Description

Die Erfindung betrifft ein Wegeventil in Kolbenlängsschieberaus­ führung und bezieht sich auf die Gebiete des Maschinenbaues, der Verfahrenstechnik, der Mikroelektronik sowie der chemischen Industrie. Die technischen Objekte, in denen die erfindungsge­ mäße Lösung verwertbar ist, sind Werkzeug- und Verpackungsma­ schinen, Automatisierungseinrichtungen und Montagesysteme.The invention relates to a directional control valve in longitudinal piston valves leadership and refers to the areas of mechanical engineering, the Process engineering, microelectronics and chemical Industry. The technical objects in which the fiction The appropriate solution is the tool and packaging dimensions machines, automation equipment and assembly systems.

Die bisher für technische Zwecke eingesetzten Wegeventile beste­ hen in ihren wesentlichen Bauteilen aus einer metallischen Ven­ tilbuchse und einem in ihr verschiebbaren Ventilkolben, der ebenfalls aus Metall hergestellt ist. Eine solche Anordnung ist in der Offenlegungsschrift DE 33 09 065 beschrieben.The best directional valves previously used for technical purposes in their essential components from a metallic Ven tilbuchse and a displaceable valve piston, the is also made of metal. Such an arrangement is in the published patent application DE 33 09 065.

Metallische Ventilkolben-Buchsenkombinationen besitzen vielerlei Nachteile. So entsteht ein erheblicher Fertigungsaufwand, um die Passung zwischen Ventilkolben und -buchse zu erreichen. Dennoch ist ein relativ großes Radialspiel von ≧0,005 mm unvermeidbar. Beim Wechseln von Ventilkolben oder -buchse ist ein Einschleifen des jeweiligen Bauteiles notwendig.Metallic valve piston and socket combinations have many things Disadvantage. This creates a significant manufacturing effort to the To achieve a fit between the valve piston and bushing. Yet a relatively large radial play of ≧ 0.005 mm is unavoidable. When changing valve pistons or bushings, grinding in is necessary of the respective component is necessary.

Nachteilig ist auch der für das Metallsystem erforderliche Ein­ satz von Schmiermitteln. Weiterhin ist es kaum möglich, die aus Metall gefertigten Wegeventile mit aggressiven Medien zu betrei­ ben. Auch hinsichtlich der notwendigen chemischen und elektri­ schen Neutralität der Bauteile, z. B. beim Einsatz ionisierender Gase, sind metallische Wegeventile nicht geeignet. Das relativ hohe Gewicht des Ventilkolbens führt zu einem erhöh­ ten Massenträgheitsmoment, was die Schaltfrequenz und damit das dynamische Verhalten des gesamten Steuersystems einschränkt. Beim Arbeiten mit hohen Temperaturen kann die thermische Ausdeh­ nung des Ventilkolbens zur erhöhten Reibung oder gar zur Bloc­ kierung führen. Die rechtwinklige Anordnung der Steuerkanäle am Ventilkolben erlaubt es nicht, bei Bedarf eine variable Durch­ flußcharakteristik zu garantieren.Another disadvantage is the A required for the metal system set of lubricants. Furthermore, it is hardly possible to get that out Metal manufactured directional valves with aggressive media ben. Also with regard to the necessary chemical and electrical the neutrality of the components, e.g. B. in use  ionizing gases, metallic directional valves are not suitable. The relatively high weight of the valve piston leads to an increase ten moment of inertia, what the switching frequency and thus that dynamic behavior of the entire control system. When working at high temperatures, the thermal expansion Valve piston for increased friction or even to block lead. The right-angled arrangement of the control channels on Valve piston does not allow a variable through if necessary to guarantee flow characteristics.

Der Erfindung liegt die Aufgabe zugrunde, Ventilbuchse und -kolben hinsichtlich ihrer Form in Verbindung mit ihrem Werkstoff konstruktiv so zu gestalten, daß eine Verbesserung der Ge­ brauchseigenschaften bei reduziertem Fertigungs- und Kostenauf­ wand gewährleistet ist.The invention is based, valve bushing and the task -pistons in terms of their shape in connection with their material constructively so that an improvement in Ge properties with reduced manufacturing and cost wall is guaranteed.

