Abstract

Appts for injecting a liquid in a container in controlled drop-by-drop manner, at any rate of flow or frequency and at controlled elevated pressures, comprises (a) a hollow cylinder divided into two chambers by a piston, the piston rod of which slides through the upper end of the upper chamber, supplied by a pipe connecting it to the vessel contg. the liquid to be injected, and (b) an enlarged part in the upper zone of lower chamber which becomes progressively smaller downwards until it again becomes tubular at its lower end, in the base of which is an outlet nozzle of calibrated bore.
