Description
間に半径方向シールを形成するために、結合部の各端部の近くの溝内に位置付けられた圧力エネルギー付与型エラストマーシールである。
するように構成され、その逆も然りであり、そこでは該シールリングは組み入れの時及びその後の何れに於いてもハウジングと共働して動作する。
1つの側面では溝13は、リング6の内面のより容易な圧搾を可能にすることに必要な半径方向変形を提供する空白部として作用し、
もう1つの側面ではリブ11,12が負荷集中をもたらし、これによりシール用の接触を増やし、二つの独立したシール用のバリヤとして作用する、ことをもたらす。
α>βで、かつ
γ>δ
が充たされる様な大きさを有する様に選ばれる。
