1. A sealing device (100) for sealing off the intermediate space between a housing (200) and a shaft (310) which is rotatably mounted in the housing, having:
a first plate-shaped body (110) with a front side, a rear side and a first opening (120), which extends from the front side to the rear side and is suitable for the leadthrough of the shaft (310);
a line (130) running in the body (110), which is suitable for conducting a liquid or gaseous medium;
first sealing means (140);
wherein
the first body (110) is suitable to be fastened sealingly to the housing (200), such that the shaft (310) which is rotatably mounted in the housing (200) is directed through the first opening (120);
the line (130) has a multiplicity of outlets (138) which are connected to an inlet (132) via at least one diversion (134) and/or at least one divergence (136), and which lead radially symmetrically into the first opening (120);
the first opening (120) is suitable for the introduction of first sealing means (140) such that the first sealing means (140) seal off an intermediate space between the shaft (310) and the first body (110), without blocking the outlets (138) of the line (130); and
the first body (110) is formed in one piece; and
the first sealing means (140) are arranged with respect to the outlets (138) of the line (130) on the side at which the first body (110) is connected to the housing (200).
