Abstract

Un motor de ciclo dividido incluye un cigüenal rotante alrededor de un eje de cigüenal. Un piston de compresion es recibido en forma deslizable dentro de un cilindro de compresion y conectado operativamente al cigüenal de manera que el piston de compresion se mueve en forma alternativa a lo largo de carreras de admision y compresion durante una misma rotacion del cigüenal. Un piston de expansion es recibido en forma deslizable dentro de un cilindro de expansion y conectado operativamente al cigüenal de manera que el piston de expansion se mueve en forma alternativa a lo largo de carreras de expansion y de escape durante una misma rotacion del cigüenal. Una lumbrera de transferencia interconecta los cilindros de expansion y de compresion. La lumbrera de transferencia incluye válvulas de compresion de transferencia (XovrC) y válvulas de expansion de transferencia (XovrE) que definen una cámara de presion entre sí. Por lo menos una de las válvulas XovrC y XovrE es una válvula con equilibrio de presiones. Un equilibrador de presiones de fluido desvía la válvula para equilibrar las presiones de fluido que actuan contra la válvula tanto en la direccion de apertura como en la direccion de cierre, reduciendo las fuerzas necesarias para actuar la válvula.
