The core 17 has an external thread with the knapsack syringe consists of a large pitch, through which, for example, in the case of a 45 ° container 1, on which a diaphragm pump 9 is attached to the side, an axial pivoting of the lever 10 is built, which is generated by a displacement of 15 to 20 mm, which can be actuated by a hand lever 10. With the is, an air chamber T is located in the liquid container 1

A valve 5 enables the entry of air 45, which is supported by the core 17 and into the interior of the liquid container 1 by means of a spring ring 26. The suction is axially fixed. Through a grease nipple 22, tube 11 of the diaphragm pump 9 extends into a recess

In Fig. 3 ist die Ventilmembran 13 als einzelner Bauteil in Ansicht gezeigt, bei der die lippenförmigen Teilenach entgegengesetzten Seiten gerichtet sind.provided, namely with a pressure valve 14, which points into the interior of the air chamber, and a suction valve 12, which shows into the interior of the chamber space 32. In Fig. 3, the valve membrane 13 is shown as a single one Component shown in view with the lip-shaped parts facing opposite sides.
Wird der Handhebel 10 bewegt, so gleitet der Kern 17 in dem auf dem Gehäuse feststehenden Teil des Gewindes 19 und schiebt z. B. den Bolzen31 in das Innere des Kammerraumes 32 vor. Dabei legt sich die ballige Scheibe 28 gegen die Pumpenmembran 27, so daß die Membran 27 voll abgestützt wird. Durch die im Kammerraum 32 unter Druck gesetzte Pflanzenschutzflüssigkeit wird das lippenförmige Saugventil 12 zusammengedrückt und geschlossen, während das Druckventil 14 geöffnet wird und das Pflanzenschutzmittel in den Windkessel T unter Druck eintritt. Bei dem Zurückschwenken des Handhebels 10 wird der Kern 17 zurückgezogen, und die kleinere ballige Scheibe 29 legt sich an die Pumpenmembran an. Dabei wird der Kammerraum 32 vergrößert, so daß durch das Rohr 11 neues Pflanzenschutzmittel in diesen eintritt. Durch den Druck im Windkessel 7' wird das lippenförmige Druckventil 14 zusammengedrückt und geschlossen gehalten. If the hand lever 10 is moved, the core 17 slides in the fixed part of the thread 19 on the housing and pushes z. B. the bolt 31 in the interior of the chamber space 32 before. The spherical disk 28 lies against the pump diaphragm 27 so that the diaphragm 27 is fully supported. The lip-shaped suction valve 12 is compressed and closed by the plant protection liquid placed under pressure in the chamber space 32, while the pressure valve 14 is opened and the plant protection agent enters the air chamber T under pressure. When the hand lever 10 is pivoted back, the core 17 is withdrawn and the smaller spherical disk 29 rests against the pump membrane. In the process, the chamber space 32 is enlarged so that new pesticides enter it through the pipe 11. The lip-shaped pressure valve 14 is compressed and kept closed by the pressure in the air chamber 7 '.
Bei einer Weiterbildung der erfindungsgemäßen Ausführungsform sind zwei derartige Pumpen vorgesehen, und zwar je eine an jeder Seite. Im Zusammenwirken mit einer feststehenden Sprühvorrichtung, die z. B. an der Rückseite des Pflanzenschutzmittelbehälters oder am Gürtel der Bedienungsperson angebracht sein kann, läßt sich durch die gleichzeitige Betätigung beider Pumpen ein höherer Druck erzielen. Wird dagegen ein bewegliches Sprührohr verwendet, so gestattet die Anordnung von zwei Pumpen ein ununterbrochenes Arbeiten unabhängig von der Wind- und Marschrichtung. Es genügt, das Rohr in die Windrichtung zu halten und den an der entgegengesetzten Seite liegenden Hebel zu betätigen.In a further development of the embodiment according to the invention, two such pumps are provided, one on each side. In cooperation with a fixed spray device, the z. B. attached to the back of the crop protection agent container or on the operator's belt can be, a higher pressure can be achieved by actuating both pumps at the same time. If, on the other hand, a movable spray tube is used, the arrangement of two pumps allows an uninterrupted one Work regardless of the wind and direction of travel. It is enough to point the pipe in the direction of the wind hold and operate the lever on the opposite side.
