Abstract

Die Erfindung bezieht sich auf einen Hohlkolben (1) für eine Kolbenmaschine, mit einem geschlossenen Ringhohlraum (9), bestehend aus einem ersten Kolbenteil (1a) mit einem Basisabschnitt (3), von dem sich in der einen axialen Richtung ein Gelenkteil (4) und in der anderen axialen Richtung jeweils einstückig eine den Ringhohlraum (9) außen begrenzende Umfangswand (6) und ein den Ringhohlraum (9) innen begrenzender Dorn (7) erstrecken, und bestehend aus einem zweiten Kolbenteil (1b) mit einem Deckel (8), der mit den dem Basisabschnitt (3) abgewandten Enden der Umfangswand (6) und des Dorns (7) verbunden ist. Zwecks Erzielung einer preisgünstigen, einfachen Herstellung bei Gewährleistung einer stabilen Bauweise sind die Umfangswand (6) und der Dorn (7) am Basisabschnitt (3) spanlos angeformt.
