Abstract
The invention relates to a spray dampening system in printing presses, comprising: a rotating roller (2); nozzles (3) facing the roller; a pressurized piping (11) for supplying water or other fluid to the nozzles; control valves (7), along with electrical actuators therefor, in association with each nozzle, said control valves including a closing and opening spindle (1). Said electrical actuators comprise: an adjustment rod (5) of some MSM material, having its first end in contact with the spindle (1) and its second end resting against a stationary base (10), a return element (12), as well as a coil assembly surrounding the adjustment rod for establishing a magnetic field (14) applied to the adjustment rod. The field intensity enables changing the adjustment rod length and setting a spindle position in the control valve for thus regulating the amount of water or fluid flowing through the nozzles (3) as a spray (8).
