Abstract

A pump for pumping rapidly and precisely a predetermined volume of liquid, comprising a closed vessel, a supply conduit to said vessel, an inlet to said vessel, a closure for said inlet and means for admitting a compressed gas into said vessel for forcing the liquid content of the container to exit through the supply conduit, characterized in that said closed container has an upper portion and a separable lower portion of said upper portion, because the supply conduit extends through the upper portion and communicates with the end inlet thereof near the lower portion of the container, and an outlet end sufficiently higher than the inlet end to prevent liquid from leaving the container, said inlet being disposed in the upper portion of said container, and being intended said container to be completely submerged in a bath of the liquid that must be b omitted so that the predetermined quantity of liquid pumped will correspond to the volume of said container, and said portion of separable lower container being intended to be replaced with another of such lower portions having different volumes, so that the volume of the pumped liquid can be changed. Changing the lower portion of the container. (Machine-translation by Google Translate, not legally binding)
