    摘要： The subject of the present invention is a ring seal preventing the seal from sliding and/or tilting when tightened.For this purpose, the invention proposes a seal (10) having an axis of revolution (R) and a median transverse axis (T), and comprising, in cross section, a general D shape defined by a wall (11) forming the back of the D, a wall (12) forming the belly of the D, and two side walls (13).The seal has a height (H) and a thickness (E), the ratio (E/H) of the thickness (E) over the height (H) being between 0.7 and 0.85, preferably 0.8.The back wall (11) comprises, in the uncompressed state, a concave face defining a hollow (11a) between two crowns (14), the hollow having a height (h) of between 50% and 60% of the height (H) of the seal, and a depth (p) of between 4% and 8% of the thickness (E) of the seal.

    摘要翻译： 本发明的主题是防止当紧固时密封件滑动和/或倾斜的环形密封件。 为此，本发明提出了具有旋转轴线（R）和中间横轴（T）的密封件（10），并且在横截面中包括由形成背部的壁（11）限定的一般D形状 的D，形成D的腹部的壁（12）和两个侧壁（13）。 密封件具有高度（H）和厚度（E），厚度（E）的高度（H）之比（E / H）在0.7和0.85之间，优选为0.8。 后壁（11）在未压缩状态下包括在两个冠部（14）之间限定中空部分（11a）的凹面，所述中空部分具有高度（H）的50％至60％之间的高度（h） 和密封件的厚度（E）的4％至8％之间的深度（p）。

    摘要： An annular gasket intended to provide a tight assembly between a first and second pipe after crimping, including an axis of revolution, whereof a section parallel to said axis is a curve formed by a series of an odd number of circle segments Ci connected by apices Si forming a regular polygon, i varying from 1 to 2*n+1, n being a positive integer greater than or equal to 1, the apex Si being the center of the circle passing through the apices Si+n and Si+n+i modulo 2*n+1. Such a curve is said to have a constant width. The apices Si advantageously form a polygon.
