A piston-cylinder unit is detachably arranged on each valve unit for drawing in and measured discharging of the liquid. Each valve unit has a hydraulic connection element for detachable hydraulic connection to the distributor rail. The distributor rail has an elongate fluid supply line, a supply connection for the liquid being provided on an end of the distributor rail and dosing unit connections being distributed laterally along the length of the rail. Each of the dosing unit connections are detachably coupled to the hydraulic connection elements of the dosing units. The distributor rail is a replaceable part made of a preferably recyclable, injection-moldable plastic.
