Abstract

본 발명의 목적은 열팽창계수가 낮은 개선된 밀봉장치를 제공하려는 것이다. 본 발명의 밀봉장치는 공간부(4)가 형성되어 있는 몸체(2)의 사용을 제공한다. 이러한 공간부는 몸체보다 열팽창계수가 낮은 재료로 전체적으로 또는 거의 채워지는데, 일부 실시예에서는, 저온에서 팽창하는 재료로 채원진다. 저온작동중에, 이 몸체는 상당히 수축하지만, 2개의 표면사이에 작용하는 압출력은 열팽창계수가 낮은 내부 충전물로 인해서 두드러질만큼 감소하지 않는다. 따라서, 저온작동시 본 발명의 밀봉장치의 파손의 위험은 거의 감소된다.It is an object of the present invention to provide an improved sealing device with a low coefficient of thermal expansion. The sealing device of the present invention provides for the use of the body 2 in which the space 4 is formed. These spaces are wholly or nearly filled with a material having a lower coefficient of thermal expansion than the body, in some embodiments, filled with a material that expands at low temperatures. During low temperature operation, the body shrinks considerably, but the extrusion force acting between the two surfaces does not significantly decrease due to the internal filling with a low coefficient of thermal expansion. Therefore, the risk of breakage of the sealing device of the present invention in low temperature operation is almost reduced.
