Abstract
Un sistema hidromecánico se describe para activar una válvula de apertura hacia afuera de un motor, tal como una válvula de pasaje de cruce de un motor de ciclo dividido. Una modalidad desarrollada incluye un cuerpo que tiene un cilindro de émbolo en comunicación fluida hidráulica con un cilindro de válvula. Un émbolo en el cilindro de émbolo es recíproco para desplazar el fluido hidráulico hacia el cilindro de válvula, la válvula del motor está abierta mediante el fluido hidráulico desplazado a través del émbolo hacia el cilindro de válvula y actúa contra el pistón de la válvula. Un muelle de válvula, de preferencia un muelle neumático regresa a la válvula del motor para engancharse a un asiento de válvula orientado hacia afuera para cerrar un paso de gas del motor. También se pueden incluir las características de las válvulas de control y un acumulador de reutilización de energía, junto con el control de asiento de válvula y el freno de elevación.
