Vorrichtung zum Auffüllen deä Iiuftpolstera im Windkessel einerDevice for filling up the air cushions in the air chamber of a
KolbenpumpePiston pump
Der Windkassel einer Kolbenpumpe erhält heute u.a. sein Luftpolster durch ein Schnüffelventil an der Saugseite der Pumpe. Durch dieses Schnüffelventil wird bekanntlich immer etwae Luft mit in die Saugleitung der Pumpe gerissen, um dann im Windkessel ein Polster zu bilden.The wind chamber of a piston pump today receives its air cushion, among other things, from a sniffer valve on the suction side of the pump. As is known, there is always some air through this sniffer valve with torn into the suction line of the pump, to then in the air chamber to form a cushion.
Diese Art, Luft in den Windkessel hineinzubringen, hat verschiedene Nachteile. Einmal kann das kleine Schnüffelventil sehr leicht verstopfen und zum andern kann die Pörderflüseigkeit empfindlich gegen Luftzusatz sein.There are several ways of bringing air into the air chamber Disadvantage. On the one hand, the small sniffer valve can become clogged very easily and, on the other hand, the pumping fluid can be sensitive to the addition of air.
Die vorliegende Erfindung bringt nun eine Vorrichtung zum Auffüllen des Luftpolsters im Windkessel einer Kolbenpumpe, die einmal unempfindlich gegen die Verstopfung eines Sehnüffelveiitils ist und zum andern die zu fördernde Flüssigkeit nicht durohs«1;zen kann.The present invention now provides an apparatus for filling up of the air cushion in the air chamber of a piston pump that once insensitive to the constipation of a Sehnüffelveiitils and on the other hand the liquid to be pumped is not durohs «1; zen can.
Der Erfindergedanke liegt darin, daß der Kolben einer Kolbenpumpe direkt oder indirekt einen Kolben oder z.B. auch eine Membrane einer Luftpumpe steuert, die ganz und gar für sich in Abhängigkeit der Kolbenpumpe Luft fördert, um den Windkessel hiermit aufzufüllen. Der Vorteil dieser Erfindung ist vor allen Dingen nooh, . daß man mit einer solchen Vorrichtung die Menge der zu förderndenThe idea behind the invention is that the piston of a piston pump directly or indirectly a piston or, for example, a membrane an air pump controls which is completely dependent on itself the piston pump delivers air in order to fill the air chamber with it. The advantage of this invention is above all nooh,. that one with such a device the amount of to be conveyed

Luft viel besser bestimmen kann als über ein Schnüffelventil. Die LuftZuteilung läßt sich, durch eine solche Vorrichtung nach der vorliegenden Erfindung auch sehr gut regeln, indem man nämlich z.B. bei Erreichung eines bestimmten Pegelstandes im Windkessel die Förderung der Luftpumpe in der bekannten Weise aussetzen läßt. In der beiliegenden Zeichnung ist eine Aueführungsform der Erfindung veranschaulicht. In dem Kolbenpumpenzylinder 1 mit dem Sauganschluß 2 und dem Druckanschluß 3 bewegt sich in der bekannten Weise der Pumpenkolben 4 mit seiner Kolbenstange 5. Die Förderflüssigkeit tritt bei E in bekannter Weise ein, passiert den Ventilteller 6 mit seinem Sitz 7, um durch den Sauganschluß 2 in bekannter Weise in den Zylinder 1 einzutreten, um diesen durch den Druckanschluß 3 über den Ventilteller 8 mit seinem Sitz 9 zu passieren, um in bekannter Weise durch das Druckrohr to in den Windkessel 11 zu gelangen. Die Förderflüssigkeit verläßt den Windkessel in bekannter Weise bei A. Am Kolbenpumpenzylinder 1 sitzt nun nach dem Erfindergedanken ein Luftpumpenzylinder 12 mit dem Kolben 13 und der Kolbenstange 14· Zur Anschauung ist eine Druckfeder 15 vorgesehen, die den Kolben 13beaufschlagen soll. Bei S wird durch den Kolben 13 über den Ventilteller. 16 Luft angesaugt, um diese in bekannter Wels« über die Leitung D und über den Ventilteller 17 zu verlassen, um so als Druckluft durch die Leitung 18 in den Windkessel 11 einzutreten. Der Pumpenkolben 4 würde in diesem Fall z.B. gegen die Kolbenstange 14 laufen, um im LuftpumpenzylinderCan determine air much better than with a sniffer valve. The air allocation can be adjusted by such a device of the present invention also regulate very well by namely E.g. when a certain level is reached in the air chamber, stop the air pump in the known manner leaves. In the accompanying drawing is one embodiment of the Invention illustrated. In the piston pump cylinder 1 with the suction port 2 and the pressure port 3 moves in the known manner of the pump piston 4 with its piston rod 5. The delivery fluid occurs at E in a known manner, passes the valve disk 6 with its seat 7 to enter the cylinder 1 through the suction port 2 in a known manner, around this through the pressure connection 3 via the valve disk 8 with his seat 9 to pass through in a known manner the pressure pipe to get into the air chamber 11. The liquid to be conveyed leaves the air chamber in the known manner at A. The piston pump cylinder 1 is now seated according to the inventor's idea an air pump cylinder 12 with the piston 13 and the piston rod 14 Piston 13 is intended to apply. At S, the piston 13 via the valve disc. 16 air sucked in to make this known Wels «via line D and valve disk 17, so as compressed air through line 18 into the air chamber 11 to enter. In this case, the pump piston 4 would run against the piston rod 14, for example, in order to move in the air pump cylinder
12 in bekannter Weise den Luftpumpvorgang vorzunehmen, wobei in diesem Falle z.B. die Druckfeder 15 den Sauggang des Kolbens12 make the air pumping process in a known manner, wherein in this case, for example, the compression spring 15 is the suction passage of the piston
13 übernimmt.13 takes over.
Es ist klar, daß man den Kolben 13 z.B. durch eine Membrane ersetzen kann, aber das Wesentliche an dieser Erfindung ist, daß die Luftsteuerung über eine separate Pumpe erfolgt, die unmittelbar vom Pumpenkolben 4 gesteuert wird.It is clear that the piston 13 can, for example, be through a diaphragm can replace, but the essence of this invention is that the air control takes place via a separate pump which is controlled directly by the pump piston 4.
