  • Patent number: 7866796
    Abstract: A solenoid valve making use of certain materials which is capable of operation at high frequencies and which can be made as a compact unit. The plunger (1) is made from a material having a saturation flux density greater than 1.4 Tesla preferably more than 1.6 Tesla, a coercivity at less than 0.25 ampere per centimeter and a relative magnetic permeability in excess of 10.000; and the nozzle bore leading from the valve head chamber (14) to the nozzle orifice (12) has a length to diameter ratio of less than 8:1 preferably between 2:1 to 4:1 and the nozzle orifice (12) has a diameter substantially the same as that of the nozzle bore. The invention also relates to method for operating a drop on demand ink jet printer incorporating such a valve.
