The pump preferably comprises a constant displacement pump coupled to an electrical drive motor for drawing additive liquid from the reservoir and expelling it from the nozzle at a uniform rate of flow. The motor is connected electrically through a control unit to a rechargeable battery which is connected electrically to the output of a trickle charge transformer unit. The control unit includes an adjustable element disposed for preselecting the quantity of additive liquid to be injected into the wash load, and an electrical timer element energized from the battery for activating the motor a length of time corresponding to the quantity of additive liquid selected. The nozzle preferably is disposed adjacent an opening in the spin tub for directing therein the additive liquid expelled from the nozzle.
