Abstract

EL EQUIPO ABARCA UN CILINDRO (3) Y UN PISTON (7) QUE ESTA GUIADO SIN CONTACTO EN RELACION AL CILINDRO (3). ENTRE LAS SUPERFICIES (15,14) DE CAMISA DEL CILINDRO (3) Y DEL PISTON (7) SE DISPONE DE UN ESPACIO DE SELLADO (12) CON UNA SECCION TRANSVERSAL ANULAR UNIFORME MUY DELGADA. LAS AREAS (14,15) DE SUPERFICIE DE LA CAMISA (4) DEL CILINDRO Y EL PISTON (7) SON SUSTANCIALMENTE SUAVES Y CONSISTEN EN UN MATERIAL CON UN COEFICIENTE DE EXPANSION LINEAL MAS BAJO QUE EL ACERO. EL ESPACIO DE SELLADO Y LA GUIA CENTRAL DEL PISTON (7) EN LA CAMISA DEL CILINDRO SE ASEGURA MEDIANTE DOS GUIAS (8,9) ASEGURADAS RIGIDAMENTE AL ALOJAMIENTO (5). LAS INDICADAS GUIAS (8,9) SON ELASTICAS A LO LARGO DEL EJE (2) CENTRAL DE LA UNIDAD EMBOLOCILINDRO Y MUY RIGIDAS TRANSVERSALMENTE CON RESPECTO AL EJE (2) CENTRAL. LA DISPOSICION DE UN ESPACIO DE SELLADO ENTRE EL PISTON (7) Y EL CILINDRO (3) FORMADO CON LA AYUDAD DE ESTAS GUIAS (8,9) SE REALIZA SIN CONTACTO CON EL MINIMO ESPACIO Y POR ELLO SIN QUE EXISTA DESGASTE FRICCIONAL SOBRE LOS MATERIALES DE SELLADO, SIENDO GUIADOS LOS MOVIMIENTOS DEL PISTON (7) COMPLETAMENTE DE FORMA CENTRAL EN RELACION AL CILINDRO (3).
