Abstract

EL PROBLEMA TECNICO DEL CUAL PARTE LA INVENCION, ES QUE UN NUMERO DE REVOLUCIONES DEMASIADO BAJO CON MARCHA EN VACIO EN LOS ACOPLAMIENTO POR ROZAMIENTO VISCOSO, TIENE POR CONSECUENCIA QUE EL ACOPLAMIENTO EN CASO NECESARIO NO EMBRAGUE. POR TANTO, LA TAREA DE LA INVENCION CONSISTE MEDIANTE ELEMENTOS CONSTRUCTIVOS SENCILLOS ALCANZAR UN AUMENTO DEL NUMERO DE REVOLUCIONES CON MARCHA EN VACIO Y CON ELLO UN EMBRAGUE SEGURO DEL ACOPLAMIENTO. ESTA TAREA SE SOLUCIONA DE ACUERDO CON LA INVENCION, PORQUE EN EL CANAL DE RETORNO DEL ACOPLAMIENTO POR ROZAMIENTO VISCOSO, ES DECIR, ENTRE LA CAMARA DE TRABAJO Y LA CAMARA DE RESERVA, ESTA DISPUESTA UNA LLAMADA VALVULA DE PRESION DIFERENCIAL, LA CUAL CON UNA PRESION DIFERENCIAL DEFINIDA ENTRE LA CAMARA DE TRABAJO Y LA CAMARA DE RESERVA, ABRE HACIA LA CAMARA DE RESERVA. CON PREFERENCIA ESTA VALVULA DE PRESION DIFERENCIAL ESTA FORMADA COMO VALVULA ESFERICA CARGADA POR MUELLE, LA CUAL TIENE LA VENTAJA DE QUE ES DE EMPLEO, AJUSTE Y REGULACION SENCILLOS. EL CAMPO DE APLICACION DE ESTOS ACOPLAMIENTOS POR ROZAMIENTO VISCOSO ES EL ACCIONAMIENTO DE VENTILADORES PARA LA REFRIGERACION DE MOTORES DE VEHICULOS.
