The invention relates to a solenoid valve having a coil, a magnet core, an armature, a yoke tube, a pole piece and a valve housing. The sealing and connection between the pole piece and the coil and/or the pole piece and the valve housing is effected by means of respective clamp-cutting edge connections each having a nose-like projection.

Solenoid valve

A method of producing an electromagnetic coil comprises winding a length of electrically conductive wire about a non-conductive tubular body having electrically conductive pins embedded therein, coupling opposite ends of the wire to the respective pins, and embedding the pins more deeply in the body following the coupling of the opposite ends of the wire to such pins.

Method of producing an electromagnetic coil

The invention relates to a solenoid valve with a coil body, a magnet core, an armature with armature guide and a yoke. In a first variant there is provided between the yoke and the armature guide a pole tube which has first means for producing an electrical contact with the armature guide and second means for producing an electrical contact with the yoke. In a second variant the solenoid valve also has a fixing plate which is disposed on the side of the solenoid valve on which the armature guide projects out of the yoke, the armature guide projecting through the fixing plate. According to the invention, in this variant a contacting element which produces an electrical contact between the fixing plate and the armature guide is provided between the fixing plate and the armature guide.

Solenoid Valve

The invention relates to a fastening system comprising a nut and a counterpart, wherein for protection against torsion of the nut at least two fastening elements are provided which interengage as a projection and a depression. In order on the one hand to secure the nut against inadvertent loosening and on the other hand to facilitate simple manual operation in tightening and loosening, the nut is made from resilient material and is constructed integrally with one of the two fastening elements.
