FIELD: pumping fluids. SUBSTANCE: plate-like working member kinematically coupled with a generator of lateral reciprocations is set in a flowing passage. The working member is made of a flexible wavelike stress belt positioned in pivotal side fixtures. The belt is divided into separated parts edges of which are interconnected with springs. The generator of lateral reciprocations is coupled with one end of the belt and other end of the belt is a cantilever relatively the pivot of the side fixtures. The working member between the pivots of the side fixtures is made of rods. The separated parts of the member are pivotally interconnected. EFFECT: enhanced efficiency. 3 cl, 4 dwg
