摘要： An auto-drain unit for a compressed gas supply system, comprising: a first, main chamber (24) including a liquid collection reservoir (27); a second, reference chamber (25); a discharge valve (35) actuatable to discharge collected liquid from the liquid collection reservoir (27); a trigger mechanism (37) for actuating the discharge valve (35); a diaphragm (23) at least in part defining the liquid collection reservoir (27) and the reference chamber (25), the diaphragm (23) being configured to be movable under the weight of liquid collected in the liquid collection reservoir (27) and operate trigger mechanism (37) when the weight of collected liquid exceeds a predetermined threshold; and a fluid conduit (41) fluidly connecting the reference chamber (25) to a location in the main chamber (24) above the maximum possible liquid level therein.
