Beschreibung
Zusammenfassung:	A current-pressure transducer, in particular for a vacuum control in automotive vehicles, is developed with a chamber (11) which is provided with a connection (18) for supply vacuum, with a connection (19) for removal of control pressure, with an air inlet for outside pressure and with a membrane (12) as chamber wall. The membrane can be displaced by a plunger-type armature (5) of a plunger-type armature electromagnet (1-7). With the membrane there is controlled a double valve (13-17) which, depending on the position of the membrane (12), can produce a fluid-conducting connection to the supply vacuum or to the outside pressure until the control pressure in the chamber (11) corresponds to the force exerted by the plunger-type armature (5) on the membrane and, in particular, is proportional to it. For the end position of the slope of the pressure-current characteristic, an approximately annular air gap (6) between the plunger-type armature (5) and a core (3) of the electromagnet is developed eccentrically to the longitudinal axis of said magnet and is adjustable rotatably around the longitudinal axis. The plunger-type armature (5) is for this purpose swingably mounted around a swing point outside the center line.
