Abstract

A component housing in a motor-vehicle drive train is sealed by pressurization of the housing interior. The component is a hybrid module (1) comprising at least one electric machine provided between the combustion engine (VM) and the gearing (G) of the motor-vehicle drive train. The pressurization is achieved by a rotating component (R, RA, M, F) of the hybrid module. The rotating component is designed in a manner similar to an impeller of a centrifugal pump. Therefore, rotation of the component builds up a positive pressure (P) on the radially outer region of the rotating component in the region of the housing (GE) in the interior of the hybrid module.
