摘要： In a metallic gasket having a metallic sheet made with a recess surrounding around a diverse type of hole, in which an elastic sealing member is installed, a relation between the recess and the elastic sealing member in their cross sections and also configurations is so specified as to use the elastic sealing member within a range of elastic limit inherent in the elastic sealing member, thereby improving the sealing performance of the metallic gasket. The elastic sealing member installed in the recess formed around the hole such as combustion hole and so on is composed of a top extending above a major side of the metallic sheet, and a bottom having a cross section reaching widthwise opposing side surfaces of the recess. The elastic sealing member is made not more than the recess in their cross section perpendicular to the major side of the metallic sheet. Thus, the elastic sealing member, when the metallic gasket is squeezed, may serve its useful function within the range of inherent elastic limit. This helps ensure the properly tight and enduring sealing condition, thereby keeping the gasket against premature degradation and any collapse.
摘要翻译：在具有金属片的金属制垫片中，该金属片具有围绕各种类型的孔围绕的凹部，其中安装有弹性密封构件，凹部和弹性密封构件之间的横截面和构造的关系如在弹性密封构件固有的弹性极限范围内使用弹性密封构件，从而提高金属衬垫的密封性能。安装在诸如燃烧孔等的孔周围形成的凹部中的弹性密封构件由在金属片的主侧上方延伸的顶部以及具有横截面的宽度方向相对的侧面的底部构成。弹性密封构件在垂直于金属片的主侧的横截面中不大于凹部。因此，当金属垫圈被挤压时，弹性密封件可以在固有弹性极限的范围内起作用。这有助于确保适当紧密且持久的密封条件，从而保持垫圈免于过早降解和任何塌陷。
