Abstract

LOS EQUIPOS TIENEN UNA PLACA INFERIOR PERFORADA POR ABERTURAS DE SALIDA DEL REFRIGERANTE DEL CORAZON, UNA PLACA SUPERIOR (26), UNAS COLUMNAS PUNTALES (28) QUE UNEN LAS PLACAS, Y UNAS GUIAS DESTINADAS PARA UNOS RACIMOS DE MANDO DESPLAZABLES VERTICALMENTE ENTRE UNA POSICION DONDE SON INSERTADAS EN EL CORAZON Y UNA POSICION DONDE SON EXTRAIDAS DE ESTE ULTIMO, ALGUNAS AL MENOS DE ESTAS GUIAS TIENEN CADA UNA UN TRAMO SUPERIOR (30) QUE HACE SALIENTE POR ENCIMA DE LA PLACA SUPERIOR (26) Y UN TRAMO INFERIOR (32) QUE SE EXTIENDE ENTRE LAS PLACAS Y COLOCADO EN UNA COLUMNA PUNTAL RESPECTIVA (28). CADA GUIA DE RACIMO CONSTITUYE UN CARTUCHO INSERTABLE DENTRO DE UNA COLUMNA RESPECTIVA (28), PROVISTA DE UNA BRIDA (66, 86A) DE FIJACION A LA PLACA SUPERIOR (26) Y PROVISTA EN SU PARTE BAJA DE MEDIOS ELASTICOS DE CENTRADO DENTRO DE LA COLUMNA.
