ABSTRACT:
A drive mechanism for controlling pump mechanisms for simultaneous delivery of two atomizer liquids in selectable ratio to a sprayer device comprising two pneumatically actuated piston-cylinder drive mechanisms (air motors comprising reversing valve) and two pumps driven by the piston rods of the air motors. The intake side of each of said pumps is connected to a delivery side which, in turn, is connected to the sprayer device. The piston rods of the air motors are mechanically connected to one another by an adjustable balance arm. Both air motor are respectively provided with two pilot valves that are mechanically actuatable by the motor piston to control the reversing valves of the air motors.