Die Aufgabe der Erfindung wird dadurch gelöst, daß die aus bis­ her metallischen Werkstoffen gefertigten Bauteile Ventilbuchse und Ventilkolben aus einem Nichtmetall bestehen. Zweckmäßig sind es Glas, Keramik oder Kunststoff. Erfindungsgemäß ist die Ven­ tilbuchse mit parallel angeordneten schlitzförmigen Steuerkanä­ len versehen, die vorteilhafterweise unter einem Winkel von 75° bis 90° zur Längsachse angeordnet sind, um auch eine gewünschte Variabilität der Durchflußcharakteristik zu gewährleisten. Zweckmäßige Ausgestaltungen der Steuerkanäle bestehen darin, diese einseitig oder an der Ober- und Unterseite der Ventilbuchse anzuordnen oder durch Buchsen- und Distanzringe als Ringnut auszubilden. Je nach Fertigungstechnologie kann die Grundfläche der Steuerkanäle eben oder rund sein.The object of the invention is achieved in that the up to her metallic materials manufactured components valve bushing and valve piston consist of a non-metal. Are expedient it glass, ceramic or plastic. According to the Ven tilbuchse with parallel slotted control channels len provided, which advantageously at an angle of 75 ° are arranged up to 90 ° to the longitudinal axis to also a desired To ensure variability of the flow characteristics. Appropriate configurations of the control channels consist in these on one side or on the top and bottom of the valve bushing to be arranged or by bushing and spacer rings as an annular groove to train. Depending on the manufacturing technology, the footprint of the control channels are flat or round.

Die Erfindung wird nachstehend an einem Ausführungsbeispiel näher erläutert. Die dazugehörige Zeichnung zeigt in Fig. 1 einen Längsschnitt des Wegeventils in Kolbenlängsschieberausfüh­ rung und in Fig. 2-4 eine Detaildarstellung der Steuerkanäle 2. Fig. 2 zeigt die Anordnung der Steuerkanäle 2 an der Ober- und Unterseite der Ventilbuchse 1. Fig. 3 veranschaulicht die ein­ seitige Lage der Steuerkanäle 2 in der Ventilbuchse 1.The invention is explained in more detail below using an exemplary embodiment. The accompanying drawing shows in Fig. 1 a longitudinal section of the directional control valve in piston longitudinal slide execution and in Fig. 2-4 a detailed view of the control channels 2nd Fig. 2 shows the arrangement of the control channels 2 at the top and bottom of valve socket 1. Fig. 3 illustrates a side position of the control channels 2 in the valve bush 1.

In Fig. 4 ist die Ausbildung der Steuerkanäle 2 als Ringnut mittels Buchsenringen 10 und Distanzringen 11 dargestellt.In FIG. 4, the design of the control channels 2 as an annular groove by means of connector rings 10 and spacer rings 11 is shown.

Die aus Glas bestehenden Bauteile Ventilbuchse 1 mit parallel, unter einem Winkel von 75° angeordneten schlitzförmigen Steuer­ kanälen 2 und Ventilkolben 3 mit einem stumpfwinklig ausgeführ­ ten Übergang der Steuerkante 4 zum Nutgrund befinden sich in einem Ventilgehäuse 5, in welchem Bohrungen 6 zur Aufnahme der Anschlüsse 7 zum Verbraucher bzw. zur Atmosphäre dienen. Der Ventilkolben 3 wird mit je einem lagegeregelten Proportional­ magnet 8 und 9 betätigt. Bei Verwendung von ölfreier Luft mit einer Temperatur von 200°C und einem Versorgungsdruck von 0,8 MPa, wobei die -90° Frequenz 200 Hz und die Überdeckung 0,1 mm betragen, wird eine Reibkraft zwischen Ventilbuchse 1 und Ven­ tilkolben 3 von 0,03 N gemessen. Ohne erfindungsgemäße Lösung gemäß Stand der Technik beträgt sie 0,3 N.The components made of glass valve sleeve 1 with parallel, at an angle of 75 ° arranged slot-shaped control channels 2 and valve piston 3 with an obtuse angle execution of the control edge 4 to the groove base are in a valve housing 5 , in which holes 6 for receiving the connections 7 serve the consumer or the atmosphere. The valve piston 3 is actuated with a position-controlled proportional magnet 8 and 9 . When using oil-free air with a temperature of 200 ° C and a supply pressure of 0.8 MPa, the -90 ° frequency 200 Hz and the overlap 0.1 mm, a frictional force between the valve bushing 1 and Ven tilkolben 3 of 0 , 03 N measured. Without the inventive solution according to the prior art, it is 0.3 N.
