VACUUM DISTRIBUTION CONTROLLER APPARATUS
Document Type and Number:
WIPO Patent Application WO2002077452
Kind Code:
A3
Abstract:
A vacuum suction force control apparatus (200) employs a duct (201), having an entrance port (205) and at least one exit port (P1, P2, P3, Pn). Flow of suction is controlled by moving a piston-like plunger (216) inside the duct (201), connecting the entrance port (205) to one, or simultaneously, multiple, adjacent exit ports (Pn). Vacuum distribution is achieved absent electromechanical vacuum valves and associated electrical cabling and power supply equipment.
