Abstract

La invencion se refiere a una válvula secuencial para utilizar en una planta hidráulica, dicha válvula secuencial tiene una válvula deslizable controlada por presion (5) con un resorte de retorno y en una posicion inicial define una primera cavidad (10), dicha cavidad está conectada con un tanque y con la planta hidráulica, y en una segunda posicion, bajo presion, cierra la conexion con el tanque. La cavidad está conectada con una segunda cavidad (18) por medio de un canal (15, 16, 17) en la válvula de deslizamiento, y la segunda cavidad está adaptada para conectarse con una bomba por medio de un regulador (20) y está posicionada sobre el mismo lado de la válvula deslizable como resorte (7). La válvula secuencial tiene una tercera cavidad (19), la cual está adaptada para conectarse con la bomba y está ubicada sobre el lado opuesto de la válvula de deslizamiento desde el resorte, y la segunda y la tercera cavidad están conectadas entre sí por medio de un regulador fijo con un canal de flujo corto. La invencion también se refiere a un tractor de fondo de pozo con la válvula secuencial.
