A pressure feeder for feeding solid or semi-solid material plastic in nature from a container into or through a relatively narrow outlet, comprising a container for the material with an outlet at the bottom thereof, a hollow cylindrical pusher member oval-shaped in cross-section and having a gear along the inner periphery thereof, a driven pinion gear mounted on the container and inserted in the pusher member, and a holder fixedly mounted on the container so as to hold the pusher member between it and the pinion gear. The pusher member carries out repeatedly a linear movement followed by a turn about the pinion gear. |
