Abstract

Es wird eine automatische Pumpe offenbart, die nicht nur richtungsunabhängig installiert, sondern auch auf einfache und leichte Weise hergestellt werden kann. Bei der automatischen Pumpe kann nicht nur die Ventilbaugruppe lösbar mit dem Pumpengehäuse verbunden werden, sondern es kann auch eine Winkelposition der Ventilbaugruppe eingestellt werden, so daß die automatische Pumpe richtungsunabhängig installiert werden kann. Außerdem kann der Reed-Schalter auf der Unterlage befestigt werden, indem beide Enden des Reed-Schalters mit den Leiterbildern auf der Unterlage verschweißt werden, nachdem ein mittlerer Abschnitt des Reed-Schalters in dem Leerraum angeordnet wurde, der in einem mittleren Abschnitt der Unterlage ausgebildet ist. Damit ist die manuelle Arbeit der Befestigung des Reed-Schalters an der Unterlage einfach und leicht. Darüber hinaus ist es nicht erforderlich, eine externe Kraft auf den Reed-Schalter auszuüben, wenn der Reed-Schalter auf der Unterlage befestigt wird. Damit entfällt die Gefahr einer Beschädigung des Reed-Schalters.
