Abstract

La presente invención se refiere a una disposición de retardo por alivio de compresión de gas para un motor de combustión interna multi-cilíndrico de cuatro tiempos que tiene un cigüeñal y un árbol de levas accionado en sincronismo con el cigüeñal, pistones de motor conectados operativamente con el cigüeñal, medio de válvula de escape y medios de válvula de admisión para cada cilindro del motor, tubos de empuje primero y segundo accionados por el árbol de levas, medios de suministro de flúido hidráulico, y un primer pistón accionado hidráulicamente asociado operativamente con los medios de válvula de escape para producir la apertura de estos últimos, caracterizada por un segundo pistón accionado por el primer tubo de empuje y conectado hidráulicamente con el primer pistón y el suministro de flúido hidráulico para abrir los medios de válvula de escape durante una carrera ascendente del pistón del motor asociado con los medios de válvula de escape, correspondiente a su carrera de compresión durante la operación normal generando potencia del motor a fin de producir un primer evento de alivio de presión, primeros medios que responden al flúido hidráulico presurizado suministrado por los medios de suministro de flúido hidráulico, adaptados para inhabilitar la operación normal de los medios de válvula de escape, segundos medios que responden al flúido hidráulico presurizado suministrado por los medios de suministro de flúido hidráulico, adaptados para inhabilitar la operación normal de los medios de válvula de admisión, un tercer pistón asociado con los medios de válvula de admisión e interconectado hidráulicamente con los pisones primero y segundo para abrir los medios de válvula de admisión en un movimiento predeterminado, un cuarto pistón accionado por un segundo tubo de empuje e interconectado hidráulicamente con los pistones primero, segundo y tercero para accionar el primer pistón a fin de abrir los medios de válvula de escape durante una carrera ascendente del pistón asociado con los medios de válvula de escape correspondiente a su carrera de escape durante la operación normal del motor para producir un segundo evento de alivio de compresión y luego accionar el tercer pistón para abrir los medios de válvula de admisión con lo cual se produce un evento de alivio de compresión en cada cilindro durante cada vuelta del cigüeñal.
