Patent ID: 8641153

Claim:
A valve assembly which houses a valve-closing member that cooperates with an armature to connect or separate pressure medium channels in a valve housing, said valve-closing member being directed towards a valve seat which is arranged on a valve seat body fixed on the valve housing, a solenoid for actuating the armature, wherein said solenoid is contained within a yoke that is fitted onto the valve housing, a magnetic core which is inserted in the valve housing opposite the armature such that the armature is biased in a direction away from the magnetic core, a magnetizable tubular body including an aperture that at least partially defines the pressure medium channels, said magnetizable tubular body being separate from the valve housing and the valve seat body and mounted to both the valve housing and the valve seat body, said magnetizable tubular body defining an interior region in which either the magnetic core or the armature is at least partially positioned, and a non-magnetizable sleeve that is contained entirely within the yoke, said non-magnetizable sleeve defining an interior region in which the other of the magnetic core and the armature is at least partially positioned, wherein a top end of the non-magnetizable sleeve is positioned at an elevation beneath a top end of the solenoid, and a bottom end of the non-magnetizable sleeve is positioned at an elevation above a bottom end of the solenoid, a magnetizable closing plug that is mounted to the yoke to close one end of the valve assembly; wherein a top end of the sleeve at least partially overlaps the magnetizable closing plug in an axial direction, and the magnetizable closing plug is positioned adjacent a top end of the solenoid, wherein a bottom end of the sleeve at least partially overlaps the magnetizable tubular body in the axial direction, and the magnetizable tubular body is positioned adjacent a bottom end of the solenoid, and wherein different valve functions can be performed with the use of identical valve housing components in a modular manner.
