Abstract
A fluid dispensing apparatus such as a spray dampener sprays fluid on the rollers of a printing press. The spray is regulated by an automatic controller which pulses the spray at time intervals related to the signal of a press speed sensor. Fluid pressure controls and orifice configuration controls are eliminated; fluid pressure and orifice size are fixed.
