CRANKSHAFT

A crankshaft (1) for a refrigerant compressor, the crankshaft (1) at least comprising a cylindrical shaft element (2), a crankpin (3) for driving a compressor piston of the refrigerant compressor, andmeans for conveying lubricant from a lower end region (4), averted from the crankpin (3), of the shaft element (2) in the direction of the crankpin (3) in order to supply lubricant to movable parts of the refrigerant compressor, wherein at least one surface portion of a surface of the crankshaft (1) has at least one flow disrupter, which flow disruptor is, owing to its geometry and/or configuration, configured to break up vapor bubbles and/or gas bubbles in the lubricant flowing around the crankshaft (1) in an operational state of the refrigerant compressor. 本发明涉及一种用于制冷剂压缩机的曲轴(1)，该曲轴(1)至少包括：圆柱形的轴元件(2)；用于驱动制冷剂压缩机的压缩机活塞的曲轴颈(3)；以及用于从轴元件(2)的背离曲轴颈(3)的下端部区域(4)朝向曲轴颈(3)的方向输送润滑剂的装置，以便为制冷剂压缩机的活动部件供给润滑剂，其中，曲轴(1)的表面的至少一个表面部段具有至少一个扰流器，所述至少一个扰流器由于其几何结构和/或特性设置成，破坏在制冷剂压缩机的运行状态中环绕曲轴(1)流动的润滑剂中的汽泡和/或气泡。
