Abstract:

A device for transmitting equal amounts of liquid simultaneously to a plurality of locations. An airtight enclosure has a bottom wall formed with a plurality of inwardly opening wells of equal volumes all having bottom openings through which liquid can flow out of the wells. A plurality of exteriorly located liquid-transmitting tubes communicate with the wells through the bottom openings, these tubes respectively having in their interiors valves which automatically close the tubes in response to suction in said interior space of the enclosure while opening said tubes in response to greater than atmospheric pressure in the interior of the enclosure. A liquid-supply header responds to less than atmospheric pressure in the space in the enclosure for delivering liquid thereto, this header communicating through tubular branches with the wells to transmit the liquid simultaneously to the wells while suction prevails in the interior space of the enclosure, this suction operating to automatically close the valves in the plurality of liquid-transmitting tubes so that in this way the wells are simultaneously filled with liquid. Then greater than atmospheric pressure is created in the space within the enclosure so as to push with this pressure the liquid simultaneously out of the several wells through the liquid-transmitting tubes while simultaneously opening the valves therein.
