Systems and methods for the injection/dispensing of fluid material in a volumetrically accurate and repeatable manner via an injection cell that interconnects two reservoirs of the fluid material. The injection cell has a normally closed dispensing valve that is opened for dispensing of the fluid material during a compression cycle, and closed during a return cycle. Opening and closing of the dispensing valve is effected using either or both of pressurized air and/or a motorized linkage. During the compression cycle, independent longitudinal displacements of a piston cylinder and a piston within the injection cell act to first open the dispensing valve and subsequently eject fluid material within the piston cylinder via the opened dispensing valve. The piston cylinder and piston are returned to an initial state that facilitates reloading of the injection cell from the reservoirs and closes the dispensing valve during a return cycle.
