A liquid dispensing apparatus is adapted to accurately dispense known volumes of liquid onto the receiving surface a workpiece, and comprises a cartridge having a reservoir for containing an amount of liquid. The cartridge has an outlet of known cross sectional area, and a piston adapted for longitudinal translational movement. There is a driving means for effecting movement of the piston, control means for operating said driving means, and means having a threaded portion for mechanically interconnecting the piston and driving means, so as to drive the piston within the cartridge. One of a first and second retaining means is securely connected to the piston and the other of said first and secondretaining means is securely connected to said cartridge, and the interconnectionmeans is longitudinally rigid between the first and said second retaining means so as to preclude unwanted relative movement of the piston with respect to the cartridge. Thus, when the piston is advanced along the cartridge towards the outlet, a known volume of liquid is dispensed. There is a feedback loop whereby the rate of liquid dispensing from the reservoir is substantially proportional to the rate of change in displacement of the outlet with respect to the workpiece, and varies proportionally as the rate of change in displacement varies.
