Abstract of the Disclosure A valve actuator for a dosing pump for a paint toning machine, wherein the dosing pumps are mounted in a sled movable with respect to the frame of the machine and a dosing mechanism displacing the pistons of the dosing pumps and an actuator rotating the valves of the dosing pumps are mounted in the frame. The actuator comprises a crank mounted rotatably in the frame and two cam rods which are mounted pivotally in the frame and of which one is located in the path of movement of the crank and the other is provided with a transfer mechanism for transferring the cam rod optionally into and out of the path of movement of the crank. The cam rods are connected to a grap mounted rotatably in the frame so that the pivoting movement of one of the cam rods under the action of the crank causes rotation of the grap to a valve-closing position and the pivoting movement of the other cam rod under the action of the crank causes rotation of the grap to a valve-opening position. when rotating in one direction, the crank is in engagement with a crank-connecting rod means included in the dosing mechanism for dosing toner under the action of the movement of the crank of the valve actuator but is disengaged from the dosing mechanism when rotating in the other direction.
