An air driven vibrator is attached to a robotic applicator for sealants and adhesives. When the plane of vibration is normal to the axis of the dispenser, the vibration will impart a rotary motion to the applicator. When the plane of vibration is parallel to the axis of the dispenser and normal to the direction of motion of the dispenser (such dispensers are usually robot mounted), a side-to-side or pendulum action is provided. When the dispense tip is provided with a static mixer to mix plural component materials, the vibrator will enhance the mixer's action.

Rotary vibrating applicator for viscous materials

A system for cleaning of piping system using turbulent flow is provided by providing an input of a fixed flow rate of compressed air and a fixed flow rate of cleaning fluid. The fixed fluid flow is provided by either using an electric pump which may be controlled to do so or by restricting the air outlet of an air operated pump such that only a given amount of fluid will be delivered regardless of the pressure of the system into which the fluid is being delivered.
