Description

Ventilanordnung an dem Biemskolben eines hydraulischen Türschließers Gegenstand der Erfindung ist eine Ventilanordnung an dem Bremskolben eines Ilydraulischen Türschließers, die ein schnelles Hindurchfließen der Hemmflüssigkeit durch den Kolben bewirkt und dadurch ein leichtes öffnen der Tür gestattet.Valve arrangement on the Biems piston of a hydraulic door closer The invention relates to a valve arrangement on the brake piston of an Ilydraulic Door closer that allows the inhibiting fluid to flow rapidly through the piston causes and thereby allows easy opening of the door.

Die bisherige Form des Kolbenventils war ein Kugelventil, das jedoch wegen des geringen Durchflußquerschnittes bei schnellem öffnen der Tür zu wenig öl durchließ und so einen Widerstand hervorrief. Zwar hatte man versucht, durch Klappen- oder Plattenventile die Durch$ußö.ffnung zu vergrößern, ,jedoch wählte man auch hierbei, zu kleine Durchflußöffnungen, so daß kaum eine Verbesserung zu bemerken war.The previous form of the piston valve was a ball valve, however too little when the door is opened quickly due to the small flow cross-section let oil through and thus provoked resistance. Although one had tried to get through Flap or plate valves to enlarge the flow opening, however, chose one here too, throughflow openings that are too small, so that there is hardly any improvement notice was.

Die Erfindung sieht nun eine Einrichtung vor, welche die beschriebenen Mängel der bisherigen Ventile beseitigt, , und zwar besteht die Erfindung darin, daß der Boden des Bremskolbens in seiner Gesamtheit als Ventilplatte ausgebildet ist, die beim öffnen durch den Flüssigkeitsdruck zurückgedrückt wird, so daß sofort eine große Durchtrittsöffnung für die Hemmflüssigkeit entsteht.The invention now provides a device which the described Defects of the previous valves eliminated, namely the invention consists in that the bottom of the brake piston is designed in its entirety as a valve plate is, which is pushed back when opening by the liquid pressure, so that immediately a large passage opening for the inhibiting liquid is created.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigen: Abb. i einen Längsschnitt durch die Kolbenseite eines hydraulischen Türschließers mit dem Kolben und der geschlossenen Ventilplatte, Abb. a den gleichen Längsschnitt mit geöffneter Ventilplatte und Abb.3 einen Querschnitt mit dem Kolben und den Führungsstiften für die Ventilplatte in Ansicht.The drawing shows an exemplary embodiment of the subject matter of the invention shown, namely: Fig. i a longitudinal section through the piston side of a hydraulic door closer with the piston and the closed valve plate, Fig. a shows the same longitudinal section with the valve plate open and Fig. 3 shows a cross section with the piston and the guide pins for the valve plate in view.

In dem Zylinder i gleitet der Kolben 2 hin und her. Die Druckfläche bzw. der Boden des Kolbens 2 ist als bewegliche Ventilplatte 3 ausgebildet, welche beim Rückgang des Kolbens sich öffnet und so die Hemmflüssigkeit des- Türschließers hindurchgleiten läßt.The piston 2 slides back and forth in the cylinder i. The printing area or the bottom of the piston 2 is designed as a movable valve plate 3, which When the piston recedes, it opens and so does the locking fluid of the door closer can slide through.

Beim Schließen drückt die Hemmflüssigkeit die Ventilplatte 3 wieder fest an den Kolben, wobei dieser. durch den,- konischen Plattensitz vollständig abgedichtet wird, so daß die Flüssigkeit in bekannter Weise dann durch die Regelungskanäle tritt.When closing, the inhibiting liquid presses the valve plate 3 again firmly to the piston, this. through the, - conical insert seat completely is sealed so that the liquid is then in a known manner through the control channels occurs.

Zur Geradführung der Ventilplatte 3 sind mehrere Führungsstifte 4 vorgesehen, die in Angüssen 5 im Kolbeninnern gleiten.To guide the valve plate 3 in a straight line, several guide pins 4 are provided provided that slide in sprues 5 inside the piston.

Die Angüsse 6 im Kolbeninnern dienen zur Aufnahme der Kolbenstange.The sprues 6 inside the piston serve to hold the piston rod.
