Cooling apparatus for linear motor with improved sealing

An assembly, comprising:

• an electric linear motor including an active part;
• a cooling apparatus placed on the active part, said cooling apparatus comprising a carrier element configured for placement on the active part of the electric linear motor, a cooling element, a retaining element configured to mount the cooling element on the carrier element and having a first planar area on a side facing the active part of the electric linear motor and a second planar area on a side facing away from the active part of the electric linear motor, said retaining element having an opening sized to extend between the first and second planar areas for passage of a fastening element, each of the first and second planar areas having formed therein a cutout circulating around the opening, and a sealing element received in the cutout;
• a cover element configured for placement on the cooling apparatus;
• and
• a fastening element passing through the opening of the retaining element for fastening the cover element to the active part, so that the active part rests under pressure on the first planar area of the retaining element, and the cover element rests under pressure on the second planar area of the retaining element.
