Weiterhin sind zwei Speiseanschlüsse 12a und 12b für die Speisekanäle 6a und 6b und ein Entlüftungsanschluss 13 für den gemeinsamen Entlüftungskanal 5 an der Unterseite des Druckmittelverteilers 2 vorgesehen. Daneben sind zwei weitere Pilotventilspeise-/entlüftungsanschlüsse 14a und 14b für die Pilotventilspeisekanäle 8a und 8b sowie die Pilotventilentlüftungskanäle 9a und 9b vorgesehen.According to Figure 3 are on the underside of the pressure medium distributor 2 Working connections 7a and 7b for the assigned multi-way valves 1 in two rows arranged. Furthermore, there are two feed connections 12a and 12b for the feed channels 6a and 6b and a ventilation connection 13 for the common ventilation channel 5 provided on the underside of the pressure medium distributor 2. There are also two more Pilot valve feed / bleed ports 14a and 14b for pilot valve feed channels 8a and 8b and the pilot valve ventilation channels 9a and 9b are provided.

Mittels der Konfigurationseinheit 4 ist eine Konfiguration des Druckmittelverteilers 2 wie in Figur 4 gezeigt möglich. Die mit dem Speisekanal 6a in Verbindung stehende Öffnung 15 ist hier verschlossen. Somit sind die Speisekanäle 6a und 6b voneinander abgegtrennt. Damit ist es möglich, einen unterschiedlichen Druck in beiden Speisekanälen 6a und 6b bereitzustellen. Der Speisekanal 6b wird vom Speiseanschluss 16 an der Konfigurationseinheit 4 über die Öffnung 19a versorgt. Der Speisekanal 6a wird vom Speiseanschluss 12b an der Unterseite des Druckmittelverteilers 2 versorgt. Alle Entlüftungskanäle 9a, 9b des Druckmittelverteilers 2 sind über korrespondierende Öffnungen 17a bis 17c durch die Konfigurationseinheit 4 kurzgeschlossen. Die übrigen Pilotventilspeisekanäle 8a und 8b sind ebenfalls kurzgeschlossen und werden über die Öffnungen 18a und 18b mit Druckmittel versorgt, die mit dem Speisekanal 6b neben der Öffnung 19 in Verbindung stehen.The configuration unit 4 is used to configure the pressure medium distributor 2 as shown in Figure 4 possible. The one connected to the feed channel 6a Opening 15 is closed here. Thus, the feed channels 6a and 6b are apart abgegtrennt. This makes it possible to have a different pressure in both Provide feed channels 6a and 6b. The feed channel 6b is from Supply connection 16 on the configuration unit 4 is supplied via the opening 19a. The Feed channel 6a is from the feed connector 12b at the bottom of the Pressure medium distributor 2 supplied. All ventilation channels 9a, 9b of the pressure medium distributor 2 are through corresponding openings 17a to 17c through the configuration unit 4 shorted. The remaining pilot valve feed channels 8a and 8b are also are short-circuited and are pressurized via the openings 18a and 18b supplied, which are connected to the feed channel 6b next to the opening 19.

Gemäß der Konfiguration nach Figur 5 ist der Druck in beiden Speisekanälen 6a und 6b derselbe, weil die Öffnungen 15 und 19a durch die Konfigurationseinheit 4 kurzgeschlossen sind. Zur Erreichung einer maximalen Druchflussrate werden beide Speisekanäle 6a und 6b über die Anschlüsse 12a und 12b am Druckmittelverteiler 2 mit Druckmittel versorgt. Um einen Druckabfall an den Pilotventilen 10a und 10b zu vermeiden erfolgt deren Versorgung separat über die Pilotventilspeisekanäle 8a und 8b mit einem normalen Druck, der über den Pilotventilspeiseanschluss 20a in die Konfigurationseinheit 4 oder dem Pilotventilspeiseanschluss 14a am Druckmittelverteiler.2 eingeleitet wird. Hierfür sind die Öffnungen 17b und 19b geschlossen. Die Abluft der Pilotventile 10a und 10b kann über den Pilotventilentlüftungsanshluss 14b des Druckmittelverteilers 2 oder dem Pilotventilentlüftungsanschluss 20 der Konfigurationseinheit 4 abgeführt werden.According to the configuration according to FIG. 5, the pressure in both feed channels 6a and 6b the same because the openings 15 and 19a through the configuration unit 4th are short-circuited. To achieve a maximum flow rate, both Feed channels 6a and 6b via the connections 12a and 12b on the pressure medium distributor 2 supplied with pressure medium. To a pressure drop across the pilot valves 10a and 10b Avoid supplying them separately via the pilot valve feed channels 8a and 8b with a normal pressure, which via the pilot valve feed connection 20a into the Configuration unit 4 or the pilot valve feed connection 14a on Pressure fluid distributor. 2 is initiated. For this purpose, the openings 17b and 19b closed. The exhaust air from the pilot valves 10a and 10b can be via the Pilot valve vent connection 14b of the pressure medium distributor 2 or the Pilot valve vent connection 20 of the configuration unit 4 are discharged.

Bei der in Figur 6 gezeigten Konfiguration ist die Öffnung 15 des Speisekanals 5a verschlossen. Damit sind die beiden Speisekanle 6a und 6b durch die Konfigurationseinheit 4 voneinander abgetrennt. Somit kann in beiden Speisekanälen 6a und 6b ein unterschiedlicher Druck bereitgestellt werden, beispielsweise unter 3,5 bar und über 7,5 bar. Der Speisekanal 6a wird über den Speiseanschluss 12b des Druckmittelverteilers 2 oder über den Speiseanschluss 16 der Konfigurationseinheit 4 versorgt. Die Öffnungen 17b und 19b sind ebenfalls geschlossen, so dass die Versorgung der Pilotventile 10a und 10b über den Pilotventilspeiseanschluss 14a am Druckmittelverteiler 2 erfolgen kann.In the configuration shown in Figure 6, the opening 15 of the feed channel 5a locked. So that the two feed channels 6a and 6b through Configuration unit 4 separated from each other. Thus, in both feed channels 6a and 6b a different pressure can be provided, for example below 3.5 bar and over 7.5 bar. The feed channel 6a is via the feed connection 12b of the Pressure medium distributor 2 or via the feed connection 16 of the configuration unit 4 provided. The openings 17b and 19b are also closed, so that the Supply of the pilot valves 10a and 10b via the pilot valve feed connection 14a on Pressure medium distributor 2 can take place.

Die Erfindung ist nicht begrenzt auf die vorstehend beschriebenen bevorzugten Konfigurationen, die lediglich als Beispiel weiterer Varianten dienen sollen. The invention is not limited to the preferred ones described above Configurations that are only intended to serve as examples of other variants.
