Compressor sealing element arrangement near stator for controlling gaseous fluid flow there through

An apparatus for compressing a gaseous fluid, comprising:

• a stator and a rotor which are arranged in such a way as to extend along a common longitudinal axis within a housing such that the stator encloses the rotor in a radial direction, and in that a space is formed between an inner side of a wall of the housing and an outer side of a wall of the stator, wherein the housing is formed from a first housing element and a second housing element, which are each arranged with mutually aligned contact surfaces closing the housing and resting against one another, wherein a sealing element is arranged between the contact surfaces, wherein the sealing element has a shape of an annular disc with a constant width, wherein the sealing element further includes a circumferentially extending form and at least one first sealing area, wherein the form corresponds in a circumferential direction to a contour of the contact surfaces and the at least one first sealing area partially closes the space between the inner side of the wall of the housing and the outer side of the wall of the stator, and wherein an outer diameter of the sealing element substantially corresponds to an outer diameter of the contact surfaces and an inner diameter of the sealing element substantially corresponds to a diameter of the outer side of the wall of the stator such that the sealing element abuts against the outer side of the wall of the stator.
