ABSTRACT:
A pneumatic system is disclosed for regulating the acceleration and running speed of an air turbine and alternator used in electrostatic spray apparatus having a self-contained electrical power supply. The air turbine includes a rotor which is arranged to be biased in a first direction of rotation by a flow of impinging drive air and in a second opposite direction by a flow of impinging brake air. The flows of air cooperatively result in rotation of the turbine in a desired direction of operation and enable a minimized period of acceleration for a predetermined running speed.
