Abstract
A liquid transfer system particularly suited for transferring a processing chemical between a reservoir and a tank in a photographic processing apparatus, comprises a liquid reservoir having an outlet which is connectable to the tank in the processing apparatus. The reservoir is connected to a source of pressurized gas which forces liquid to be transferred from the reservoir to the tank. The outlet of the reservoir is provided with a valve arrangement which serves to close the reservoir outlet when the liquid level in the reservoir drops below a predetermined level and prevents pressurized gas from escaping from the reservoir.
