Patent ID: 8480055

Claim:
A solenoid arrangement, comprising: a pole tube which is defined axially by a pole core segment, a transition segment having a uniform wall thickness, and a tube segment, in which the transition segment has a lesser wall thickness than the tube segment; and an armature guided movably in the pole tube in a path of movement, the armature, on an end toward the pole core segment, having a bolster axially protruding from an end face, wherein a cylindrical countersunk feature is present in a bottom face, toward the armature, of the pole core segment, the cylindrical countersunk feature defining a countersunk space, wherein the bolster of the armature is configured to be received in the countersunk feature, wherein the pole core segment, beginning at the bottom face, has an annular-conical collar segment, which is adjoined by the transition segment, and wherein an axial measurement of the collar segment exceeds an axial measurement of the bolster, and wherein the bolster is completely spaced apart from the countersunk space for at least a portion of movement of the armature in the path of movement.
