Abstract

Dispositif de pompage comprenant une pompe connectée pour faire circuler un fluide d'un réservoir 20 à un point de destination le long d'un trajet qui comprend un passage 42, un volume définissant une chambre de pompage 33 dans ce passage, cette chambre de pompage ayant une capacité prédéterminée et des moyens à membrane 36 qui définissent au moins un volume de fluide pompé dans une chambre de pompage, un dispositif chauffant comprenant une certaine quantité de fluide de pompage, une chambre de chauffe 30 destinée à contenir cette quantité de fluide de pompage, la chambre de chauffe étant agencée pour exercer une force sur les moyens à ladite membrane 36 afin de réduire le volume de fluide pompé de la chambre de pompage 33 lorsque la pression de ladite quantité de fluide de pompage augmente et un élément chauffant 18 contenu dans la chambre de chauffe 30 et servant à chauffer ladite quantité de fluide de pompage et, par ce moyen, à augmenter la pression et le volume de ladite quantité de fluide de pompage et des moyens 10 de commande de l'élément chauffant qui émettent des impulsions électriques servant à exciter cet élément chauffant 18 par intermittence.
