<p>A rubber elastic packing ring (13) is arranged between two concentric machine parts (11, 12) moved towards each other. The packing ring (13) has a surface (22) that on the one hand ends in a dynamic sealing edge (21) and on the other hand extends to the low pressure side N. In addition, an outer circumferential surface (25) of the packing ring (13) is inclined towards the bottom (18) of the groove in the non-compressed state of the packing ring (13). Imaginary planes (35, 36) extend through the ring-shaped conical surfaces (22, 25). The imaginary planes (35, 36) are also conical ring-shaped surfaces that form an intersection line (37). The intersection line (37) is always located between one plane (34) (ring-shaped surface) and the circumferential surface (15) of the second machine part (12).</p> |
