Abstract: A device for conveying viscous material out of a barrel-like container which has a container base and a container shell which extends upward from the container base, having a follower plate for closing off the container. The follower plate having a material outlet opening and a ventilation opening. There is a pump for conveying the viscous material through the material outlet opening, and a ventilation device for introducing compressed air through the ventilation opening, and a lowering device for lowering the follower plate in the container. A discharge valve is provided which, in a first switching position, blocks a line which leads out of the first pressure chamber, and which, in a second switching position, opens the line for the purposes of discharging pressure medium out of the first pressure chamber.
