CLOSURE ELEMENT FOR BORES SUBJECTED TO INTERNAL PRESSURE |
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. |
