Abstract

The invention relates to a method for the metered, pulsed pumping of fluid media under high pressure, in which a pressure surge resulting from the stored, kinetic energy of an electromagnetically driven armature element of a reciprocating pump is transmitted via a blocking element to a working fluid, which is enclosed in a pressure space connected to a spraying device, resulting in a predetermined quantity of the working fluid being conveyed out of an spraying unit, the stored, kinetic energy of the armature element being abruptly transmitted first of all to an operating fluid, which is enclosed in a pressure-accumulating space arranged upstream of the pressure space, inducing a pressure surge which is transmitted in the operating fluid in an expanding manner to the blocking element and from the blocking element to the working fluid.
