Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine weitere Ausbildung der Stoßfangvorrichtung nach Patent 195213 und hat die besondere Gestaltung des Kolbens dieser Stoßfangvorrichtung zum Gegenstande.The invention relates to a further embodiment of the bumper device according to the patent 195213 and has the special design of the piston of this bumper device.

Dem Kolben des Patentes 195213 ist eine ballige Gestalt, vorzugsweise die Form einer ■ Kugel gegeben. Diese Kugel form hat besondere Vorteile, da die Kolbenstange auf Knickung bzw. Biegung beansprucht ist, wodurch ein Ecken des Kolbens eintreten kann. Bei dem Gegenstande der Erfindung, welcher durch die Fig. 1 bis 5 veranschaulicht wird, ist die Berührung zwischen Kolbenum-J5 fang und Zylinderwandung in noch größerem Maße wie bei der balligen Ausbildung des Kolbenumfanges auf eine Linie beschränkt, und zwar dadurch, daß der Kolben kegelförmig (Fig. ι und 2), doppelkegelförmig (F'g-3)' doppelkegelförmig geschweift (Fig. 4) oder halbballig (Fig. 5) ausgebildet ist, so daß die Reibung zwischen Kolben und Zylinderwand sowohl gegenüber der zylindrischen als auch der balligen Form des Kolbens verringert wird.The piston of the 195213 patent has a spherical shape, preferably the shape of a sphere. This spherical shape has particular advantages because the piston rod is subject to bending or bending, which can result in corners of the piston. The object of the invention which is illustrated by Figs. 1 to 5, the contact between Kolbenum- J 5 is caught and cylinder wall is limited to an even greater extent as in the convex form of the piston periphery to a line, namely the fact that the Piston is conical (Fig. Ι and 2), double conical (F'g-3) 'double conical curved (Fig. 4) or hemispherical (Fig. 5), so that the friction between piston and cylinder wall both against the cylindrical and the spherical shape of the piston is reduced.
