Abstract
EL DISPOSITIVO DE CIERRE COMPRENDE AL MENOS DOS CILINDROS DE PRESION (20,25) CUYOS PERNOS DE PRESION SE CONECTAN POR BARRAS DE PERNOS (28) CON EL PORTADOR DE FORMA (13) Y CUYOS ESPACIOS DE ALTA PRESION (52) ESTAN EN CONEXION POR CANALES DE SOBRECORRIENTE (42) CON LOS ESPACIOS DE BAJA PRESION (50). LOS CANALES DE SOBRECORRIENTE (42) SE BLOQUEAN CON AYUDA DE CUERPOS DE VALVULA (43). EN EL EJE SIMETRICO (A-A) ESTAN COLOCADOS UN CILINDRO IMPULSOR (27- 47B) PARA CIERRE Y ABERTURA DE LA FORMA DE INYECCION (78) ASI COMO UN CILINDRO DE NIVEL (21,26) CONECTADO CON EL PORTADOR DE FORMA (13) EN CONEXION ABIERTA CON LOS ESPACIOS DE BAJA PRESION (50). LOS VOLUMENES MAXIMOS DE ESPACIOS DE BAJA PRESION MAS EL ESPACIO DE NIVEL (51) DEL CILINDRO DE NIVEL (21,26) CORRESPONDE A LOS VOLUMENES MAXIMOS DE LOS ESPACIOS DE ALTA PRESION (52). LOS CILINDROS FORMADOS POR MANGUITOS DE ACERO (20;21) DEL CILINDRO DE PRESION (20,25) Y DEL CILINDRO DE NIVEL (21,26) SE COMPRENDEN CONJUNTAMENTE MEDIANTE TAPAS DE CILINDROGENERALES EN UN AGREGADO. EL CILINDRO IMPULSOR (27,47B) SE RODEA COAXIALMENTE POR EL MANGUITO DE ACERO (21) DEL CILINDRO DE NIVEL (21,26).LOS MANGUITOS DE ACERO (20) DE AL MENOS DOS CILINDROS DE PRESION (20,25) ESTAN COLOCADOS SIMETRICAMENTE AL CILINDRO IMPULSOR (27,47B). ASI SE ALCANZA UNA PREPARACION ECONOMICA EN DISPOSITIVOS DE CIERRE CON MONTAJE DE POCO ESPACIO.
