"Improvements in semi integrated devedau00e7u00e3o for girabrequim axis in the retainer of the system.PTFE sealing element that composes the retainer and in the process of obtaining PTFE sealing element.This summary indicates sea invention patent for improvements in semi integrated sealing, in the retainer that is part of the same.The sealing element of PTFE of the retainer and in the process of obtaining PTFE sealing element; said system being understood, substancialmento: a permanent structural element (1),Assembly of the engine block and sealing element which incorporates EST [for the surface (10) and the sealing element of the corner (20).These elastomeric and incorporated in the structural component / assembly (1) for vulcanization; and the retainer radial seal (30) is formed by sealing lip main polytetrafluoroethylene.Fe (40) with hydrodynamic seal (41); the sealing lip against the entry of powder rubber or felt type material (50), both sealing against the shaft girabrequim; and housing (60).All incorporated into each other by vulcanization or vulcanization and gluing or pressing, forming a set ring originalmenteo isolated from the structural element / assembly (1) and that.The level of the factory.This is mounted and fixed by interference; said sealing lip is composed of a main PTFE PTFE sealing element (40) having hydrodynamic seal (41) moulded under heat and PR.Progress in form, preferably of helical groove with at least two sections interrupted (stopers) (42) for static sealing.
