Abstract

CE DISPOSITIF OU FREIN EST DESTINE A EMPECHER OU LIMITER LE DEPLACEMENT AXIAL DE L'AXE CREUX DANS UN PISTON A MOUVEMENT ALTERNATIF D'UNE MACHINE OU APPAREIL A PISTON(S) DE TYPE QUELCONQUE. IL EST CONSTITUE D'UN RESSORT 3 COURBE EN U A BRANCHES D'EXPANSION QUI TENDENT A S'ECARTER L'UNE DE L'AUTRE. LES EXTREMITES LIBRES 4 ET 5 DES BRANCHES SONT RECOURBEES VERS L'EXTERIEUR ET CONFORMEES DE MANIERE QU'ELLES PUISSENT PASSER A TRAVERS LE TROU 10 DE L'AXE 2 DU PISTON 1 LORSQUE LE RESSORT EST COMPRIME. LA TETE FERMEE 6 DU RESSORT 3 POSSEDE UNE LARGEUR PLUS GRANDE QUE LA DISTANCE ENTRE LES DEUX BRANCHES A PROXIMITE DE LA TETE.THIS DEVICE OR BRAKE IS INTENDED TO PREVENT OR LIMIT THE AXIAL DISPLACEMENT OF THE HOLLOW SHAFT IN A PISTON WITH ALTERNATIVE MOVEMENT OF A MACHINE OR APPARATUS WITH PISTON (S) OF ANY TYPE. IT IS CONSISTING OF A 3 U-CURVED SPRING WITH EXPANSION BRANCHES WHICH TEND TO MOVE AWAY FROM ONE ANOTHER. THE FREE ENDS 4 AND 5 OF THE BRANCHES ARE CURVED OUTWARDS AND COMPLIED SO THAT THEY COULD PASS THROUGH HOLE 10 IN AXIS 2 OF PISTON 1 WHEN THE SPRING IS COMPRESSED. THE CLOSED HEAD 6 OF THE SPRING 3 HAS A WIDTH GREATER THAN THE DISTANCE BETWEEN THE TWO BRANCHES NEAR THE HEAD.
