Abstract: An agricultural sprayer having a liquid supply conduit for directing selectively controllable pressurized liquid to a plurality of spray nozzle assemblies. Each nozzle assembly includes a nozzle body having a respective orifice member having an inwardly tapered conical section communicating with a smaller diameter discharge orifice. Each respective orifice member is made of a resilient and pressure responsive deformable material such that upon an increase in the pressure of the liquid supply said liquid flow passage and discharge orifice thereof can be altered to increase the rate through said orifice member and nozzle body by at least 75 percent and upon interruption of the supply of pressurized liquid to the orifice member the orifice member liquid flow passage and discharge orifice return to their original shape.
