Beschreibung
Zusammenfassung:	A regenerative fluid pump ( 10 ) comprises a rotor having rotor blades for compressing fluid on two fluid flow paths, the first of which extends between a first pump inlet ( 12 a) and a first pump outlet (14a), and a second of which extends between a second pump inlet ( 12 b) and a second pump outlet ( 14 b). The pump comprises a stator comprising a plurality of concentric channels ( 16 ), each of which comprises: a pumping channel portion ( 18 ) along which said rotor blades move for compressing said fluid between an inlet and an outlet of the pumping channel; and a stripper channel portion ( 20 ) (shown in broken lines) which allows movement of said rotor blades from said outlet to said inlet of the pumping channel portion. Each concentric channel ( 16 ) comprises two pumping channel portions ( 18 ) and two stripper channel portions ( 20 ).
