FLEXIBLE-HOSE MIXING PUMP FOR PASTY SUBSTANCES Russian patent published in 2017 - IPC F04B43/12 F04B43/09 

FIELD: engines and pumps.

SUBSTANCE: mixing pump contains an annular cavity along the hose. Working chamber - channel is made of magnetoactive elastomer plastic, energised by running field generator. On the inner surface of the channel, a series of parallel counterpropagating rectilinear projections is made, which ensure a complete overlap of the section, when the pipeline is locally compressed.

EFFECT: invention allows to increase the efficiency of transporting highly viscous and pasty substances due to the use of travelling deformation waves of the working chamber-channel, ensuring the movement of the transported material with low shear stress, and the internal relief allows to prevent the reverse movement of the substance.
