SEAL Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: end face seal is provided with a cover arranged in the zone of portion 17. Spring 10 bears on bottom 21 of cover 20. A force exerted by spring 10 is precisely directed along axle 22 due to the support abuts against bottom 21 of cover 20. The cover in turn is precisely oriented with respect to end face side 23 and radial side 24 of housing 2. This allows pressure-tightness both in the zone of contact of ring 11 with end face of hub 7 and in the zone of contact of collar 12 with radial side 24 and end face side 23 of housing 2. EFFECT: enhanced reliability. 2 cl, 2 dwg
