Abstract
A solenoid including an armature movable in an armature room and a coil which can be flowed through by current. When it is flowed through by current the armature moves. The armature interacts with an armature bar. A path converter is provided between the armature and the armature bar.
Claims12
Solenoid comprising
- an armature movable in an armature room,
- a control cone in a bottom region of the armature room, the armature being movable in the control cone,
- a coil passing current to generate a magnetic field for moving the armature, and the armature acting on an armature bar,
- a path converter located between the armature and the armature bar, the path converter including at least one compressible spring, and
- a connection point of the at least one compressible spring and an end of the armature bar being arranged axially shifted at the end of the armature bar with the end of the armature bar and an end of the at least one compressible spring being spaced from each other so that a force of the at least one compressible spring is biased against the end of the armature bar,
- the path converter having a housing holding the at least one compressible spring and a cylindrical pocket receptacle, the end of the armature bar being located in said pocket receptacle, the pocket receptacle being concentrically mounted almost completely inside the at least one compressible spring for avoiding tilting of the armature bar.

Pressure control valve comprising
- a solenoid including an armature movable in an armature room and a coil passing current, the coil, when passing current, generating a magnetic field for moving the armature, and the armature acting on an armature bar,
- a path converter located between the armature and the armature bar, the path converter including at least one compressible spring,
- a connection point of the at least one compressible spring and an end of the armature bar being arranged axially shifted at the end of the armature bar with the end of the armature bar and an end of the at least one compressible spring being spaced from each other so that a force of the at least one compressible spring is biased against the end of the armature bar, and
- a valve connected with the solenoid, the armature bar carrying a sealing body which also closes a seal receiver, and a position of the armature controlling a position of the sealing body with respect to the seal receiver, and the armature bar acting on a second sealing body which closes a second seal receiver in a current-less condition of the solenoid,
- the path converter having a housing holding the at least one compressible spring and a cylindrical pocket receptacle, the end of the armature bar being located in said pocket receptacle, the pocket receptacle being concentrically mounted almost completely inside the at least one compressible spring for avoiding tilting of the armature bar.
