摘要： A closure element serves for closing off bores which are subjected to internal pressure, preferably bores in engine or valve blocks or tanks. Said closure element has a sleeve-shaped main body which can be inserted into the bore and the outer circumference of which, in the installed state, bears sealingly against the inner surface (2) of the bore (3). Provided are the main body and an expanding body (4) which is connected to said main body by a bent-over transition region (8). The closure element is firstly inserted into the bore (3) and subsequently pressed into the latter by the application of pressure to the expanding body (4). As the closure element is pressed into the bore (3), the expanding body (4) is pushed into the main body (1) by deformation, so as to push the main body (1) in the radial direction against the inner surface (2) of the bore (3). In this way, said closure element can withstand even relatively high internal pressures and can be produced in a simple manner.

摘要： The invention relates to a closing element for sealing holes subjected to internal pressure, comprising a hollow cylindrical main body (3) that can be inserted into the hole substantially without play, and a hat-like spreading element (8) that can be pressed into the main body, wherein said spreading element applies radial pressure to the inner wall of the main body (3) in the installed state, wherein the main body is spread and pressed against the wall of the hole to be closed. The main body (3) has a closing bottom (5), which has a circumferential radial ring surface (6) and a slightly conical cone surface (7) connected thereto, wherein during operation the closing bottom is pressed against the end face (12) of the spreading element (8) by the internal pressure and is bent over the inner and outer edge of the end face and deformed so as to expand radially. This results in strengthened anchoring of the closure in the material of the component, wherein at the same time a self-reinforcement of the press-out force required to remove the closure is caused.
