In article are considered non-stationary processes pulsing ejector stage liquid-recirculating vacuum pump, intentionally for intensify of the interaction flow mixed gas in pulsing ejector. Pulsation source is a periodic variation of the ejector configuration elements using choppers active gas flows. It is designed mathematical model, taking into account loss amount motion on friction (the travel losses), as well as loss of the pressure in area of the change the section of the flow (the local losses) for channel with constant cross-sections (the ejector with cylindrical camera of the mélange).
