Abstract

A high pressure dosing apparatus includes a housing with a chamber for receiving material to be dispensed. A dispensing output is controlled by a control valve which operates in response to pressure within the chamber so that the outlet is opened only when the pressure within the chamber exceeds a given level. A pressure generating means for controlling pressure within the chamber includes a pressure operated piston having a piston rod extending into the chamber. A pair of stops are provided for limiting the movement of the piston in opposite directions.
