Abstract
A fluid transferer, including a volume changing part; a reciprocating member configured to reciprocate to expand a volume of the volume changing part to draw a fluid from an upstream side of a transfer direction and compress the volume thereof to transfer the drawn fluid to a downstream side thereof with pressure; and a drive controller configured to control reciprocation of the reciprocating member such that a time for compressing the volume of the volume changing part is longer than a time for expanding the volume thereof.
