ABSTRACT:
The double-conduit central lubricating system has two feed conduits (I, II) which are supplied from a pump via a switch device which operates as a function of pressure difference and via a change-over valve, at least one double-conduit lubricant distributor being connected to said feed conduits. In order to improve such a system in such a manner that even an extremely different requirement for lubricant at individual rubbing points can be satisfied and that, for instance, lubrication requirements of individual friction points of a ratio of 1:100 can be satisfied precisely in a simple manner with a single lubrication cycle, a control chamber (9, 10) of a progressive distributor (11, 12) is connected to an outlet of the double-conduit lubricant distributor (3, 4, 5) via a control conduit (7, 8) the pressure inlet (13) of said progressive distributor in the initial segment being connected with both feed conduits (I, II). The control chamber (9, 10) of the progressive distributor (11, 12) has no direct connection (13) to the pressure connection of the initial segment.
