Abstract
An electromagnetic pressure-regulating valve includes a housing comprising a first, a second and a third port, a valve seat, a valve closure member, an electromagnetic drive, and a biasing device. The electromagnetic drive comprises a coil wound on a coil carrier, an armature, a core, and an electromagnetic return-path device. The armature moves between a first and second end position and acts on the valve closure member. The biasing device is configured so that, when a current does not flow, the armature, and thereby the valve closure member, is positioned in a fail-safe setting on the valve seat so that a connection from the third port to each of the first and second ports is closed. The valve seat is connected via a fluid channel to the first and second ports. The armature is steplessly adjustable between the first and second end positions in every setting.
