Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die den Gegenstand vorliegender Erfindung bildende doppeltwirkende Pumpe kann als Tiefbrunnen-, Hochdruckpumpe, zum Betrieb von Gartenspritzen u. a. m. Verwendung finden.The subject of the present invention forming double-acting pump can be used as Deep well, high pressure pump, for operating garden sprayers and others. m. find use.

Die Pumpe unterscheidet sich von bekannten dadurch, dafs die Kolbenstange nicht durch die Wandung hindurchgeführt ist und daher in der Cylinderachse keine Stopfbüchse vorhanden ist; die Kolbenstange wird durch eine besondere, seitlich vom Cylinder liegende Stange angetrieben, mit welcher sie durch einen Mitnehmer starr verbunden ist. Hierdurch fällt das bei den jetzt gebräuchlichen Pumpen häufig vorkommende ungünstige Wirken, ja sogar Versagen fort, welches dadurch entstand, dafs bei Undichtwerden der an den Kolbenstangen vorgesehenen Stopfbüchsen Luft in den Cylinder drang, was die Saug- und Druckwirkung der Ventile beeinträchtigt. The pump differs from known pumps in that the piston rod does not pass through the wall is passed through and therefore there is no stuffing box in the cylinder axis is; the piston rod is secured by a special one on the side of the cylinder Driven rod, with which it is rigidly connected by a driver. Through this the unfavorable which frequently occurs with the pumps in use now falls Work, yes even failure, which resulted from the fact that the The stuffing boxes provided on the piston rods penetrated the cylinder, causing the The suction and pressure effect of the valves is impaired.

Auf der Zeichnung ist eine der vorliegenden Erfindung gemäfs eingerichtete Pumpe dargestellt. The drawing shows a pump set up according to the present invention.

Die Kolbenstange α der in den Cylindern b wirkenden Kolben c und d ist durch den Mitnehmer e mit der Stange f starr verbunden. Diese wird durch den am Gehäuse g der Pumpe passend gelagerten Hebel h angetrieben. Der Antrieb kann jedoch auch mit Kurbel, Excenter oder dergl. mit Hand- oder Kraftbetrieb erfolgen. Die Stange f ist bei ihrem Durchgange durch das Gehäuse g mittelst der Stopfbüchse i abgedichtet. Da diese aber abseits von den Cylindern b und den darin gleitenden Kolben c und d liegt, so kann ein Undichtwerden der Stopfbüchse nicht so leicht einen Einflufs auf die Wirkung der Kolbenventile k und / haben, als wenn die Stopfbüchse an der Kolbenstange a, also in der Cylinderachse, läge.The piston rod α of the pistons c and d acting in the cylinders b is rigidly connected to the rod f by the driver e. This is driven by the lever h suitably mounted on the housing g of the pump. The drive can, however, also take place with a crank, eccentric or the like, with manual or power operation. The rod f is sealed by means of the stuffing box i as it passes through the housing g. Since this is located away from the cylinders b and the pistons c and d sliding in them, a leak in the stuffing box cannot so easily have an influence on the action of the piston valves k and / than if the stuffing box is on the piston rod a, i.e. in the cylinder axis, would be.

Die sonstige Wirkungsweise der Pumpe weicht von der bekannten nicht ab. Der Antriebshebel h wird in der in der Zeichnung dargestellten Stellung in der Pfeilrichtung bewegt. Der Kolben d saugl aus dem Saugrohr m an, während der Kolben c die Flüssigkeit in das Druckrohr η befördert.The other mode of operation of the pump does not differ from the known one. The drive lever h is moved in the direction of the arrow in the position shown in the drawing. The piston d sucks in from the suction pipe m , while the piston c conveys the liquid into the pressure pipe η.
