Abstract
The present invention features a system to generate vacuum for picking up and holding a component in a component placement machine wherein the arrangement of the elements comprising the system prevents the flow of foreign matter back through the system. One arrangement locates a venturi between a valve and nozzle, thereby minimizing where vacuum exists within the system.
