Increasing resource of active type sealing connections by modification of mounting places

A modified design of sealing compound is presented. It allows to secure the significant resource increase of fixed sealing compounds on the basis of round section seals. Increased resource of the sealing compound is achieved so that additional annual grooves with a cross-section of an ellipse form with large segments of the axis are carried out. They are made symmetrically to the walls of the rectangular groove on the bottom of rectangular section groove and in the principal detail. It reduces relaxation speed of the contact stresses in the seal. High exploitational proofs are theoretically and experimentally confirmed by numerical simulation and by bench-top tests.
