Abstract

DISPOSITIF DE DISTRIBUTION DE LIQUIDE OSCILLO-ROTATIF AVEC RESSORT ET SA M É THODE La présente invention concerne un dispositif de distribution de produit liquide comportant une partie fixe et une partie mobile ; la partie fixe comprenant un orifice d’aspiration, un orifice de refoulement, un corps comportant une cavité dans laquelle débouchent lesdits orifices, ladite cavité étant apte à recevoir partiellement la partie mobile, le volume restant formant une chambre de vidange ; la partie mobile étant apte à se déplacer partiellement dans la cavité de la partie fixe et comprenant un piston, un élément d’entrainement du piston, un ressort axial, un conduit s’étendant le long de la circonférence du piston, ledit conduit permettant d’une part des positions permettant une communication fluidique entre la chambre de vidange et un seul desdits orifices et d’autre part des positions de commutation dans lesquelles toute communication fluidique entre la chambre de vidange et chacun desdits orifices est interdite, une came apte à transformer la rotation de l’élément d’entrainement en mouvement oscillo-rotatif du piston. Le dispositif selon l’invention est caractérisé en ce que le ressort axial est apte à absorber de l'énergie durant une phase d’aspiration du liquide et à la restituer durant une phase de refoulement du liquide, ledit ressort étant positionné autour du piston qui se trouve sur la partie mobile située dans la cavité du corps.
