ABSTRACT:
A pneumatic valve bag packer provided with an air feed to the hopper that includes an eductor pump having its inlet connected to the hopper so as to produce a subatmospheric pressure in the hopper and consequent reverse air flow in the filling spout when the discharge of the eductor pump is open. The arrangement is such that the closure of the pump discharge by a valve provided for this purpose will result in superatmospheric pressure in the hopper suitable for bag filling. Abrupt opening of the pump discharge causes a vacuum pulse within as well as a sustained low pressure in the hopper so as to promptly stop and prevent material dribble from the filling spout.
