Abstract
Retén frontal, especialmente para el estancamiento en bombas, del tipo que comprenden un anillo deslizante desplazable, una pieza moldeada elástica que produce estancamiento estático del anillo deslizante con respecto al árbol, y un muelle de compresión que circunda concéntricamente al árbol para apretar axialmente el anillo deslizante contra el anillo contraria mientras que el muelle de compresión está unido con el árbol por fricción con al menos una de sus espiras en el extremo contrario al del anillo deslizante, caracterizado porque un extremo axial del muelle de compresión (5) circunda con tensión radial, al menos con una espira (7), al anillo deslizante (3), porque el muelle de compresión (5) presiona axialmente, al menos con una espira de muelle (9), sobre la superficie frontal libre del anillo deslizante"'' (3), a través de la pieza moldeada (4) elástica, y porque el muelle de compresión (5) descansa, al menos con otra espira (8), en la periferia exterior de la pieza moldeada (4) elástica, en la zona de estancamiento estático del anillo deslizante (3) con respecto al árbol (2), y presiona a ésta radialmente contra el árbol (2).
