Abstract
A vacuum suction force control apparatus is disclosed by way of a duct, having an entrance port and at least one exit port. Flow of suction force is controlled by moving a piston-like plunger inside the duct, connecting the entrance port to one, or simultaneously, multiple, adjacent exit ports. The present invention achieves known vacuum distribution without utilizing prior art electromechanical vacuum valves and associated electrical control cabling and power supply equipment. Therefore, the present invention is inherently capable of maintaining a particular, temporary distribution configuration without requiring electrical nor mechanical energy.
