Abstract

UN INTERRUPTOR A PRESION ACCIONADO POR DIAFRAGMA DILATABLE (10) QUE TIENE UNA ARANDELA DE RESORTE BELLEVILLE (30) CON UN DISCO DE RESORTE EMBUTIDO (34) ENCAJADO EN EL CENTRO Y SOPORTADO SOBRE LA PERIFERIA INTERIOR DE LA ARANDELA QUE RESISTE EL MOVIMIENTO DEL DIAFRAGMA (24). UN ELEMENTO ACCIONADOR (36) ESTA POLARIZADO POR RESORTE CONTRA EL DISCO Y TIENE UN EXTREMO DE UN RESORTE DE PALANCA (46) REGISTRADO SOBRE SI CON EL OTRO EXTREMO CONECTADO A UNA CUCHILLA DE CONTACTO DE INTERRUPTOR (48) INICIALMENTE EN UNA CONDICION DE CIRCUITO ABIERTO. SEGUN EL DIAFRAGMA INICIALMENTE SE EXPERIMENTA UNA PRESION DE AUMENTO A UN PRIMER NIVEL, EL ACCIONADOR DE DISCO EMBUTIDO INVIERTE LA CURVATURA Y MUEVE AL ACCIONADOR A EFECTUAR EL MOVIMIENTO DE LA CUCHILLA DE CONTACTO HACIA UNA CONDICION DE CIRCUITO CERRADO. ADEMAS SEGUN LA PRESION AUMENTA A UN SEGUNDO NIVEL, LA ARANDELA DE BELLEVILLE SE PARTE Y PROVOCA ADEMAS UN MOVIMIENTO DEL ACCIONADOR EN LA MISMA DIRECCION Y HACE EL MUELLE DE LA PALANCA SE PARTA Y DEVUELVA AL ELEMENTO DE CUCHILLA DE CONTACTO A LA CONDICION DE CIRCUITO ABIERTO. SEGUN CAE LA PRESION A UN TERCER NIVEL ENTRE EL PRIMER Y EL SEGUNDO NIVEL, LA ARANDELA DE BELLEVILLE SE PARTE DE NUEVO Y RETRAE EL ACCIONADOR Y HACE QUE EL RESORTE DE LA PALANCA VAYA AL CENTRO Y MUEVA DE NUEVO LA CUCHILLA DE CONTACTO EN CONDICION DE CIRCUITO CERRADO. SEGUN LA PRESION DECRECE A UN CUARTO NIVEL MENOR QUE EL PRIMER, EL DISCO EMBUTIDO SE PARTE Y SE RETRAE EL ACCIONADOR SUFICIENTEMENTE PARA HACER QUE EL MUELLE DE LA PALANCA PERMITA QUE LA CUCHILLA DE CONTROL VUELVA A LA CONDICION DE CIRCUITO ABIERTO INICIAL.
