Abstract

LA BOMBA DE VACIO INCLUYE DOS PARES DE MONTAJES DE PISTON Y CILINDRO MONTADOS EN LADOS OPUESTOS Y UN CIGUEÑAL EN UN PLENO COMUN CON LAS ENTRADAS DE GAS PARA EL PRIMER Y SEGUNDO CILINDRO DE UN PRIMER PAR DE MONTAJES DE PISTON Y CILINDRO, QUE ES CONECTADA AL DISPOSITIVO PARA SER EVACUADO Y LA SALIDA DE GAS DEL MISMO QUE ES CONECTADA A UNA SALIDA COMUN QUE TIENE UNA VALVULA DE UNA SOLA DIRECCION SESGADA DE MUELLE CONTROLANDO LA SALIDA A UN PASO CONECTADO A LA ENTRADA DE UN TERCER CILINDRO EN DICHO SEGUNDO PAR DE MONTAJES DE PISTON Y CILINDRO. LA SALIDA DE GAS DEL TERCER CILINDRO ESTA CONECTADA A LA ENTRADA DEL CUARTO CILINDRO Y A LA SALIDA DE GAS DEL CUARTO CILINDRO ESTA CONECTADA A LA SALIDA DE GAS DEL CUARTO CILINDRO ESTA CONECTADA A LA SALIDA COMUN A TRAVES DE LA VALVULA DE UNA SOLA DIRECCION, SESGADA Y DE MUELLE. CADA CILINDRO ESTA PROVISTO CON UNA CABEZA DE CILINDRO QUE TIENE UN PAR DE VALVULAS DE UNA SOLA DIRECCION CONTROLANDO LOS PUNTOS DE ENTRADA Y SALIDA EN DONDE LA VALVULA DE UNA SOLA CIRECCION QUE CONTROLA EL PUNTO DE ENTRADA DE GAS, ACTUA COMO UNA VALVULA DE REDUCCION DEL MOMENTO DE TORSION PARA REDUCIR LA CANTIDAD DE TORSION NECESARIA PARA MOVER EL PISTON DE LA CABEZA DEL CILINDRO EN EL GOLPE INICIAL DEL PISTON. CADA CILINDRO ESTA PROVISTO CON UN REVESTIMIENTO EN FORMA DE FUNDA QUE TIENE UNA CAPA DE OXIDO DE GRAN RESISTENCIA POR ESO CADA PISTON ESTA PROVISTO CON UNA CAPA DE POLITETRAFLUORETILENO CON EL PROPOSITO DE REDUCIR LA FRICCION.
