A vacuum pump comprising a wall configured to form a closed-off fluid volume, the wall being movable by means of a first force for producing a volume reduction of the closed-off fluid volume and, after a preceding volume reduction, the wall being movable by means of a second force for producing a volume increase in the closed-off fluid volume; an inlet port in fluid communication with the closed-off fluid volume, the inlet port having an inlet valve arranged to be connected to a vacuum space; an outlet port in fluid communication with the closed-off fluid volume, the outlet port including an outlet valve arranged to exhaust external to the closed-off fluid volume; and an elastically deformable material compressible by the first force and upon expansion, after termination of the first force, produces the second force, wherein the first force exhausts fluid from the closed-off fluid volume through the outlet port and the second force draws fluid from the vacuum space through the inlet port into the closed-off fluid volume.
L'invention concerne une pompe comprenant une paroi (3; 21, 22; 31, 32, 33) qui forme un volume fermé de fluide (1) et qui est mobile à l'aide d'une première force (F) en direction d'une réduction volumique et à l'aide d'une deuxième force - après une réduction volumique précédente en direction d'une augmentation volumique, et une première soupape (8) qui communique par un orifice d'admission (6) et une soupape de sortie (9) d'une conduite de sortie (7) du volume fluidique (1). Cette conception est compacte, lorsque la pompe est réalisée sous la forme d'une pompe à vide dont le volume peut être réduit par la première force externe qui est exercée sur une matière élastiquement déformable (2; 21, 22; 33) dont la force de rappel constitue la deuxième force agissant à l'encontre de la pression négative au terme de l'application de la force externe.
