<p>A liquid mixing system having a mixing cylinder (1) in which a movable piston (2) divides a liquid additive chamber (3) from a displacing liquid chamber (4). Displacing liquid, usually a proportion of a carrier liquid with which the additive liquid is to be mixed, is introduced to the displacing chamber to eject additive fluid to a mixing area where it is mixed with the carrier fluid. The additive chamber is connected to a bulk source of additive liquid from which it can be refilled and to which surplus additive can be returned. Displacing fluid is removed from the displacing chamber via a return line connected to a venturi. Suction is created in the venturi line through return of a carrier fluid through the venturi. <IMAGE></p> |
