Abstract

UN CILINDRO NEUMATICO DE DOBLE ACCION SE CARACTERIZA POR UN PAR DE ELEMENTOS OBTURADORES (20,21,Y 27,28) RESPECTIVAMENTE SITUADOS SOBRE CUALQUIERA DE LOS DOS LADOS DEL PISTON (4) MEDIANTE VARILLAS (19,23,24) DESLIZANTEMENTE MONTADOS EN ORIFICIOS LONGITUDINALES FORMADOS EN EL PISTON (4). AL INICIO DE LA CARRERA DE VUELTA DEL PISTON DEL CILINDRO, LA VARILLA (19) Y SU ELEMENTO OBTURADOR ASOCIADO (20,21) ESTA EN UNA POSICION EXTENDIDA Y SIRVE PARA OBTURAR EL PRINCIPAL ORIFICIO DE ESCAPE (13'',14'') MIENTRAS EL PISTON (4) ESTA TODAVIA RELATIVAMENTE ALEJADO DEL EXTREMO DE SU CARRERA DE VUELTA. DURANTE LA CARRERA DE VUELTA DEL PISTON (4), EL AIRE PUEDE ESCAPARSE UNICAMENTE A TRAVES DEL ORIFICIO DE ESCAPE AUXILIAR (15'') Y EL MOVIMIENTO ES AMORTIGUADO. LA CARRERA DE VUELTA DEL CILINDRO ESTA AMORTIGUADA DE MODO SIMILAR SOBRE UNA DISTANCIA RELATIVAMENTE LARGA MEDIANTE EL ELEMENTO OBTURADOR (27,28) QUE ADOPTA UNA POSICION EXTENDIDA Y CIERRA EL PRINCIPAL ORIFICIO DE ESCAPE (13,14), ESCAPANDOSE EL AIRE A TRAVES DEL ORIFICIO DE ESCAPE AUXILIAR (15).
