  • Piston rod for a piston compressor, and the piston compressor
    Patent number: 9869312
    Abstract: A piston rod for piston compressors, wherein the piston rod has a base body with one end facing the piston, one end away from the piston, and at least one cavity. The cavity is filled with a solid, whose specific thermal conductivity is greater than that of the base body. Furthermore, the invention concerns a piston compressor with a piston and a nonlubricated piston rod seal, wherein the piston is connected to the described piston rod.

  • Crosshead bearing
    Patent number: 9528545
    Abstract: A crosshead bearing is disclosed, in particular for stroke piston machines, including a bearing surface (1) that contains multiple oilways (2), each of which is connected through a rearward borehole (3) to a lubricant source. The goal of the invention is to lower the peak oil pressure at the central load positions (4a, 4b) of the crosshead bearing and thereby achieve an overall load increase. This is achieved according to the invention by having one oilway (2) at each of the opposing central load positions (4a, 4b) of the bearing surface (1) be designated as the main discharge oilway (5).
