Abstract
Offenbart wird eine automatische Pumpe mit einer verbesserten Ventilkonstruktion, die einen Fluidkanal in einer Pumpe öffnen/schließen kann und gleichzeitig abhängig vom Vorhandensein eines Fluidstroms im Fluidkanal die Pumpe ein/ausschalten kann. Bei der automatischen Pumpe wird ein Ventil für die Verbindung/Trennung eines Einlaßrohrs und eines Auslaßrohrs zwangsweise in seine Ausgangslage zurückversetzt. Daher kann das Ventil in beliebiger Richtung angeordnet werden. Demzufolge gibt es keine Richtungseinschränkung beim Einbau der automatischen Pumpe. What is disclosed is an automatic pump with an improved valve design that can open / close a fluid channel in a pump and, at the same time, can switch the pump on / off depending on the presence of a fluid flow in the fluid channel. In the automatic pump, a valve for connecting / disconnecting an inlet pipe and an outlet pipe is forcibly returned to its original position. The valve can therefore be arranged in any direction. As a result, there is no directional restriction when installing the automatic pump.
