摘要
The present invention is a bleeding air regulator control pneumatic circuit for supplying air to a leakage detection system for testing a device under test for leakage. The bleeding air regulator control pneumatic circuit includes an air supply source having an outlet port for supplying compressed air to the leakage detection system; an air relay having a first port in fluid communication with the outlet port of the air supply source and a second port in fluid communication with an inlet of the leakage detection system; a pressure regulator having an inlet port in fluid communication with and connected at a point between the outlet port of the air supply source and the first port of the air relay, and an outlet port in fluid communication with and connected to a third port of the air relay; a bleed valve having a first port in fluid communication with a fourth port of the air relay and a second bleed port; and a flow control valve positioned between and in fluid communication with the air relay and the bleed valve.
