Abstract

Patente de Invenção: <B>"DISPOSITIVO TENSOR DE MEIOS DE TRAçãO AMORTECIDO VISCOSAMENTE"<D>. Em um dispositivo tensor de meios de tração amortecido viscosamente, agente de amortecimento que se encontra em um espaço de amortecimento penetra em pelo menos um espaço de apoio. Este agente de amortecimento é supersolicitado por alto cisalhamento e destruído. O novo dispositivo tensor de meios de tração deve garantir um amortecimento substancialmente inalterado, mesmo após longa vida de serviço. Para isto está previsto que o espaço de apoio (16, 16', 16'') e o espaço de amortecimento (11, 11') estão separados um do outro de modo fluido. Assim evita-se a destruição do agente de amortecimento no espaço de apoio.Invention Patent: <B> "TENSIONING DEVICE FOR VISCOSALLY DAMAGED TRACTION MEDIA" <D>. In a viscous-dampened tensile device, the damping agent that is in a damping space penetrates at least one support space. This damping agent is over-ordered by high shear and destroyed. The new tensioning device must provide substantially unchanged damping, even after a long service life. For this purpose, it is provided that the support space (16, 16 ', 16' ') and the damping space (11, 11') are fluidly separated from each other. This avoids the destruction of the damping agent in the support space.
