MAGNETICALLY DRIVEN ELECTROCHEMICAL MICROPUMP WITH LIQUID

摘要

The invention relates to a magnetically driven electrochemical micropump meant to circulate low quantities of liquid. According to the invention, the micropump comprises a cylindrical housing (1) provided with a cavity (2) wherein there is placed a liquid (3) subjected to circulation which is discharged by the pressure exerted by a swimmer (4) which is integral with an annular armature (5) made of ferromagnetic material driven by means of an annular magnet (6) placed outside the housing (1), whereto the internal pressure necessary to discharge the liquid (3) circulating outside through a microchannel (7) is controlled by means of a microvalve (8) placed at the upper part of the cavity (2).
