Abstract (en)
[origin: WO2016008539A1] The invention relates to a closure element (1) for tightly closing a bore (2), the closure body (3) of which closure element can be pressed into the bore (2) with an oversize. In order to avoid damage to the bore, the closure body (3) is designed as a hollow body. In this way, the closure body can deform slightly as the closure body is pressed into the bore (2) and can thereby reduce the radial pressure on the wall (4) of the borehole. At the same time, the weight of the closure element is reduced. The closure element is preferably a hollow sphere having uniform wall thickness.
