Abstract

For a device for the reinforcement of the crankcase of a reciprocating piston engine, especially an internal combustion engine, with struts (11) connecting the crankcase walls on both sides of a crankshaft drive, it is proposed, in order to increase the bending and torsional rigidity of the device, that the struts be firmly connected to one another by way of baffle or guide surfaces (14, 14'; 15, 15'; 16, 16'; 17, 18, 19) arranged slanting in relation to a lubricating oil roller rotating with the crankshaft drive. <IMAGE>
