Abstract: A piston is the driven component within a pump. The piston is driven along a longitudinal axis to pump a fluid through the pump. The fluid flows through the piston between an upstream end of the pump and a downstream end of the pump. The piston outputs the fluid into the downstream end of the pump at a vector offset from the longitudinal axis, thereby inducing rotation of the piston throughout the pumping process. Rotating the piston encourages even wear on various components within the pump, such as sealing rings surrounding the piston, thereby increasing the lifespan of the components and increasing the efficiency of the pump.

Abstract: A piston rod and piston head are the driven components within a pump. An upstream end of the piston rod is attached within an aperture of the piston head. At least one flute extends between the upstream end of the piston rod and the aperture, and the at least one flute is configured to provide a flowpath for a fluid, such as paint, to flow downstream of the piston head and piston rod. The flutes facilitate a smooth downstream flow of the fluid, thereby reducing hydraulic resistance and reducing wear caused by the fluid.

Abstract: A handheld sprayer comprises a housing, a turbine, a spray tip, a hopper and a trigger. An air flow passage extends through the housing. The turbine is configured to generate an airflow within the air flow passage. The spray tip is positioned to receive airflow from the air flow passage. The hopper is connected to the housing and is configured to discharge a fluid into the air flow passage. The trigger is mounted to the housing to control discharge of the hopper into the flow passage and airflow form the turbine. In different embodiments, the trigger controls airflow from the turbine to the spray tip or the hopper or both. Additionally, a method for spraying a fluid from a handheld sprayer comprises controlling airflow from a turbine and discharge from a hopper into a passage using a combined actuator.
