Description

Wechselventil für Entlastung des Pumpenkolbens bei der Druckperiode einer einfach wirkenden Pumpe. Wenn bei gewöhnlichen, einfach wirkenden Handpumpen der Kolbendurchmesser und der zu überwindende Druck ein bestimmtes Maß überschreitet, so reicht die Kraft eines Menschen nicht aus, den in seiner Länge beschränkten Pumpenhebel bei der Druckperiode der Pumpe nach unten zu drücken. Um nun den von unten gegen den Kolben wirkenden Druck zu mindern, ist die bekannte Differentialpumpe entstanden. Bei dieser wird der Druck unter den Kolben durch einen fast gleich großen Gegendruck auf den Kolben aufgehoben, der Kolben also dem Gleichgewichtszustand nahe gebracht; so ist es möglich, den Kolben ohne größeren Kraftaufwand mit verhältnismäßig kurzem Hand-Nebel nach unten zu bewegen.Shuttle valve for relieving the pump piston during the pressure period a single-acting pump. If with ordinary, single-acting hand pumps the piston diameter and the pressure to be overcome exceed a certain level, so the strength of a person is not sufficient, the pump lever, which is limited in its length to push down at the pressure period of the pump. To now against the one from below To reduce the pressure acting on the piston, the well-known differential pump was created. In this case, the pressure under the piston is created by almost the same counterpressure lifted on the piston, the piston thus brought close to the state of equilibrium; so it is possible to use the piston relatively briefly without great effort Hand moving fog down.

Da nun aber beim Aufwärtsgang des Kolbens, also bei der Saugeperiode der Pumpe, der auf dem Kolben lastende Wasserdruck wieder aufgehoben werden muß, ist ein mit dem Pumpenhebel zwangläufig verbundenes Getriebe nötig, welches den Wasserdruck auf den Kolben bei seinem Abwärtsgang selbsttätig anstellt, beim Aufwärtsgang des Kolbens den Druck wieder selbsttätig abstellt und gleichzeitig dem über dem Kolben befindlichenWasser den freien Abgang ermöglicht. Dieses Getriebe bildet den Gegenstand der Erfindung, der in der Zeichnung beispielsweise dargestellt ist, und zwar in Fig. i und 2 in zwei verschiedenen Kolbenstellungen.But now there is the upward movement of the piston, i.e. during the suction period the pump, the water pressure on the piston has to be released again, a gear necessarily connected to the pump lever is necessary, which the Automatically applies water pressure to the piston when it is going down, when it is going up of the piston turns off the pressure again automatically and at the same time that above the Piston located water allows the free drainage. This transmission forms the Subject of the invention, which is shown in the drawing, for example, and although in Fig. i and 2 in two different piston positions.

Die Vorrichtung besteht aus einem Ventilgehäuse a, in welchem zwei durch einen Schwinghebel b zwangläufig verbundene Ventilkegel c und d aufgehängt sind. Eingestellt werden die Kegel durch einen mit einem Gewichte beschwerten Hebel e. Der Hebel e wird durch zwei Mitnehmer f und g, welche auf einer Scheibe h sitzen, mitgenommen. Die Scheibe h erhält ihre Bewegung durch die Zugstange i von dem Pumpenhebel.The device consists of a valve housing a in which two valve cones c and d are suspended, which are positively connected by a rocker arm b. The cones are set by a lever e weighted down with a weight. The lever e is carried along by two drivers f and g, which sit on a disk h. The disk h receives its movement by the pull rod i from the pump lever.

Wird der Pumpenkolben, wie Fig. i zeigt, bei der Druckperiode der Pumpe nach unten bewegt, so gestattet der Ventilkegel c dem Wasserdruck die Entlastung des Pumpenkolbens. Während dieser Abwärtsbewegung des Kolbens sind die Mitnehmer f nach f und g nach g' gegangen und hat Mitnehmer f auf diesem Wege den Gewichtshebel e in die Stellung e' gehoben. Beim tiefsten Stand des Kolbens, also nach Beendigung der Druckperiode der Pumpe,- fällt der Hebel e aus der Lage e' in die Lage e" auf den Ventilkegel d und steuert die beiden Kegel mittels des Schwinghebels b (Fig. 2) um. Hierdurch wird das Druckwasser auf den Kolben abgestellt und der freie Austritt dem Wasser oberhalb des Kolbens bei der Saugeperiode der Pumpe gestattet. Während der Aufwärtsbewegung des Kolbens, also bei der Saugeperiode der Pumpe, sind die Mitnehmer f' nach f und g' nach g zurückgegangen und hat Mitnehmer g den Gewichtshebel e in die Stellung e"' gehoben. Beim höchsten Stand des Kolbens, also- nach Beendigung der Sauge Periode, fällt der Hebel e- aus der Lage e"' ' in die Lage e auf den Ventilkegel c und steuert die beiden Kegel mittels des Schwinghebels b wieder auf die Stellung nach rig. i um. @ Hierdurch wird das Druckwasser auf den Kolben für seine Entlastung bei der Druckperiode der Pumpe wieder angestellt `und gleichzeitig der Austritt des Druckwassers durch das jetzt geschlossene Ventil d wieder verhindert. Bei jedem Doppelhub vollzieht sich derselbe Vorgang.If the pump piston, as shown in FIG. I, is moved downwards during the pressure period of the pump, the valve cone c allows the water pressure to relieve the pump piston. During this downward movement of the piston, the drivers f went to f and g to g 'and in this way, driver f lifted the weight lever e into position e'. At the lowest level of the piston, i.e. after the end of the pressure period of the pump, the lever e falls from position e 'to position e " on valve cone d and controls the two cones by means of rocker arm b (Fig. 2) the pressurized water is placed on the piston and the free exit of the water above the piston during the suction period the pump allows. During the upward movement of the piston, ie, at the suction period the pump, the carriers are f 'to f and g' decreased by g, and has driver g lifted the weight lever e into position e "'. At the highest level of the piston, i.e. after the end of the suction period, the lever e falls from position e "" to position e onto valve cone c and controls the two cones again to the position according to rig by means of rocker arm b. i um. @ In this way the pressure water on the piston is switched on again for its relief during the pressure period of the pump and at the same time the discharge of the pressure water through the now closed valve d is again prevented. The same process takes place with each double stroke.
