Patent ID: 7174772

Claim:
A leak testing control assembly for a leak testing system of a type that cooperates with a test part interface that is coupled with a test part, said leak testing control assembly comprising: a) a working fluid generator for applying a working fluid having a fluidic pressure to a test part; b) a flow controller assembly coupled to said working fluid generator, said flow controller assembly including a flow controller element for controlling the flow rate of said working fluid; c) a pressure level measuring element positioned relative to said test part for measuring said fluidic pressure; d) a control system coupled to said flow controller assembly and said pressure level measuring element; and, e) a user interface coupled to said control system for providing user interaction with the leak testing control assembly, wherein during operation said control system 1) facilitates application of said fluidic pressure at a selected relatively constant flow rate; and, 2) Interprets the value of said fluidic pressure, after said application of said fluidic pressure at said selected relatively constant flow rate, to determine whether said test part is free of leaks.
