閉鎖要素
Document Type and Number:
Japanese Patent JP5836386
Kind Code:
B2
Abstract:
Closing element for sealing holes subjected to internal pressure includes a hollow cylindrical main body insertable into the hole substantially without play, and a hat-like spreading element pressable into the main body. The spreading element applies radial pressure to the inner wall of the main body in the installed state, wherein the main body is spread and pressed against the wall of the hole. The main body has a closing bottom having a circumferential radial ring surface and a slightly conical cone surface connected thereto. During operation, the closing bottom is pressed against the end face of the spreading element by the internal pressure and is bent over inner and outer edges 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, and self-reinforcement of the press-out force required to remove the closure.
