Abstract
A diaphragm valve includes a valve body defining a passageway constructed to form a valve seat, and a diaphragm. A compressor moves the diaphragm between a closing position in which a flow of fluid through the passageway is barred as the diaphragm is caused by the compressor to seal the valve seat, and an open position in which at least part of a cross section of the passageway is bounded by the diaphragm to thereby enable a flow of fluid through the passageway substantially without narrowing the cross section of the passageway.
