Abstract

VALVULA DE AIRE DE BAJA FRICCION CON FORMACION REDUCIDA DE HIELO PARA UN MOTOR DE AIRE ALTERNATIVO PARA TRANSMITIR CALOR DEL AIRE COMPRIMIDO ENTRANTE A LAS CAPERUZAS DE LAS VALVULAS, PARA EVITAR LA FORMACION DE HIELO Y UN MECANISMO DE BAJA FRICCION PARA EL CURSOR DE LA VALVULA. EL DISEÑO TIENE UNA CARCASA CON UNA CAMARA DE AIRE Y EN SU INTERIOR UN CURSOR QUE TIENE DOS CAPERUZAS QUE TAPAN ALTERNATIVAMENTE LAS BOCAS QUE CONDUCEN A LAS CAMARAS SUPERIOR E INFERIOR DEL PISTON DEL MOTOR DE AIRE. LA VALVULA DE DESPLAZAMIENTO TIENE UN MUELLE EN UNA ABERTURA DEL CURSOR JUNTO CON PLACAS DE RETENCION PARA DESPLAZAR LA VALVULA DE MODO QUE ESTA SE SITUE EN UNA DE LAS DOS POSICIONES DE FUNCIONAMIENTO. LA CAMARA A PRESION, CON LAS ALETAS, ABERTURAS Y OTROS MEDIOS DE TRANSMISION DE CALOR EN EL CURSOR ASEGURA QUE LAS CAPERUZAS SE CALIENTEN PARA EVITAR EL HIELO.
