Abstract
A liquid dispensing gun for repeatedly dispensing precisely metered quantities of liquid from a pressurized source. The gun comprises a hollow body having a valve chamber and a metering chamber connected thereto by a control orifice. An axially slidable valve spool in the valve chamber and a trigger operated actuating plunger serve to govern the reciprocation of a metering piston in the metering chamber and the admission and discharge of metered quantities of liquid to and from the metering chamber.
