Abstract
A piston compressor includes a crankcase (), a crankshaft (), connecting rods (), a crosshead () with an arranged piston rod () and a piston (), dry-running guided in a cylinder (). Valves () are provided. A piston rod sealing device (), around the piston rod between the cylinder () and the crankcase, includes a gland device (), arranged in a gland housing (), inserted into a piston compressor housing (). The gland device includes a gland jacket () pushed into a gland () limiting, with the piston rod, a sealing gap (), which is open over a common longitudinal section, has a width in the μm range and allows a leakage flow () of the compressed medium therethrough. The gland and the gland jacket are formed of different materials with a resulting coefficient of thermal expansion essentially the same as the material of the piston rod.
