Abstract:
1. A closing element for sealing a hole of a component subjected to internal pressure, comprising: a main body insertable into the hole substantially without play, said main body including a side wall and a closing bottom portion, and a spreading element pressable in an axial direction into said main body, said main body and said spreading element being configured to cause said side wall of said main body to be pressed radially outward when said spreading element is axially pressed into said main body and against said bottom portion, whereby the radially outward pressing of said side wall of said main body upon axial pressing of said spreading element against said bottom portion causes, when the closing element is inserted in the hole, said side wall to press against a wall defining the hole to thereby close the hole, a face of said spreading element that is pressed at at least one edge into contact with said bottom portion having an inner edge and an outer edge, said bottom portion being configured such that contact between at least one of said inner and outer edges and said bottom portion upon axially pressing of said spreading element into said main body causes said side wall of said main body to be pressed radially outward.
