the engine frame forms a cooling water receiving chamber or jacket surrounding the cylinder bushing. One end, with an upright cylinder the upper end, of the bushing rests by means of an axial and/or radial collar on the engine frame. The cylinder bushing has operatively associated therewith a heat jacket having a wall portion thereof in contact with cooling water in the interior of the cooling water receiving chamber. The heat jacket which may be in the form of a flat annular tube or pipe extends from the region of the cooling water receiving chamber to at least near, preferably into the collar. The interior of the heat jacket is advantageously so designed, e.g. has a capillary design, that the liquid heat carrier in the heat jacket will also be able to flow against the force of gravity in the longitudinal direction of the cylinder bushing.
