Abstract (en)

[origin: EP0371763A2] The present invention relates to a method for operating an electromagnetic valve means comprising a valve plunger journalled within a valve body for movement under the influence of an electric current on a drive stroke from a valve closed position to a valve open position, which valve means controls the flow of fluid to a nozzle orifice in a non-contact fluid droplet applicator apparatus, notably an ink jet printer, which method is characterised in that it comprises intermittently applying a transient drive current to the valve means 2 which is insufficient to move the plunger 11 of the valve means 2 sufficiently on its drive stroke towards the valve open position to permit the flow of fluid through the valve means 2.
