Abstract

Die Erfindung betrifft eine Kolbenmaschine, insbesondere Axialkolbenmaschine, mit einer Zylindertrommel (5), in der mehrere auf einem Umfang verteilt angeordnete Kolben (9) in Führungsbuchsen (8) verschiebbar geführt sind, wobei die Führungsbuchsen (8) mit ihren Kopfenden (8c) zuerst in Buchsenlöchern (6) in der Zylindertrommel (5) eingesetzt und befestigt sind, und wobei die Kolben (9) mit ihren Kopfenden (9a) Arbeitskammern (11) in der Zylindertrommel (5) begrenzen und mit ihren Fußenden (9b) an einem Triebteil der Kolbenmaschine (1) abgestützt sind. Um den Sitz der Führungsbuchsen (8) im montierten Zustand zu stabilisieren weisen die Innenmantelflächen (8b) der Führungsbuchsen (8) in den Endbereichen (a) ihrer Kopfenden (8c) jeweils eine Querschnittserweiterung (32) auf.

Figure 00000001
The invention relates to a piston machine, in particular an axial piston machine, with a cylinder drum (5) in which a plurality of pistons (9) distributed over a circumference are displaceably guided in guide bushes (8), the guide bushes (8) having their head ends (8c) first are inserted and fastened in bushing holes (6) in the cylinder drum (5), and the pistons (9) delimit working chambers (11) with their head ends (9a) in the cylinder drum (5) and with their foot ends (9b) on a drive part the piston engine (1) are supported. In order to stabilize the seat of the guide bushes (8) in the assembled state, the inner lateral surfaces (8b) of the guide bushes (8) each have a cross-sectional widening (32) in the end regions (a) of their head ends (8c).
