Abstract

A pressure regulating valve (10) includes a magnet coil (16) received in a coil body (18), an armature (26) movable relative to a pole piece (20) for actuating a valve closing member (36), and a magnetic circuit (48) containing a magnet yoke (50). The magnetic circuit (48) has a maximum of three components (20, 66; 26, 50) that together form magnetic transitions (72, 74) oriented in the axial direction.
