Abstract

L'INVENTION A POUR OBJET UN DISPOSITIF DE CONTROLE DE LA DECELERATION ETOU DE L'ACCELERATION DU PISTON D'UN VERIN AU VOISINAGE DES POINTS MORTS DE FIN DE COURSE DU PISTON. LE VERIN 1 A SON PISTON 3 POSSEDANT AU MOINS UN BOSSAGE 17A COAXIALEMENT ALIGNE AVEC CELUI-CI ET DESTINE A PENETRER, DE FACON ETANCHE, DANS UN ALESAGE BORGNE 20 PREVU DANS LE FOND 5 ASSOCIE DU VERIN 1 ET COMMUNIQUANT AVEC L'ATMOSPHERE. CE BOSSAGE 17A POSSEDE AU MOINS UN DEGAGEMENT DE MATIERE 19 TEL QUE LA SECTION TRANSVERSALE DU BOSSAGE AUGMENTE AU FUR ET A MESURE QU'IL PENETRE DANS L'ALESAGE 20. AINSI, LA VOIE D'ECHAPPEMENT PRINCIPAL DU FLUIDE REFOULE PAR LE PISTON 3 EST OBTUREE PROGRESSIVEMENT ET NON INSTANTANEMENT. L'INVENTION S'APPLIQUE NOTAMMENT AUX VERINS PNEUMATIQUES.THE OBJECT OF THE INVENTION IS A DEVICE FOR CONTROLLING THE DECELERATION AND / OR THE ACCELERATION OF THE PISTON OF A CYLINDER IN THE NEARBY OF THE PISTON LIMIT DEAD POINTS. THE CYLINDER 1 HAS ITS PISTON 3 HAVING AT LEAST ONE BOSS 17A COAXIALLY ALIGNED WITH THIS AND INTENDED TO ENTER, TIGHTLY, IN A BORAGE BORGNE 20 PROVIDED IN BOTTOM 5 ASSOCIATED WITH CYLINDER 1 AND COMMUNICATES WITH THE ATMOSPHERE. THIS BOSS 17A HAS AT LEAST ONE MATERIAL CLEARANCE 19 SUCH AS THE CROSS-SECTION OF THE BOSS INCREASES AS IT ENTERS BALE 20. THUS, THE MAIN EXHAUST PATH OF THE FLUID DELIVERED BY PISTON 3 IS CLOSED PROGRESSIVELY AND NOT INSTANTLY. THE INVENTION APPLIES IN PARTICULAR TO PNEUMATIC CYLINDERS.
