ABSTRACT:
A fluid jet marking apparatus comprises a housing (5) defining a chamber (6) for marking fluid. A plurality of outlet nozzles (8) allow ink to be ejected from the chamber and a corresponding plurality of closure elements (9) are selectively displaceable to open and close the nozzles. Springs (11) bias the elements to close the nozzles. A plurality of solenoids (14) are each connected to a respective closure element by means of a pulling element (12) slidable, under the action of the solenoid, in a respective tube (13,13') connecting the solenoid to the housing. A fluid supply (23) supplies fluid to the chamber and at least one liquid constituent part of the fluid is supplied to the chamber through the respective tubes (13') on which the solenoids are mounted.
