Abstract
Un dispositivo de retén hidrodinámico, direccional, para aceite, que comprende una caja anular, y un elemento obturador a modo de arandela delgada que tiene una porción radialmente exterior soportada mediante dicha caja y una porción radialmente interior, generalmente cilíndrica destinada a aplicarse con un eje, teniendo la porción radialmente interior de dicho elemento obturador una pluralidad de hendiduras generalmente arqueadas en su superficie que se extienden en ángulo agudo con relación al eje geométrico central del eje y divergentes desde el lado piel aceite de dicho retén y que intersecan el borde radialmente interior de dicho elemento obturador para efectuar el bombeo hidrodinámica en conjunción con un eje giratorio.
