Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand vorliegender Erfindung ist eine Luftpumpe, namentlich für Luft-Radreifen, welche vermöge ihrer eigenartigen Construction ein besseres und bequemeres Arbeiten gestattet als die bisher bekannten, dem gleichen Zwecke dienenden Apparate. Dieser Zweck ist, wie aus beiliegender Zeichnung, die in Fig. 1 einen Längsschnitt der zusammengeschobenen und in Fig. 2 eine Ansicht der ausgezogenen Pumpe darstellt, ersichtlich ist, dadurch erreicht worden, dafs zwei Pumpencylinder A auf einer gemeinsamen Kolbenstange B mit zwei Ventilkolben C arbeiten. Man hat dadurch beim Pumpen in jeder Hand einen Pumpencylinder und damit eine gute Handhabe, so dafs die sonst zu diesem Zwecke verwendeten Handgriffe etc. in Fortfall kommen.The subject of the present invention is an air pump, especially for pneumatic tires, which, by virtue of its peculiar construction, allows better and more comfortable work than the previously known apparatus serving the same purpose. This purpose is, as can be seen from the attached drawing that the collapsed and in Fig. 2 is shown in Fig. 1 is a longitudinal section, a view of the extended pump, been achieved by that two Pumpencylinder A on a common piston rod B with two valve piston C work. As a result, when pumping, you have a pump cylinder in each hand and thus good handling, so that the handles etc. otherwise used for this purpose are no longer necessary.

Der Vortheil gegenüber Pumpen mit doppeltwirkenden Kolben besteht aufser in der Einfachheit der Construction darin, dafs nur bei einer Bewegung Kraft ausgeübt zu werden braucht, während bei dem Rückgang keine Arbeit geleistet wird.The advantage over pumps with double-acting pistons consists in the simplicity The construction consists in the fact that force only needs to be exerted in one movement, while none in retreat Work is being done.
