Abstract: A metal bead gasket (11) with a sealing region (12) having at least one bead (9), at least one bracing region (13) having at least one recess (21) for receiving a bracing means (5), in particular a screw, and at least one intermediate region (14) which connects the sealing region (12) to the bracing region (13). The intermediate region (14) is configured to be more deformationally unstable perpendicularly to the bracing direction (4) than the sealing region (12) and/or the bracing region (13).

Abstract: A liquid cooling system for an internal combustion engine charged by a turbosupercharger has forced circulation cooling of the engine and turbosupercharger. To cool the turbosupercharger after the internal combustion engine has been switched off the turbosupercharger inlet pipe contains a check valve and a return flow pipe to an expansion tank is split into branch pipes, a first pipe entering the expansion tank above the cooling liquid level and a second pipe entering the expansion tank below the cooling liquid level and having a check valve. Upon switching off the engine, the cooling liquid in the turbosupercharger is evaporated by residual heat and discharges the cooling liquid into the expansion tank in a cyclic, thrust-like process.
