Abstract

UNA VALVULA (12) QUE FUNCIONA MEDIANTE UN SOLENOIDE MODULADO POR EL ANCHO DE UN IMPULSO Y UNA VALVULA QUE FUNCIONA MEDIANTE VACIO (14) SE ASOCIAN DE TAL FORMA QUE EL SISTEMA DE SANGRADO POSEA TANTO UN CONTROL EXACTO A UN FLUJO DE SANGRADO BAJO COMO LA CAPACIDAD DE MANEJAR FLUJOS MUCHO MAYORES. LAS DOS VALVULAS SE ENCUENTRAN EN PARALELO ENTRE EL BOTE Y EL DISTRIBUIDOR. POR DEBAJO DE UN CIERTO CICLO DE OCUPACION DE LA VALVULA QUE FUNCIONA MEDIANTE EL SOLENOIDE, SOLAMENTE ESTA ABIERTO SU CAMINO. EN CICLOS DE MAS ALTA OCUPACION, AMBOS CAMINOS DE FLUJO SE ENCUENTRAN ABIERTOS. SE SUMINISTRA UN ORIFICIO (46) EN EL CAMINO DEL FLUJO QUE CONTIENE LA VALVULA QUE FUNCIONA MEDIANTE EL SOLENOIDE DE FORMA QUE ESTA VALVULA SE ABRA DE FORMA INCREMENTADA, INCREMENTANDOSE TAMBIEN LA SEÑAL DE VACIO EN UNA ESPITA (44) QUE SE ENCUENTRA ENTRE EL ORIFICIO Y LA VALVULA QUE FUNCIONA MEDIANTE EL SOLENOIDE. ESTA SEÑAL DE VACIO SE APLICA A UN PUERTO DE CONTROL (34) DE LA VALVULA QUE ACTUA MEDIANTE VACIO PARA PROVOCAR QUE ESTA ULTIMA SE ABRA CUANDO SE ALCANCE UN CIERTO NIVEL DE FLUJO A TRAVES DE LA VALVULA QUE FUNCIONA MEDIANTE EL SOLENOIDE.
