Abstract
UN APARATO DE PISTON PARA USO EN UN CILINDRO DE DESVIACION CONTROLADA INCLUYE UN PISTON EN FORMA RECTILINEA (10A) QUE TIENE AL MENOS UN CIERRE LATERAL (22A,22A ) QUE SE EXTIENDE LONGITUDINALMENTE EN UNA RANURA (12A,12A ) EN CADA PARED LATERAL Y EN EL CIERRE EXTREMO (21) EN CADA EXTREMO DEL PISTON QUE SE EXTIENDE ENTRE LOS CIERRES LATERALES. LOS CIERRES LATERALES TIENEN AL MENOS UN PAR DE SUPERFICIES INTERSECTANTES (62,64) EN CADA EXTREMO DE ELLO QUE COOPERA CON UN CORRESPONDIENTE PAR DE SUPERFICIES DE CADA CIERRE LATERAL PARA MOVER LONGITUDINALMENTE EN RELACION AL PISTON Y LOS CIERRES LATERALES PARA MANTENER UN CIERRE CONTINUO PERIFERICO SOBRE EL PISTON. EL CIERRE CONTINUO ENGRANA LAS PAREDES LATERALES (26,26 ) DE UN CANAL (30) DENTRO DE UN EJE SOPORTE (32) DEL CILINDRO DE DESVIACION CONTROLADA (34) Y UNA SUPERFICIE DE CIERRE NO MOVIL (37) EN CADA UNO DE LOS DOS, DIQUES OPUESTOS (36,36A) AL OTRO EXTREMO DEL CANAL EN EL EJE SOPORTE (32) EL LATERAL Y LOS CIERRES EXTREMOS (22A,21) SE MUEVEN CON EL PISTON (10A) EN RELACION AL EJE SOPORTE (32) Y LAS SUPERFICIES DE CIERRE EN LOS DIQUES EXTREMOS.
