Electromagnetic valve and safety-related pneumatic system
First Claim
1. An electromagnetic valve for safety-related pneumatic systems in motor vehicles, with an armature (9), which, by means of current supplied to an electrical winding (6), can be displaced axially relative to a core (13) and relative to a first valve seat (2), inside an inner channel of a coil carrier carrying the winding (6) on a winding section,wherein,in the armature (9) is arranged a guide channel, into which projects axially a guide pin (3) formed integrally with the coil carrier (1), so as to guide the armature (9) in the course of its axial displacement, and wherein the coil carrier (1) and the guide pin (3) have the form of a common injection-moulded plastic part, and wherein a radial guide clearance between the outer periphery of the guide pin (3) and the inner periphery of the armature (9) is smaller than a radial clearance between the outer periphery of the armature (9) and the inner periphery of the inner channel of the coil carrier (1).

Abstract
An electromagnetic valve for safety-related pneumatic systems in motor vehicles, with an armature (9), which, by means of current supplied to an electrical winding (6), can be displaced axially relative to a core (13) and relative to a first valve seat (2), inside an inner channel of a coil carrier carrying the winding (6) on a winding section, wherein, in the armature (9) is arranged a guide channel, into which projects axially a guide pin (3) formed integrally with the coil carrier (1), so as to guide the armature (9) in the course of its axial displacement.
