Abstract

La invención se relaciona con una válvula de secuencia para uso en una planta hidráulica, la válvula de secuencia tiene una válvula deslizante controlada por presión (5) con un resorte de regreso y en una posición inicial define una primera cavidad (10), cuya cavidad está conectada con un tanque y la planta hidráulica, y en una segunda posición presurizada cierra la conexión con el tanque. La cavidad está conectada con una segunda cavidad (18) a través de un canal (15), (16), (17) en la válvula deslizante, y la segunda cavidad está adaptada para conectarse con una bomba a través de un regulador (20) y se posiciona en el mismo lado de la válvula deslizante que el resorte (7). La válvula de secuencia tiene una tercera cavidad (19) la cual está adaptada para conectarse con la bomba y está posicionada en el lado opuesto de la válvula deslizante desde el resorte, y la segunda y tercera cavidades están conectadas entre sí a través de un regulador fijo con un canal de flujo corto. La invención también se relaciona con el tractor para el fondo del pozo con la válvula de secuencia.
