Abstract

An apparatus comprising a stator and a rotor which are arranged inside a housing extending along a common longitudinal axis, wherein the stator encloses the rotor in a radial direction. A space is formed between an inside of a wall of the housing and an outside of a wall of the stator. The housing has a first housing element and a second housing element that are arranged with their contact surfaces aligned with each other thus sealing the housing. Thereby, a sealing element is arranged between the contact surfaces of the housing elements. The sealing element has the shape of an annular disc with a circumferential form and at least one sealing area. In the circumferential direction, the form corresponds to a contour of the contact surfaces. The sealing area is designed to at least partially enclose the space.
