Abstract

Válvula oleodinámica, en particular para un empujador hidráulico del tipo que comprende: los dos cubiletes deslizables uno dentro de otro, de los cuales el externo coopera con la superficie de la leva del árbol de levas por medio de un pequeño disco de registración mientras el interno se apoya sobre el extremo del vástago de la válvula; una cámara de expansión, definida entre las paredes frontales, encaradas, de los dos cubiletes y conectada con el circuito de lubricación del motor mediante un conducto de alimentación gobernado por dicha válvula, que se caracteriza por estar constituida por un asiento cónico, practicado en un orificio pasante en la pared frontal del cubilete interno, que comunica la cámara de expansión con la parte inferior del cubilete dicho conducto de alimentación; y un elemento en forma de hongo cuya cabeza el asiento cónico y cuyo tallo esta inserto en el espacio pasante que le sirve de guía.
