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.

The invention relates to a venting device (01) for venting a casting chamber (11) by means of an evacuation device (12), wherein the venting device (01) has a base body (02) having an outflow channel (03) which is formed within the base body (02) and having an insertion portion (04) for being connected to the casting chamber (11) in a detachable and fluid-conducting manner and having a connection portion (05) for being connected to the evacuation device (12) in a detachable and fluid-conducting manner, wherein air can flow out through the outflow channel (03) when evacuating the casting chamber (11) and a filter unit (06) is disposed in the outflow channel (03). Furthermore, the invention relates to a casting device (10) comprising at least one casting chamber (11) having a casting chamber wall (13). Furthermore, the invention relates to a casting device (10) comprising at least one casting chamber (11) having a casting chamber wall (13), and to a vacuum-assisted pressure die casting system (100) having a casting device (10) and to a method for operating a vacuum-assisted pressure die casting system (100).
