Abstract
Un sistema hidráulico incluye una bomba hidráulica la cual proporciona fluido presurizado en una lumbrera de salida como una función de la presión en una lumbrera sensora de carga, un depósito hidráulico, y una línea sensora de presión de cara conectada a la lumbrera de percepción de carga. Una válvula de control de implemento operada por solenoide controla la comunicación de fluido a y desde una función hidráulica tal como un cilindro. Una válvula de control de suministro tiene una primera posición en la que el depósito se comunica con la lumbrera de percepción de carga y una segunda posición en donde la lumbrera de salida de bomba se comunica con la lumbrera de percepción de carga. Un resorte presiona el miembro de válvula a la primera posición, y un solenoide puede activarse para mover el miembro de válvula a su segunda posición, el solenoide es energizado cuando la válvula de control de implemento es activada de manera que la válvula de control de suministro comunica la presión de bomba a la lumbrera de percepción de carga y la bomba operará a una capacidad completa cuando la segunda función hidráulica es operada.
