Patent ID: 8205857

Claim:
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 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 ).
