Abstract

VALVULA MULTIPLICADORA DE PRESION EN CILINDROS DE FRENADO. SE INSERTA LA VALVULA (26) EN UN CILINDRO PARA INSTALACIONES HIDRAULICAS DE FRENADO, CARACTERIZADO PORQUE COMPRENDE UN RACOR DE ALIMENTACION (4) Y OTRO (5), UN PISTON (9) DE GRADA MOVIL QUE ACTUA BAJO LA ACCION DE UN PEDAL, UNAS CAMARAS ANULARES Y UN SISTEMA DE JUNTAS. CUANDO SE ALCANZA LA PRESION DE FUNCIONAMIENTO EN LA CAMARA ANULAR (23) SE COMUNICA A LOS ELEMENTOS DE FRENADO; ESTA PRESION ACTUA SOBRE LA JUNTA (29), VENCE LA FUERZA DEL MUELLE (31) Y LA VALVULA (26) SE ABRE, CON LO CUAL QUEDA DESCUBIERTO EL PASO (33), QUE PERMITE AL LIQUIDO COMPRIMIDO EN (23) REFLUIR AL RACOR DE ALIMENTACION (4); CUANDO DESCIENDE LA PRESION, LA VALVULA (26) SE CIERRA. LA CONDICION DE MULTIPLICACION DE PRESION QUEDA DEFINIDA POR LA RELACION ENTRE LA FUERZA EJERCIDA POR EL MUELLE (31) Y AREA DE SECCION DE ORIFICIO (28).
