ABSTRACT:
A machine for testing for air seal leaks in wheel rims which includes closure members for enclosing the inner chamber defined by the wheel hub and an outer casing which surrounds the closure members and into which a fluid is introduced under pressure. A liquid circuit is provided for initially filling the inner chamber with an incompressible liquid and a detection device communicates with the circuit to measure increases in pressures resulting from fluid leaking into the inner chamber during testing.
