摘要：
A continuously adjustable liquid mixing device (10) for intermixing selectively adjustable volumes of several liquids comprises a body (12) for holding a plurality of volumes of said liquids including a recess (14) at an upper end. A mechanism is provided for drawing up the volumes of liquid into the body and thereafter expelling the same from a lower end. A volume adjusting selecting mechanism (22) is provided for at least one of the volumes including a rotary element (26) mounted in the recess and frictionally engaging (28) a wall surface (14a) thereof for retaining a selected volume that is desired. A rotary drive system (34) is provided for rotating the volume adjustment mechanism (22) and is readily accessible externally of the body for convenient manipulation to select a desired volume. The drive system (34,36) is movable between an outer operating position for easy manipulation and a retracted position when not in use.
