Abstract

EN UNA PROTESIS DE COMPUERTA DE CORAZON EN LA QUE LAS SUPERFICIES INTERIORES (10A) DEL ANILLO DE COMPUERTA (10) SE ESTRECHA CONTINUAMENTE EN DIRECCION DEL PASO DE FLUIDO , SE HA PREVISTO UNA COLOCACION ESPECIAL DEL CUERPO DE CIERRE (11). EN EL ANILLO DE COMPUERTA (10) SE ENCUENTRAN DISMINUCIONES (18) EN FORMA SECTORIAL EN LAS QUE PENETRA EN CADA UNA UN VASTAGO DE ALOJAMIENTO DEL CUERPO DE CIERRE (11). AL MOVIMIENTO DE APERTURA Y CIERRE SOBRESALE EL VASTAGO EL FONDO DE LA DISMINUCION (18) EN FORMA DE UN LIMPIAPARABRISAS. DE ESTA FORMA SE EVITA LA FORMACION DE TROMBA EN LA ZONA DE LOS ALOJAMIENTOS.
