Device for metering at least two components (A, B) by means of one piston-pump unit for each component, which pump units can be pressurised with the aid of at least one pressurised component. The aim of the invention is to create a metering device by means of which "dead" spaces in the metering cylinders and hence also variations in the metering ratios caused by this are prevented in an effective manner. This object is achieved by the fact that each piston-pump unit (13, 14) consists of single-acting piston pumps (15, 16, 17, 18) cooperating in pairs, that the piston pumps in each pair cooperate with one another via a pivotable yoke (20, 21) or the like and that the yokes are coupled together for rotation in common but can be displaced relative to one another in the plane of the yoke (Fig. 1). <IMAGE>
