Abstract

DE ACUERDO CON UN EJEMPLO ILUSTRATIVO DEL INVENTO, EL CILINDRO ESTA SUBDIVIDIDO POR UNA PARED DE SEPARACION ESTACIONARIA EN DOS CAMARAS DE COMPRESION. SE INTRODUCE CON AJUSTE UN PRIMER PISTON DESDE LA ATMOSFERA A TRAVES DE UNA PARED EXTREMA DEL CILINDRO HACIA UNA PRIMERA CAMARA DE COMPRESION SITUADA EN UN LADO DE LA PARED DE SEPARACION. UN SEGUNDO PISTON SE EXTIENDE CON AJUSTE A TRAVES DE DICHA PARED DE SEPARACION DESDE LA PRIMERA CAMARA DE COMPRESION SOBRE UN LADO DE DICHA PARED HASTA UNA SEGUNDA CAMARA DE COMPRESION SOBRE EL OTRO LADO DE LA PARED. HAY UN GAS DE BAJA PRESION EN LA PRIMERA CAMARA Y UN GAS DE MAYOR PRESION EN LA SEGUNDA CAMARA. SE SITUAN UNOS CONTRAFUERTES EN EL PRIMER Y EN EL SEGUNDO PISTON. PARA QUE EL PRIMER PISTON SE MUEVA POR EL INTERIOR DEL CILINDRO, LOS CONTRAFUERTES SE ENGANCHAN DESPUES DE UNA TRAYECTORIA DETERMINADA DE DICHO PISTON EN EL CILINDRO.
