PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Aufhänge- und Regelungsfeder, hauptsächlich für Rückschlagventile, zu dem Zweck, eine noch so geringe Saugwirkung benutzen zu können, für welche es unbedingt nöthig ist, das Eigengewicht des Ventils vollständig auszugleichen.The invention relates to a suspension and control spring, mainly for check valves, for the purpose of being able to use the smallest possible suction effect, for which it is absolutely necessary to use the own weight of the Compensate the valve completely.
Fig. ι zeigt ein Ventil mit der Aufhänge- und Regelungsfeder in Ansicht,Fig. Ι shows a valve with the suspension and control spring in view,
Fig. 2 im Schnitt undFig. 2 in section and
Fig. 3 die Aufhänge- und Regelungsfeder allein.3 shows the suspension and regulating spring alone.
Der Sitz e dient dem Zapfen c des Ventils d zur Führung. Auf dem Zapfen c des Ventils d sitzt die Feder, die das Ventil auf seinem Sitz hält. Die Feder ist so gewunden, dafs ihr oberer Theil α auf eine gewisse Länge von gleichem Durchmesser ist, um dem Ventilzapfen c, der mit Gewinde versehen ist, als Mutter zu dienen.The seat e is used to guide the pin c of the valve d. On the pin c of the valve d sits the spring that holds the valve on its seat. The spring is so wound that its upper part α is of the same diameter over a certain length, in order to serve as a nut for the valve pin c, which is provided with a thread.
Dieser Theil α der Feder dient zum Regeln der Federspannung, während der übrige Theil b zweckmäfsig kegelförmig gewundene Form hat und die eigentliche Feder bildet.This part α of the spring is used to regulate the spring tension, while the remaining part b is expediently conically wound in shape and forms the actual spring.
Durch Drehung der Feder auf dem Ventilzapfen läfst sich dieselbe nach Bedarf weiter vor- oder zurückschrauben und die Spannung der Feder und somit der Druck des Ventils auf seinen Sitz regeln. Besonderer Schrauben oder sonstiger Hülfsmittel bedarf es zu diesem Zweck nicht.By turning the spring on the valve pin, the same can be continued as required screw forwards or backwards and the tension of the spring and thus the pressure of the valve settle on his seat. Special screws or other aids are required for this Purpose not.
Die Federspannung wird so geregelt, dafs sie nur wenig höher ist, als nöthig, um das Ventil auf seinem Sitz zu halten. Selbstverständlich mufs das Ventil sich immer von oben nach unten öffnen, um gewissermafsen nur schwebend an der Feder aufgehängt zu sein.The spring tension is regulated in such a way that it is only a little higher than necessary for that Keep valve in its seat. Of course, the valve must always open from above open downwards so as to be suspended from the spring, so to speak.
Besonders ist ' hervorzuheben, dafs die Feder α b die beschriebene Ausbildung' besitzt, d. h. dafs sie zugleich die Feder- und Regelungswirkung gestattet und hauptsächlich zur Ausgleichung des Ventilgewichtes dient, um das Ventil schon bei der geringsten Saugwirkung sich öffnen zu lassen. Dabei ist die Reibung des Ventils durch die hängende Anordnung auf das kleinste Mafs gebracht.It should be particularly emphasized that the spring α b has the described design, ie that it simultaneously allows the spring and regulating effect and mainly serves to compensate for the valve weight in order to let the valve open even with the slightest suction. The friction of the valve is reduced to a minimum due to the hanging arrangement.
