Balloon catheter apparatus for internal combustion engine component leak detection and high pressure leak detection

A universal inlet adapter for a leak detection device using a pressurized detection media for detecting a leak in a fluid system having a fluid duct, the universal inlet adapter comprising:

• an inflatable bladder having:
• a pair of opposed annular end walls disposed about a first axis, each end wall having an annular outer surface defining a terminal end of the inflatable bladder;
• a tubular wall coupled to the pair of opposed end walls and disposed about the first axis, the tubular wall and the pair of opposed end walls being arranged such that the pair of opposed end walls extend inwardly from the tubular wall toward the first axis;
• and
• an internal reservoir selectively transitional between an inflated configuration and a deflated configuration, a volume of the internal reservoir increasing as the inflatable bladder transitions from the deflated configuration to the inflated configuration;
• a test fluid delivery tube extending through the inflatable bladder such that a portion of the inflatable bladder is disposed radially outward from the test fluid delivery tube, the test fluid delivery tube being fluidly connectable with the leak detection device for delivering the pressurized detection media into the fluid duct for testing;
• and
• a pair of end caps coupled to the inflatable bladder, each end cap having an annular channel extending around the first axis to receive a respective one of the pair of opposed annular end walls including at least a portion of the annular outer surface of the corresponding annular end wall;
• the test fluid delivery tube and at least one of the pair of end caps being sized and structured to enable translatable movement of the at least one of the pair of end caps relative to the test fluid delivery tube so that a distance between the pair of end caps is adjustable to adjust a configuration of the inflatable bladder.
