Abstract

A method and apparatus for pressure testing containers in peripheral cells in a rotating turret is disclosed in which high pressure air in tested containers is initially discharged into a low pressure reservoir down to a predetermined low pressure and the residual air at the low pressure then discharged to the atmosphere with little sound generation. Incoming containers to the testing apparatus are initially supplied with pressurized air at a low pressure from the low pressure air reservoir and then supplied with pressurized air from a high pressure air supply, preferably a high pressure air reservoir, to achieve the desired test pressure. The low pressure reservoir and the high pressure reservoir are incorporated in the rotating turret structure and are in communication with a closure cap for each cell by distribution means including a double-acting valve during selected portions of rotation of the turret.
