Abstract

DISPOSITIVO DE ARO DE ACIETE Y COMPRESION DE PISTONES PARA MOTORES DE COMBUSTION INTERNA. INVENCION SOBRE UN DISPOSITIVO DE ARO DE ACIERTE Y COMPRESION DE PISTONES PARA MOTORES DE COMBUSTION INTERNA, QUE TIENE UN PAR DE CARRILES (10, 10) INSTALADOS EN UNA MISMA RANURA DE ARO (CA) DEL PISTON (P) SEPARADA MEDIANTE UN ARO DE COMPRESION INTERMEDIO (20), CONTACTANDO AL MENOS UNA PORCION DE SU SUPERFICIE PERIFERICA (13) LA PARED DE CILINDRO (C), EMPUJANDOSE LOS PARES DE CARRIL (10, 10) RADIALMENTE HACIA FUERA CONTRA DICHA PARED DE CILINDRO (C) MEDIANTE UN ELEMENTO DE MUELLE (30) ENGANCHADO DENTRO DE LA RANURA DE ARO (CA). ESTA CONSTRUCCION PERMITE USAR PISTONES CON SOLO DOS RANURAS DE ARO, PORQUE LOS PARES DE CARRILES (10, 10) ACTUAN COMO ARO DE ACIETE, CUANDO EL ARO SEPARADOR INTERMEDIO (20) ACTUA TANTO EN EL CONTROL DE ACEITE COMO EN EL ESCAPE.
