A single-phase, liquid spray nozzle for subdividing a flowing liquid stream into discrete fluid drops and for issuing the drops in a spray pattern, said nozzle comprising: means responsive to the flowing liquid stream for issuing a continuously-swept liquid jet which oscillates continuously back and forth between first and second limits; and, a stressing chamber comprised of: inlet means for receiving said continuously-swept liquid jet; outlet means through which discrete liquid drops may continuously pass to the ambient environment; peripheral sidewalls extending between said inlet means and said outlet means; means comprised of a plurality of stressing elements located in said chamber at said outlet means for stressing said continuously-swept liquid jet thereby causing said jet to subdivide into discrete drops which continuously issue from said stressing chamber through said outlet means in a continuously-swept pattern of drops rather than a jet; and, wherein said chamber has a first and second walls extending between said peripheral sidewalls and said plurality of stressing elements extend only part way from said first wall toward said second wall.
