ABSTRACT:
A dosing device for viscous materials, especially for paints, has a dosing cylinder, in which is disposed a dosing piston coupled with a hydraulically chargeable piston cylinder drive. A multi-way valve is placed ahead of the dosing cylinder to which is connected, on the one hand, a line for the supply of the material and, on the other hand, a pressure line for extrusion of the metered material by a drive, via a dispensing valve. The lines can be connected to the dosing cylinder selectively. The apparatus is embodied as a mobile unit. An open storage container is provided, from which originates the line for the supply of the material to the dosing cylinder which is embodied as a suction line. The drive is operatively arranged to effect the suction operation of the dosing piston.
