Abstract

Dispositivo para el control de entrada y salida de aceite en cilindros hidráulicos, especialmente cilíndricos de prensa, caracterizado por el hecho de comprender una caja cilíndrica, que presenta un orificio coaxial comunicante con el cilindro del martinete de la prensa; una pluralidad de lumbreras formadas en la caja y que ponen en comunicación el orificio con el depósito de aceite; un pistón guiado deslizante dentro de la caja y que la divide en una cámara superior, conectable a través de medios valvulares con la llegada de aceite a presión y una cámara inferior, comunicante con el depósito a través de aberturas de la caja; un resorte de retorno del pistón, alojado en la cámara inferior, y un vástago unido coaxialmente al pistón y guiado herméticamente en el orificio, siendo dicho vástago movible entre una posición de intercepción de las lumbreras y una posición de apertura de las mismas.
