FIELD: transportation.
SUBSTANCE: group of inventions relates to a capillary structure for passive directed fluid transfer. Structure contains capillary 20 with direction 40 forward and direction 45 back, passing in plane x-y, and depth passing in direction z. Capillary comprises the first and second capillary cells 25, each of which has an expanding section with a rear end, a front end and a width in the y direction. Width increases from rear end to front end. Rear end of divergent section of second cell 25 is connected with front end of divergent section of first cell 25 to form transition section with sharp decrease in width from front end of divergent section of first cell 25 to rear end of divergent section of second cell 25. Depth in transition section is less than depth in each expanding section.
EFFECT: improved efficiency of fluid medium transfer.
