Title (EN) PLURAL SCREW POSITIVE DISPLACEMENT MACHINES
(FR) MACHINE MULTI-ROTOR A DEPLACEMENT POSITIF
Abstract: front page image
(EN)A plural screw machine has a housing (1) in which intermeshing helically profiled rotors (6, 7) define working chambers of volumes, and thus pressures, which vary as the rotors rotate. To prevent a build-up of heat in the rotors, a small flow of evaporable liquid such as water is directed at portions of the rotors subjects to higher pressures. The flow rate of the liquid is too small to effect any substantial cooling of the gas through the machine.
(FR)La présente invention concerne une machine multi-rotor comportant un carter (1) recevant des rotors hélicoïdaux engrenants (6, 7). Cette machine définit des chambres de travail de volumes, et, par tant, de pressions, qui varient avec la rotation des rotors. Pour empêcher l'échauffement des rotors, un faible courant de liquide sujet à évaporation tel que l'eau est envoyé en des endroits des rotors subissant des pressions supérieures. Le débit de ce liquide est insuffisant pour provoquer un refroidissement notable du gaz traversant la machine.
