A pressure regulation valve including a pilot stage valve with a ball valve body and a conical seat. A shock absorber with at least one pressure regulation valve.

Pilot stage with ball-conical seat

An electromagnetically actuated piston slide valve and an assembly set for such a valve with which an NC valve and an NO valve can be fabricated. Such a valve of the NC construction type comprises a valve housing with corresponding connectors and a fluid passage. A slide coupled with a magnetic armature is provided for regulating a free cross-sectional area of the fluid passage. A first spring urges the slide in an opening direction and a second spring urges the slide in an opposite closing direction, wherein the first and the second spring are adapted such that, in the electrically unenergized state of the coil, the slide adopts a position in which the fluid passage is closed.

Magnetic valve

A method for manufacturing a magnetic valve and a corresponding magnetic valve, in particular for the use for electrically continuously adjustable shock absorbers of a vehicle. A valve housing and a magnetic armature which is movably supported relative to a longitudinal axis of an electrically energizable coil and which is at least partially surrounded by a pole tube which is at least partially surrounded by a coil body of the coil that in turn is cast with a casting compound, provides a corrosion protection cap covering an axial end of the pole tube. The corrosion protection cap establishing a connection to the casting compound and protecting the axial end of the pole tube against corrosion influences from the atmosphere.

Magnetic valve and method for manufacturing a magnetic valve

An electromagnetically actuated piston slide valve includes a piston slide arrangement with a piston which is axially displaceable for regulating a free cross section of a fluid passage of the valve. The piston slide arrangement contains a first magnetic armature connected to the piston and a second magnetic armature which is axially displaceable with respect to the piston. The piston is axially displaceable against the force of a first biasing spring by generating an electromagnetic field through energizing a coil. A second biasing spring rests against the first magnetic armature and the second magnetic armature, so, in the unenergized state of the coil, the piston takes a predetermined position by axial displacement due to the force of the first biasing device against the force of the first biasing device. A permanent magnet generates an attractive force between the first and the second magnetic armature which counteracts the second biasing spring.

Piston slide valve

The invention relates to a method for manufacturing a pole tube, with two magnetic pole tube parts, for an electromagnet, in particular for a magnetic valve of an automatic transmission in an automobile, including the following steps: (a) arranging the pole tube parts on a centering arbor; and (b), connecting, in particular insert molding and/or casting an outer lateral surface of the pole tube parts; wherein the centering arbor has a radially expandable cylinder surface also closed even in the expanded state. Further, the invention relates to, in particular with the method obtainable, a pole tube, an electromagnet for a magnetic valve, in particular for an automatic transmission in an automobile, having a pole tube according to the invention, and an apparatus for the manufacture of the pole tube.
