Abstract

SE PRESENTA UN VENTILADOR PARA SUMINISTRAR O EMITIR GAS RESPIRATORIO Y DE LOS CONDUCTOS AEREOS A Y DE UN SER HUMANO O ANIMAL RESPECTIVAMENTE. EL VENTILADOR CONSTA DE UNA VALVULA DE SEGURIDAD MULTI-FUNCION (6) SITUADA ENTRE UNA VALVULA DE CONTROL Y LOS CONDUCTOS AEREOS. LA VALVULA DE SEGURIDAD (6) RESULTA AFECTADA EN SU DIRECCION DE CIERRE POR DOS MUELLES (13), QUE APLICAN UNA FUERZA QUE CORRESPONDE A UNA PRESION PREDETERMINADA Y EN SU DIRECCION DE APERTURA POR UN PISTON DE MUELLE CARGADO (22), QUE APLICA UNA FUERZA QUE EXCEDE LA FUERZA DE LOS MUELLES (13). AL ENCENDER EL VENTILADOR, SE CONECTA UN ELECTROMAGNETO (20). EL ELECTROMAGNETO (20) TIRA EL PISTON (22) CONTRA LA FUERZA DE LA CARGA DE MUELLE (21), Y LA VALVULA DE SEGURIDAD (6) SE CIERRA. POR MEDIO DE UN DISPOSITIVO DE CONTROL, SE PUEDE SUPERVISAR LA PRESION EN LA SECCION DE INSPIRACION (3) Y DESCONECTAR EL ELECTROMAGNETO (20) EN UNA SOBREPRESION PROGRAMADA. CUANDO SE PRODUCE EL FALLO DE CORRIENTE, LA VALVULA DE SEGURIDAD (6) SE ABRE YEL AIRE PUEDE PASAR A TRAVES LA VALVULA DE SEGURIDAD (6) A LOS CONDUCTOS AEREOS.
