A device for the simultaneous quantitative regulated filling of liquid or soft plasticized substances, such as butter, margarine, pastes or the like, by means of nozzles into adjacently arranged containers with the assistance of at least one control element interchangeably switchable from filling to discharging and at least one dosing piston. The device is arranged in such a way that two adjacent nozzles arranged in tandem are assigned one control element and one dosing piston. A passageway in the transition region from the actual dosing device to the nozzles can be adjusted preferably by means of a regulating valve whose angle of rotation can be altered. This regulating valve provides for an especially delicately sensitive and precise distribution of the product stream onto the one or the other nozzle for the purpose of balancing the output volume.
