Embodiment Construction
[0021] figure 1 The closure element 1' shown in is used to tightly close a hole 2' with a closure body 3' whose diameter is oversized relative to the diameter of the hole to be closed. By pressing the closure body 3' into the hole 2', the hole 2' is securely closed.
[0022] Such a closure element 1 is inserted into a housing with a hole 2 and a wall 4 , such as an engine housing of a motor vehicle, a hydraulic unit, a valve block or the like.
[0023] if possible from figure 2 As seen in , in the case of a conventional solid sphere 3', due to its excessive size, a high degree of radial pressure is exerted on the walls 4', 5' and also in the region of the hole into which the sphere is inserted, thereby causing the hole deformation or damage.
[0024] The closure element 1 according to the invention is characterized in that its also oversized closure body 3 is made in the form of a hollow body so that it can easily be elastically and / or plastically deformed. Thus, the rad...
