Description

Rundlaufpumpe als Ladepumpe für Verbrennungskraftmaschinen. Das Zusatzpatent 408146 bildet eine weitere Neuerung zum Hauptpatent 36o863, die darin besteht, daß die Kolben durch eine Scheibe, die mit den entsprechenden Aussparungen für die Kolbenköpfe a der Kolben a1 versehen ist, bewegt werden, woben die Kolbenköpfe in Aussparungen der Kugeldruckscheibe beweglich eingelassen sind und das Laufen derselben bewirken.Rotary pump as a charge pump for internal combustion engines. The additional patent 408146 is another innovation to the main patent 36o863, which is that the pistons through a washer with the corresponding recesses for the piston heads a the piston a1 is provided, are moved, the piston heads in recesses the ball thrust washer are movably embedded and cause the same to run.

Es hat sich herausgestellt, daB die Scheibe e mit ihren Aussparungen, die unter Federdruck steht, ein einwandfreies Arbeiten der Pumpe reicht ermöglicht, da ein genaues Anpassen der Aussparungen in der Scheibe zum Kugelkopf infolge der verschiedenartigen Geschwindigkeiten und Bewegungen nicht möglich ist. Zu diesem Zweck wird nach vorliegender Erfindung der Kugelkopf des Kolbens mit einem Gleitschuh derart versehen, daß der Gelenkstern sich frei bewegen kann und ein einwandfreies Arbeiten der Kolben beim Umlauf der Trommel erzielt wird.It has been found that the disc e with its recesses, which is under spring pressure, allows the pump to work properly, because a precise adjustment of the recesses in the disc to Ball head is not possible due to the different speeds and movements. For this purpose, according to the present invention, the ball head of the piston with a Sliding shoe provided in such a way that the joint star can move freely and a flawless one Working of the pistons is achieved when the drum rotates.

In der Zeichnung ist in Abb. i ein Querschnitt der Neuerung, in Abb. z und Abb. 3 ist der Gleitschuh als Einzelheit dargestellt.In the drawing, Fig. I shows a cross-section of the innovation, in Fig. z and Fig. 3 the sliding shoe is shown as a detail.

Im wesentlichen besteht die Neuerung darin, daß, wie eingangs erwähnt, der Kugelkopf a der Kolben al mit dem Gleitschuh b versehen wird, wobei der Gleitschuh b in seinen Enden c nach erfolgter Montage auf dem Kugelkopf gegen evtl. Herunterfallen gesichert wird. Die Sicherung kann darin bestehen, daß die Kanten c nach innen gedrückt werden, so daß der Gleitschuh auf dem Kugelkopf derart beweglich befestigt wird, daß er trotz seiner Beweglichkeit nicht herunterfallen kann. Der Gleitschuh .ist ferner so ausgebildet, daß die Fläche d auf der Gelenkscheibe e frei aufliegt, d. h., -daß der Gelenkstern e keine starre Verbindung mit dem Gleitschuh b besitzt.Essentially, the innovation is that, as mentioned at the beginning, the ball head a of the piston al is provided with the sliding shoe b, the sliding shoe b in its ends c after installation on the ball head to prevent it from falling down is secured. The fuse can consist in that the edges c pressed inwards so that the sliding shoe is attached so movably on the ball head, that despite his mobility he cannot fall down. The sliding shoe .is also designed so that the surface d rests freely on the joint disk e, d. h., -that the joint star e has no rigid connection with the sliding shoe b.

Die Einrichtung kann an allen rotierenden Pumpen und Maschinen, die mit achsialen Kolben versehen sind, angebracht werden.The device can be used on all rotating pumps and machines that are provided with axial pistons.
