Abstract: A linear oscillating water jet is capable of spraying in a linear oscillating fashion without deviating from a consistent linear path such that a resulting linear spray does not extend beyond a targeted area. Through the use of an internal turbine, energy from an incoming pressurized liquid is used to create rotational motion, which is subsequently converted into an oscillatory, back and forth linear motion by way of a rocker assembly that connects a nozzle assembly to the internal turbine. The oscillatory, linear motion of the rocker assembly is translated into a linear, back and forth rocking motion for the nozzle assembly.
