Abstract: An electromagnetic valve assembly having upper and lower modules. A standardized lower module can be joined with one of several upper modules having a different axial length for varying the magnetic field strength of a coil arrangement in the upper module without changing the length or position of an armature tube in the lower module.

Abstract: An electromagnetic valve assembly having a valve unit with a valve seat and a coil arrangement. An armature is slidably disposed in the bore of the coil arrangement. A yoke unit surrounding the coil arrangement is in two parts having cooperating longitudinally extending edges forming two axially extending air gaps on diametrically opposite sides of the yoke unit. End flange portions of the two parts of the yoke unit are cut to form articulated tabs which facilitate the forming of the flange end portions.

Abstract: An electromagnetic valve assembly having a valve unit with a valve seat and a coil arrangement. An armature is slidably disposed in the bore of the coil arrangement and has one end cooperable with a core head to form an air gap and at the other end a closure device cooperable with the valve seat. The closure device has a ring shaped mounting part attached to the armature and a closure element in the form of a radially inwardly extending tongue-like part which is resiliently connected to the mounting part and is cooperable with the valve seat to maximize the operating effects of the coil arrangement.
