摘要： A seal assembly that seals a gap formed by a groove comprises a seal body, a biasing element, and a connection that connects the seal body to the biasing element to form the seal assembly. The seal assembly further comprises a concave-shaped center section and convex-shaped contact portions at each end of the seal body. The biasing element is formed from an elastic material and comprises a convex-shaped center section and concave-shaped biasing zones that are opposed to the convex-shaped contact portions. The biasing element is adapted to be compressed to change a width of the seal assembly from a first width to a second width that is smaller than the first width. In the compressed state, the seal assembly can be disposed in the groove. After release of the compressing force, the seal assembly expands. The contact portions will move toward a surface of the groove and the biasing zones will move into contact with another surface of the groove. The biasing zones will bias the contact portions of the seal body against the surface of the groove.

摘要翻译： 密封由凹槽形成的间隙的密封组件包括密封体，偏置元件和将密封体连接到偏置元件以形成密封组件的连接。 密封组件还包括在密封体的每个端部处的凹形中心部分和凸形接触部分。 偏置元件由弹性材料形成，并且包括凸形中心部分和与凸形接触部分相对的凹形偏压区域。 偏置元件适于被压缩以将密封组件的宽度从第一宽度改变为小于第一宽度的第二宽度。 在压缩状态下，密封组件可以设置在凹槽中。 释放压缩力后，密封组件膨胀。 接触部分将朝向槽的表面移动，并且偏置区域将移动成与槽的另一个表面接触。 偏置区域将偏压密封体的接触部分抵靠凹槽的表面。
