Description

Beschreibung der Gebrauchsmusteranmeldung des Herrn Mathias Jacoty, Hetzerath-Mosel Bez. Trier, Bahnhofstrasse betreffend: Luftpumpen Saugventil für Pflanzenspritzen. Description of the utility model registration of Mr. Mathias Jacoty, Hetzerath-Mosel Bez. Trier, Bahnhofstrasse regarding: Air pump suction valve for sprayers.

Gegenstand der vorliegenden Gebrauchsmuster-Anmeldung ist eine Saugventilanordnung für Inftpumpen in Pflanzenspritzen.The subject of the present utility model application is a suction valve assembly for injection pumps in plant syringes.

Bei den bisher bekannten Luftpampen wurde teils aus Billigkeits= gründen, teils aus Platzmangel auf ein besonderes Saugventil verzichtet und die Kolbenmanschetto übernahm die Arbeit des Saugventils. In diesem Falle hebt sich die Manschette während des Saughubes etwas von der Zylinderwand ab und lässt die Ansaugluft vorbeistreichen. Dieser vorbeschriebenen Ausführung haften jedoch Mängel an, indem nur Manschetten aus dünnem Leder oder Gummi verwandt werden können und sich ferner die Manschette erst dann öffnet, wenn bereits ein grosser Teil des Kolbenhubes vor= über und ein entsprechendes Vakuum im Pumpenzylinder vorhanden ist. Somit ist bei dieser Anordnung erheblich mehr Kraftanstrengung erforderlich als bei meiner neuen Ventilanordnung und ausserdem ist die Wirtschaftlichkeit numehr bedeutend grösser.In the case of the previously known Luftpampen, partly for reasons of cheapness, partly due to lack of space on a special suction valve and the piston sleeve took over the work of the suction valve. In this case, the cuff is lifted during of the intake stroke away from the cylinder wall and lets the intake air sweep by. However, there are deficiencies in this design described above, in that only cuffs made of thin leather or rubber can be used and furthermore the cuff only opens when a large part of the piston stroke is already in front = over and in there is a corresponding vacuum in the pump cylinder. Thus, with this arrangement considerably more effort is required than with my new valve arrangement and the profitability is also significantly greater.

Die vorstehend geschilderten Nachteile sind durch Anordnung meines neuen Luftpumpen-Saugventils behoben. Bei ist vor allem der geringe Platzbedarf und die Billigkeit der Fertigung, sowie die sicherwirkende Arbeitsweise einer damit ausgerüsteten Luftpumpe.The disadvantages outlined above are mine by arrangement fixed new air pump suction valve. The main thing is that it takes up little space and the cheapness of production, as well as the safe working of one with it equipped air pump.

Der Erfindungsgegenstand ist auf beiliegender Zeichnung im Schnitt dargestellt. Dieses neuartige Luftpumpen Saugventil besteht aus dem Saugventilkörper-a-, der Ventilplatte-b den Ventillöcheern - h - und dem am Ventilkörperboden befinedlichen Zapfen mit Rille zum Halten der Ventilplatte-b-.The subject of the invention is shown in section on the accompanying drawing shown. This novel air pump suction valve consists of the suction valve body-a-, the valve plate-b the valve holes - h - and the one on the valve body base Pin with groove to hold valve plate-b-.

Der Saugventilkörper - a - wird mittelst Gewinde in die hohle Kolbenstange - c - eingeschraubt und hält damit gleichzeitig die beiden Kolbenscheiben - d - und - f -, wie auch die zwischen die Scheiben geklemmte Kolbenmanschette - g - fest. Während des Saughubes hebt sich die Ventilplatte-b-von dem Ventilkörper - a-ab und öffnet dadurch die Ventillöcher-h-. Infolgedessen kann die luft von aussen durch die hohle Kolbenstange-cdurch den Saugventilkörper - a - und durch die Ventillöcher-hin den, unter dem Kolben befindlichen Zylinderraum strömen.The suction valve body - a - is threaded into the hollow piston rod - c - screwed in and holds the two piston disks at the same time - d - and - f -, as well as the piston sleeve clamped between the discs - g - firmly. During the suction stroke, the valve plate -b-lifts off the valve body -a-and This opens the valve holes -h-. As a result, the air from the outside can pass through the hollow piston rod - c through the suction valve body - a - and through the valve holes flow through the cylinder space located under the piston.

Unmittelbar bei Kolbenumkehr schliesst das Ventil wieder luft - dicht ab für den nun folgenden Druckhub. Ich stelle folgende Schutzansprüche : 1). Luftpumpe Saugventil für Pflanzenspritzen, dadurch gekenn. zeichnet, dass der Saugventilkörper-a-an der Ventilseite eine kreisrunde ebene Ventilfläche mit einer Anzahl Ventillöcher-h-im Ventilboden hat. 2.) Eine Ausführungsart nach Anspruch l, dadurch gekennzeichnet, dass der Ventilkörper-a-am Ventilboden mit einem Zapfen mit Rille zur Aufnahme der Ventilplatte-b-ausgestattet ist. As soon as the piston is reversed, the valve closes again - close off for the pressure stroke that now follows. I make the following protection claims: 1). Air pump suction valve for plant sprayers, thereby marked. draws that the suction valve body-a-on the valve side a circular flat valve surface with a number Has valve holes-h-in the valve base. 2.) An embodiment according to claim l, characterized in that that the valve body-a-on the valve bottom with a pin Equipped with a groove to accommodate the valve plate-b- is.

3. )Luftpumpensaugventil für Pflanzenspritzen nach Anspruch 1 u. 2 weiter dadurch gekennzeichent, dass der Ventilkörper - a -mit Gewinde zum Einschrauben in die hohle Kolbenstange ausgestattet ist und gleichzeitig zum Befestigen der Kolben= teile auf der Kolbenstange dient.3.) Air pump suction valve for plant sprayers according to claim 1 and 2 further characterized in that the valve body - a - has a thread for screwing in into the hollow piston rod and at the same time to attach the piston = parts on the piston rod is used.
