Description

Ventillose Pumpe für Flüssigkeiten. Die Erfindung bezieht sich auf eine ventillose Pumpe für Flüssigkeiten aller Art, durch welche mit einem Förderkolben zwei unter gleichem oder verschiedenem Druck stehende Verbrauchstellen versorgt werden können.Valveless pump for liquids. The invention relates to a valveless pump for liquids of all kinds, through which with a delivery piston supplies two points of consumption under the same or different pressure can be.

Die Einrichtung besteht im wesentlichendarin, daß ein Förderkolben durch eine unrunde Scheibe vermittels eines schwingenden Hebels mit veränderlichem Maul derart bewegt -wird, daß er bei Umdrehung der Antriebswelle zwei Hübe macht, indes ein Steuerkolben durch ein auf der gleichen Antriebswelle sitzendes Exzenter nur eine Hubbewegung während einer Umdrehung macht.The device essentially consists in that a delivery piston by means of a non-circular disc by means of a swinging lever with variable The jaw is moved in such a way that it makes two strokes when the drive shaft rotates, meanwhile, a control piston by an eccentric seated on the same drive shaft only makes one stroke movement during one revolution.

Die Zeichnung veranschaulicht die Einrichtung im lotrechten Schnitt. Es bezeichnet i den Förderkolben, ä den Steuerkolben, durch den je nach seiner Stellung die Flüssigkeit einmal durch den Kanal 3 und einmal durch den Kanal 4 gedrückt werden kann. 5 bezeichnet die Saugleitung. Auf der Antriebswelle 6 sitzt der Doppelnocken 7, der durch den .schwingenden Hebel 8 den Förderkolben hin und her bewegt. Durch die verschraubbar mit dem Schwinghebel verbundene Stange g kann die Maulöffnung des Schwinghebels 8 und damit die Hubhöhe des Förderkolbens i verändert werden. Der Steuerkolben .2 wird durch ein ebenfalls auf der Antriebswelle sitzendes Exzenter io und durch den Hebel i i bewegt und macht gegenüber dem Förderkolben i die halbe Hubzahl. Durch die Vorrichtung- -wird sowohl Förderwie Steuerkolben z-vangläufig bewegt.The drawing illustrates the device in vertical section. It denotes i the delivery piston, ä the control piston, through which the liquid can be pressed once through channel 3 and once through channel 4, depending on its position. 5 denotes the suction line. The double cam 7 sits on the drive shaft 6 and moves the delivery piston back and forth through the swinging lever 8. By screwing the rod g connected to the rocker arm, the mouth opening of the rocker arm 8 and thus the stroke height of the delivery piston i can be changed. The control piston .2 is moved by an eccentric io, which is also seated on the drive shaft, and by the lever ii and makes half the number of strokes compared to the delivery piston i. Both the delivery and the control piston are moved in a z-axis by the device.
