Abstract

VALVULA DE EXPULSION PARA MOTORES DE DOS TIEMPOS, PARA CONTROLAR LA CANTIDAD DE FLUIDO PURGADO DE UN CILINDRO DEL MOTOR, CON ANTERIORIDAD A LA COMBUSTION DE LA MEZCLA AIRE/COMBUSTIBLE DENTRO DEL CILINDRO, ESPECIALMENTE DURANTE LOS PERIODOS DE BAJA DEMANDA DE FUNCIONAMIENTO DEL MOTOR. LA VALVULA (32) COMPRENDE UNA MARIPOSA (26) DISPUESTA AGUAS ARRIBA DE UNA LUMBRERA DE ADMISION (14) Y CONTROLADA PARA MANTENERSE EN UNA CONDICION ABIERTA DURANTE DICHOS INTERVALOS, Y UN PISTON (80) QUE PUEDE MOVERSE RESPECTO A UNA ABERTURA (76) EN RESPUESTA A UNA DIFERENCIA DE PRESION CREADA EN PARTE POR LA OPERACION DE UNA VALVULA ELECTROMAGNETICA COOPERANTE (54), DE MODO CUANDO EL PISTON SE MUEVE PARA DESCUBRIR LA ABERTURA, UNA CANTIDAD PREDETERMINABLE DE FLUIDO, DENTRO DEL CILINDRO, PUEDE PURGARSE DEL MISMO A MEDIDA QUE EL PISTON DEL CILINDRO SE MUEVE A TRAVES DE SU CICLO DE COMPRESION.
