ABSTRACT:
An air driven diaphragm pump having an actuator valve for converting a source of compressed air into a reciprocating drive. The actuator valve includes a valve piston for alternately directing air to one side or the other of the pumps, a control rod fixed to the reciprocating elements of the pump and means for shifting the valve piston responsive to the position of the control rod. An axially spaced bifurcated inlet is employed to provide additional energy to the shifting of the valve piston. The valve piston also is arranged to cover vent ports as a mechanism for closing off all compressed air under stalled conditions of the pump.
