Patent attributes
An oscillating spray nozzle and related methods for providing spray patterns in a variety of oscillating patterns by driving movement of the nozzle with a progressing cavity displacement motor. By varying the design of the progressing cavity displacement motor, a variety of spray pattern geometries can be generated and a speed of the nozzle as it travels through the spray pattern geometries can be controlled. The oscillating spray nozzle can include a housing enclosing a progressing cavity motor that is operably connected to a spray nozzle. The progressing cavity motor includes a rotor member that is caused to rotate and oscillate within a stator member. The rotor member is operably linked to the spray nozzle, whereby the movement of the rotor member is communicated to the spray nozzle.
