An electric machine for a vehicle, in particular for a utility vehicle, includes a rotor mounted rotatably on a shaft and a stator surrounding the rotor, at least one device of the electric machine located in at least one pressure chamber which is subjected at least intermittently to an overpressure which is elevated with respect to the ambient pressure. The over pressure in at least one pressure chamber protects against ingress of water.

A valve cover of a internal combustion engine is fixed on the cylinder head by a plurality of screwed joints, preferably with a circumferential gasket inserted in between. At least some of the screwed joints are provided and/or coupled in such a way with a resiliently and/or elastically flexible element () on a cold side () of the cylinder head (), which faces away from the at least one exhaust port in the cylinder head () and hence faces a cold side of the engine, that the valve cover () lifts off from the cylinder head () in a defined area of the cover only in the area of said cold side () when there is a defined excess pressure in the crankcase.
