Abstract
Elektromagnetisch betätigtes Ventil (10) für hydraulische Bremsanlagen von Kraftfahrzeugen, mit einem Polkern (24) und mit einem Magnetanker (15), deren einander zugewandte Stirnflächen (25, 26) an einem der beiden Bauteile mit einer Profilierung versehen sind, die in Form von wenigstens annähernd strahlenförmig verlaufenden Rippen (33) ausgebildet ist, dadurch gekennzeichnet, dass die Rippen (33) eine konvex gekrümmte Oberfläche haben.Electromagnetically operated valve (10) for hydraulic brake systems of motor vehicles, with a pole core (24) and with a magnet armature (15), the facing end faces (25, 26) of which on one of the two components are provided with a profile in the form of at least approximately radiating ribs (33) is formed, characterized in that the ribs (33) have a convexly curved surface.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem elektromagnetisch betätigten Ventil nach der Gattung des Patentanspruchs 1. Ein derartiges Ventil ist beispielsweise bekannt aus der
Bekannt aus der
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Ventil mit den Merkmalen des Patentanspruchs 1 hat demgegenüber den Vorteil, dass Rippen an der Stirnseite von Polkern oder Magnetanker eine konvex gekrümmte Oberfläche haben.The valve according to the invention with the features of claim 1 has the advantage that ribs on the front side of Polkern or armature have a convex curved surface.
Ausgehend vom Stand der Technik gemäß der
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Patentanspruch 1 angegebenen Ventils möglich.The measures listed in the dependent claims advantageous refinements and improvements of the patent claim 1 valve are possible.
Zweckmäßige Formen für die Gestalt der Rippen sind im Anspruch 2 angegeben.Appropriate forms for the shape of the ribs are given in claim 2.
Die im Anspruch 3 gekennzeichnete Maßnahme begünstigt einerseits die Fluidströmung zwischen dem Polkern und dem Magnetanker; andererseits sparen die Rippen einen Raum aus, in den eine Rückstellfeder des Ventils eingreifen kann oder der von einem Stößel des Ventils durchgriffen wird.The measure characterized in claim 3 on the one hand favors the fluid flow between the pole core and the armature; On the other hand, the ribs save a space in which a return spring of the valve can engage or which is penetrated by a plunger of the valve.
Ein kostengünstiges Fertigungsverfahren zum Herstellen der Profilierung ist im Anspruch 4 angegeben. Hierdurch wird neben der Erzeugung der Raumform auch eine Verfestigung des umgeformten Werkstoffs erzielt, so dass eine plastische Verformung der Rippen beim Schalten des Ventils vermieden wird.An inexpensive manufacturing method for producing the profiling is specified in claim 4. In this way, in addition to the generation of the spatial form, a solidification of the formed material is achieved, so that a plastic deformation of the ribs during switching of the valve is avoided.
