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 com
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.

1. A pressure regulating valve (10), having 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), characterized in that the magnetic circuit (48) h
1. A pressure regulating valve (10), having 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), characterized in that 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, wherein the magnetic circuit (48) includes at least one C-shaped magnet yoke (50) and one bushlike pole piece (20, 66), wherein the C-shaped magnet yoke (50) has a first yoke cheek (52) and a second, split yoke cheek (58), andwherein a first magnetic transition (72) oriented in the axial direction is embodied between the yoke cheek (52) and a first face end of the pole piece (20, 66), and a second magnetic transition (74) oriented in the axial direction is embodied between the second, split yoke cheek (58) and a second face end of the pole piece (20, 66). 2. The pressure regulating valve (10) as defined by claim 1, wherein the armature (26) is supported displaceably in the pole piece (20, 66). 3. The pressure regulating valve (10) as defined by claim 2, wherein the armature (26) is acted upon in the pole claim 2, wherein the armature (26) is acted upon in the pole piece (66) by a compression spring (68). 4. The pressure regulating valve (10) as defined by claim 1, wherein the second, split yoke cheek (58) engages the coil body (18). 5. The pressure regulating valve (10) as defined by claim 4, wherein the yoke cheeks (52, 58) of the C-shaped magnet yoke (50), in the state before assembly, form a bending angle <90° with one another relative to a yoke base (54). 6. The pressure regulating valve (10) as defined by claim 1, wherein the pole piece (20, 66), on its jacket face, has a recess (22) that is embodied in particular as a V-shaped groove and defines the location of a magnetic pole on the pole piece (20, 66). 7. The pressure regulating valve (10) as defined by claim 1, wherein the armature (26) has an end face (27) in which a aperture (76) that enables an exchange of media extends. 8. The pressure regulating valve (10) as defined by claim 1, wherein the magnet yoke (50) can be mounted on the coil body (18) in the transverse direction, is locked axially in the coil body (18) by one of the yoke cheeks (52, 58), and fixes a slide bearing (30) in the coil body (18), whose slide bearing guides (32, 34; 70) guide a bearing journal (38) of a valve closing member (36). 9. A pressure regulating valve (10), having 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), characterized in that 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, wherein the magnetic circuit (48) includes at least one C-shaped magnet yoke (50) and one bushlike pole piece (20, 66), wherein the C-shaped magnet yoke (50) has a first yoke cheek (52) and a second, split yoke cheek (58), and wherein the yoke cheeks (52, 58) of the C-shaped magnet yoke (50), in the state before assembly, form a bending angle <90° with one another relative to a yoke base (54).
