A nozzle for delivering vaporized liquid material has a cylindrical housing with a central, cylindrical cavity having a fluid inlet and a fluid outlet. The nozzle also has a plunger inserted into the fluid outlet of the housing so that the plunger and the housing form a fluid path. The plunger is moveable between a first position and a second position. A plunger stop is attached to the housing at the fluid inlet. A spring retainer is attached to the plunger. At least one spring is disposed between the housing and spring retainer to urge the plunger towards the first position. A method includes the steps of biasing a plunger moveable relative to a housing, with a fluid passage defined by the housing and the plunger, towards a first position; and providing fluid pressure to the fluid passage to urge the plunger away from the first position.
