Beschreibung
Zusammenfassung:	The present invention refers to a piston/cylinder assembly for alternative compressor, wherein the piston performs a reciprocating movement inside the cylinder, wherein piston surface (1 ) and cylinder surface have a surface roughness parameter Rpk of less than about 60 nm and a surface roughness parameter Rvk of less than 100 nm; and said piston surface (1 ) receives a coating comprising at least a support layer 2 and at least a DLC layer (3). La présente invention se rapporte à un ensemble piston/cylindre pour un compresseur alternatif, le piston effectuant un mouvement alternatif à l'intérieur du cylindre, la surface de piston (1) et la surface de cylindre présentant un paramètre de rugosité de surface (Rpk) inférieur à environ 60 nm et un paramètre de rugosité de surface (Rvk) inférieur à 100 nm; et ladite surface de piston (1) recevant un revêtement comprenant au moins une couche de support (2) et au moins une couche de carbone sous forme de diamant amorphe (DLC, Diamond-Like Carbon) (3).
