Abstract
A jetting device includes: a fluid chamber connected to a nozzle and containing an electrically conductive liquid to be jetted out through the nozzle; a magnetic field generator arranged to create a magnetic field in the fluid chamber; a pair of electrodes contacting the electrically conductive liquid in the fluid chamber; and a controller arranged to control a flow of an electric current through the electrodes and the electrically conductive liquid. The magnetic field generator is arranged to create a rotating magnetic field in the fluid chamber.
Claims5
A method of removing gas bubbles from a fluid chamber of a jetting device, the device comprising:
- a fluid chamber connected to a nozzle and containing an electrically conductive liquid to be jetted-out through the nozzle;
- a magnetic field generator arranged to create a magnetic field in the fluid chamber;
- a pair of electrodes contacting the electrically conductive liquid in the fluid chamber;
- and
- a controller arranged to control a flow of an electric current through the electrodes and the electrically conductive liquid,
- wherein the magnetic field generator includes at least one electromagnet, and
- wherein the magnetic field generator comprises a first magnet assembly arranged to create a magnetic field in a first direction normal to an axis of the nozzle, and a second magnet assembly arranged to create a magnetic field in a second direction normal to the axis of the nozzle and normal to said first direction, and the controller is arranged to modulate the magnetic fields created by the first and second magnet assemblies,
- the method comprising the step of controlling the magnetic field generator to rotate the magnetic field in the fluid chamber.
