Abstract
Cette pompe est du type de celles constituées de deux cylindres de diamètres différents, dans chacun desquels peut coulisser un piston de diamètre correspondant avec une tige de piston creuse reliant ces deux pistons et faisant communiquer entre eux ces deux cylindres, un clapet d'admission du fluide dans le cylindre de grand diamètre, un clapet de refoulement du fluide hors de ce même cylindre, et des moyens pour animer les deux pistons et la tige creuse les reliant d'un mouvement de coulissement alternatif dans leurs cylindres respectifs. Elle est agencée de façon que la face des pistons opposée à celle qui est en contact avec le rpoduit à traiter soit toujours en contact avec du solvant
