Abstract
Изобретение относитс к объемным насосам. Цель изобретени - увеличение КПД. В кольцевой проточке 12 ротора, сопр женной с выступом 10 профилированной крышки 3, размещены с образованием рабочих камер разделители 7. На внутренней поверхности выступа 10 между каналами 8, 9 впуска и выпуска выполнена полуокружна канавка 11. Разделители 7 выполнены в виде эластичных мембран. Мембраны 7 закреплены на роторе 5 с образованием между ротором 5 и крышкой 3 подмембранных полостей 15. Полости 15 сообщаютс с коллектором 13 через перепускные каналы 14. В момент прохождени разделител 7 под канавкой 11 подмембранна полость 15 заполн етс рабочей средой из коллектора 13. Мембрана 7 взаимодействует с поверхностью канавки 11 с образованием между каналами 8, 9 впуска и выпуска рабочих. 4 ил.This invention relates to positive displacement pumps. The purpose of the invention is to increase efficiency. In the annular groove 12 of the rotor, coupled with the protrusion 10 of the profiled cover 3, the separators 7 are arranged to form working chambers. A semi-circular groove 11 is formed on the inner surface of the projection 10 between the inlet and outlet channels 8, 9. The separators 7 are made in the form of elastic membranes. The membranes 7 are fixed on the rotor 5 to form submembrane cavities 15 between the rotor 5 and the lid 3. The cavities 15 communicate with the collector 13 through the bypass channels 14. At the time the separator 7 passes through the groove 11, the submembrane cavity 15 is filled with working medium from the collector 13. Membrane 7 interacts with the surface of the groove 11 with the formation between the channels 8, 9 of the inlet and outlet workers. 4 il.
