Abstract
A.DISPOSITIF DE REGLAGE DE POMPES VOLUMETRIQUES OSCILLANTES A COURSE VARIABLE. B.IL COMPREND UN ARBRE 1 DE MANIVELLE OBLIQUE DONT LE DEPLACEMENT AXIAL PERMET DE REGLER L'EXCENTRICITE DE LA BIELLE 10. CETTE MANIVELLE 1 OBLIQUE A LA FORME D'UN MANCHON DE NUTATION ET LA BIELLE 10 EST MAINTENUE SUR LE MANCHON 1 PAR UNE ARTICULATION 11 A ROTULE, LA BAGUE EXTERIEURE DE L'ARTICULATION 11 ETANT MONTEE GLISSANTE ENTRE DEUX SURFACES 12 DE GUIDAGE. C.POMPES.A. VARIABLE STROKE OSCILLATING VOLUMETRIC PUMPS ADJUSTMENT DEVICE. B. IT INCLUDES AN OBLIQUE CRANK SHAFT 1 WHOSE AXIAL DISPLACEMENT ALLOWS THE ECCENTRICITY OF THE CONNECTING ROD 10 TO BE ADJUSTED. THIS CRANK 1 OBLIQUE IN THE SHAPE OF A NUTATION SLEEVE AND THE ROD 10 IS HELD ON SLEEVE 1 BY A ARTICULATION 11 WITH A BALL JOINT, THE EXTERNAL RING OF THE JOINT 11 BEING SLIDING FITTED BETWEEN TWO GUIDING SURFACES 12. C. PUMPS.
