Document Type and Number:
Japanese Patent JP2660165
Kind Code:
B2
Abstract:
An apparatus 10 for testing seal integrity includes a test chamber 24 for receiving a sealed article 12 containing a tracer fluid, a reservoir chamber 44, and an analysis instrument 20 for detecting the presence of tracer fluid leaked from the article 12. A reservoir valve 64 in a conduit 58 coupled between the reservoir chamber 44 and the analysis instrument 20 has an open position for enabling a vacuum to be created in the reservoir chamber 44 using the analysis instrument 20. When closed, the reservoir valve 64 blocks fluid communication between the reservoir chamber 44 and the analysis instrument 20 to isolate the vacuum in the reservoir chamber 44. A valve 48 in a conduit 38 coupled between the test chamber 24 and the reservoir chamber 44 has a closed position for blocking fluid communication between the test chamber and the reservoir chamber. This prevents a pressure change in the test chamber 24 during creation of the vacuum in the reservoir chamber 44. The valve 48 has an open position for enabling the isolated vacuum in the evacuated reservoir chamber 44 to be applied to the article 12 in the test chamber 24 to draw the tracer fluid out of the article 12 through any leakage paths. The contents of the test chamber, including any leaked tracer fluid, are then conveyed to the analysis instrument.
