Abstract

LA INVENCION SE REFIERE A UN GATO MULTIPLE DE POR LO MENOS TRES ELEMENTOS, CUYOS DOS PISTONES (3, 8) Y DOS CILINDROS (2, 7) QUE DEFINEN UNA GRAN (11) Y UNA PEQUEÑA (12) CAMARA DE UN PRIMER CILINDRO, Y UN GRAN (13) Y UNA PEQUEÑA (14) CAMARA DE UN SEGUNDO CILINDRO. SEGUN LA INVENCION: A) UN PRIMER CONDUCTO INTERNO (15, 16, 17) CONECTA LA CAMARA GRANDE (11) DEL PRIMER CILINDRO A UN PRIMER CONDUCTO EXTERNO (20); B) UN SEGUNDO CONDUCTO INTERNO (22 PRIMER CILINDRO A UN SEGUNDO CONDUCTO EXTERNO (26); C) UN TERCER CONDUCTO INTERNO (29 DEL SEGUNDO CILINDRO A UN TERCER CONDUCTO EXTERNO (34); Y D) UN CUARTO CONDUCTO INTERNO (31 (14) DEL SEGUNDO CILINDRO A UN CUARTO CONDUCTO EXTERNO (35). UNA APLICACCION ES LA REALIZACION DE UNA FLECHA TELESCOPICA QUE PRESENTA UNA FLEXIBILIDAD DE USO SATISFACTORIA.
