Abstract

SE COLOCA UNA VALVULA CERRADA DE MANERA NORMAL (16) POR DEBAJO DEL SEPARADOR DE ACEITE (14) PARA ASEGURAR QUE SE REALIZA UNA PRESION DE ACEITE SUFICIENTE PARA LUBRICAR EL COMPRESOR (12). LA VALVULA (16) ES SENSIBLE A LA PRESION DIFERENCIAL ENTRE LA DESCARGA Y EL ECONOMIZADOR (20), DE TAL FORMA QUE SE PRODUCE UN ESTRANGULAMIENTO SOBRE UNA PORCION LIMITADA DE LA ENVOLTURA OPERANTE.
