(under subclass 565.01) Subject matter including a pump wherein a motive fluid and a driven fluid are brought into intimate contact in an enclosed flow path, the motive fluid having a higher velocity than the driven fluid and imparting energy to the driven fluid by the action of entrainment contact. [figure] [caption]Figure 1: A typical example of the subject matter. A - Pump; B - Tank or reservoir; C - Jet-aspiration pump; D - Diffuser; E - Vent; F - Drain valve.
