Zusammenfassung:	An apparatus includes a valve body defining a chamber located on an axis. The chamber has axially upper and lower ends. The chamber farther has upper and lower orifices located at the upper and lower ends through which air can exit the chamber. An upper plug is configured, in a closed position, to close the upper orifice. A lower plug is configured, in a closed position, to close the lower orifice. A spring is compressed between the plugs so as to elastically urge the plugs axially apart and into their respective closed positions. A plug displacement device is configured to displace the upper plug from its closed position against bias of the spring into an open position, and to displace the lower plug from its closed position against the bias of the spring into an open position.
