There is disclosed a central lubricating apparatus. It has a housing (2) with a row of piston pump units (6). Fig. 1 illustrates a prior art apparatus and Fig. 3 illustrates a new apparatus. It appears that the new apparatus is provided with one or more bearing liners (34) which via adjustable bolts (32) supports a rotatable shaft (18) upon which there is provided actuating cams (16) acting on a thrust pad (20) activating the piston (10) of the piston pump unit. As the thrust pad (20) and the actuating cams (16') are hardened, and as the shaft (18) is supported by the bearing liners (34), it is possible to utilise a known housing with very few modifications in order thereby to enable central lubrication via pressurised atomising nozzles having a pressure that may be about 10 times greater than traditional injection or pump pressure which is used and injected according to traditional principles. With the new centrallubricating apparatus it is thus possible to use pres- sure up to 100 bar or more, fat more than the performance of prior art lubricating apparatuses. |
