Abstract

Un ensamblaje de control de bomba incluye un ensamblaje de bomba de fluidos (12) teniendo una bomba de fluidos (20) y una válvula de detección de carga. La bomba de fluidos incluye una entrada de fluidos (24) y una salida de fluidos (26). La bomba de fluidos incluye un mecanismo de desplazamiento variable (36). La válvula de detección de carga (42) se adapta para ajustar la posición del mecanismo de desplazamiento variable. La válvula de detección de carga incluye un primer extremo (46) y un segundo extremo dispuesto de manera opuesta (48). Un accionador (60) está en comunicación de fluidos con el ensamblaje de bomba de fluidos. Un sensor de posición (100) monitoriza la posición del accionador. Una válvula de rampa (110) proporciona comunicación de fluidos selectiva entre la salida de fluidos de la bomba de fluidos y el primer extremo de la válvula de detección de carga. Una unidad de control electrónico está en comunicación eléctrica con el sensor de posición y la válvula de rampa. La unidad de control electrónico transmite una corriente de salida a la válvula de rampa en respuesta a la posición del accionador.
