Abstract
A dosing system for filling containers with a particulate/liquid mixture includes three piston-and-cylinder devices, of which a first device delivers the mixture downwards to containers advanced beneath it, a second device feeds a thick particulate/liquid mixture via a conduit to the first device, and the third device feeds a thin liquid via a conduit to the first device. A liquid supply port is disposed peripherally in the cylinder of the first device and is swept by the piston thereof, and a conduit in continuous communication with the port extends through the piston to a lower axial end of the piston.
