Abstract

A developing machine has a battery of vessels which receive metered quantities of liquid from discrete membrane-type pumping units. The pumping units constitute part of an apparatus having a single drive for the reciprocable membrane-deforming pumping elements of all units. The components of the drive for the pumping units as well as the pumping units themselves, are discrete modules which are rapidly connectable to or detachable from a single supporting frame. The drive has a rotary eccentric which transmits motion directly to the pumping elements of all pumping units. The strokes of the pumping elements are adjustable independently of each other.
