Abstract
Die vorliegende Erfindung betrifft einen Kolben für einen Kolbenverdichter für gasförmige Medien mit einem innerhalb eines Zylinders (12) hin- und herbewegbaren Pleuel (14), wobei das Pleuel (14) mit dem Kolben (10) verbunden ist und der Kolben (10) einen Ventilteller (16) mit mindestens einem Durchlaß (18) für das von der Kolbenunterseite anzusaugende gasförmige Medium und einen ringförmigen Kolbenkopf (20) aus Kunststoff aufweist, wobei der Kolbenkopf (20) an seiner Ringinnenseite einen geschlossenen Stützring (22) aus Metall oder einer Metallegierung aufweist, wobei die Ausdehnungskoeffizienten des Stützringmaterials und des Zylindermaterials ungefähr gleich sind. The invention relates to a piston for a piston compressor for gaseous media with a connecting rod (14) which can be moved back and forth within a cylinder (12), the connecting rod (14) being connected to the piston (10) and the piston (10) one Valve plate (16) with at least one passage (18) for the gaseous medium to be sucked in from the piston underside and an annular piston head (20) made of plastic, the piston head (20) having a closed support ring (22) made of metal or a metal alloy on the inside of the ring has, the coefficients of expansion of the support ring material and the cylinder material are approximately the same.
