An actuator for a dosing pump, especially, for a paint toning machine, comprising a grab (11) displacing the piston (7) of the dosing pump (2) and a crank lever system for transferring the grab between two extreme positions in which the piston of the dosing pump is located in a position (I) corresponding to an empty pump and in a position corresponding to a full pump. The crank lever system comprises a crank (9) driven by a power element (14) and a connecting rod (10) provided with a grab, the crank being arranged to be located at its dead point with respect to the transfer movement of the grab at least when the grab is located in the extreme position (I) corresponding to an empty pump so that the wide range of movement (???) of the crank produces only a small transfer movement (H) of the grab. <IMAGE> |
