Abstract

LA BOMBA (10) TIENE UNA CARCASA (14) CON UNA PERFORACION (20) PARA RECIBIR UN CILINDRO (22) CON UN PISTON (26) ACCIONABLE POR MEDIO DE UNA EXCENTRICA (18). SOBRE EL MISMO EJE DEL CILINDRO (22), EN UNA SECCION MAS ANCHA (44) DE LA PERFORACION (20) SE ENCUENTRA LA CARCASA DE UNA VALVULA DE SALIDA (40). EL ESPACIO ANULAR (42) QUE RODEA A ESTA VALVULA (40) VA CERRADO CON UNA TAPADERA. EL CILINDRO DE LA BOMBA (22), LA VALVULA DE SALIDA (40) Y LA TAPADERA (56) SE SUJETAN A LA CARCASA DE LA BOMBA (14) MEDIANTE UN TORNILLO DE CIERRE (60) QUE SE ATORNILLA EN LA SECCION (44) DE LA PERFORACION. EL ESPACIO ANULAR (42) ACTUA, EN UNION CON UNA PERFORACION DE SALIDA (50) DE LA BOMBA, DISEÑADA COMO DIAFRAGMA, COMO UNA CAMARA DE AMORTIGUACION PARA EL LIQUIDO DE FRENO, QUE LLEGA DE FORMA DISCONTINUA EN ESTE TIPO DE BOMBAS. MEDIANTE ESTAS SENCILLAS CAMARAS DE AMORTIGUACION SE REDUCEN LAS VARIACIONES DE PRESION DEL LIQUIDO DE FRENO EVITANDO QUE AL FUNCIONAR LA BOMBA ENTRE EN VIBRACION LA CARROCERIA DEL AUTOMOVIL, LO QUE INHIBE EN GRAN MANERA LOS RUIDOS EN EL INTERIOR DEL MISMO.
