| 摘要 |
The invention relates to a device for the lubrication of the bearing (9) of a rotating mass (10) held on an eccentric collar (5) of a drive shaft (2), especially of a displacement element of a spiral displacement machine used as charge air compressor for internal combustion engines. In order on the one hand to ensure a reliable, continuous lubrication of the bearing and on the other, in the case of spiral displacement machines, to prevent, if possible, any impairment of the combustion of charge air occurring in the internal combustion engine due to lubricating oil escaping from the bearing, it is proposed to provide a lubricant bore (4) running in the longitudinal direction in the drive shaft (2) and, in the area of the eccentric collar (5), means for the metered feeding of the lubricant in very small amounts to the bearing (9). At the same time a lubricant feed pipe (3) fixed to the housing and protruding coaxially into the lubricant bore (4) may be provided, which has an oil delivery aperture (6) corresponding to a transverse bore (7) on the eccentric collar (5). <IMAGE>
