1. An inking device for printing machines, comprising an inking body, which is designed to be arranged so as to face the lateral surface of an anilox roller and forms an inking chamber that is open toward said anilox roller and has at least one inlet for introducing the ink into said inking chamber and at least one outlet for the exit of the ink from said inking chamber, further comprising control means adapted to vary a passage opening of said at least one outlet as a function of the pressure of the ink in said inking chamber, wherein said inking chamber has a longitudinal extension that is substantially parallel to an axis of said anilox roller, substantially at each one of longitudinal ends of said inking chamber at least one respective ink outlet being provided, equipped with said control means, said at least one ink inlet being arranged in an intermediate position along a longitudinal extension of said inking chamber, further comprising, at each ink outlet, a redirection wall that extends substantially parallel to the longitudinal extension of said inking chamber so as to force the flow of ink to travel along an entire length of said inking chamber.
