ABSTRACT:
The central lubricating system has a progressive distributor (3) and a pump connected to the pressure connection of the initial segment of the progressive distributor, in particular for the manual feeding of lubricant by a hand pump or a lubricating gun. In order to improve such a central lubricating system so that upon manual or equivalent feeding of the lubricant preselected or adjustable delivery quantities of the progressive distributor are obtained by controlled cycles there is provided a predosaging unit (1) which contains a piston (16) which is arranged in the cylindrical space (12), can be displaced between two end positions and is spring-loaded at one end (spring 19). The cylindrical space (12) is divided by the piston into two working chambers (17, 18) which are connected to each other by a closable lubricant changeover canal (26), one of which chambers (18) is connected with the pressure connection of the progressive distributor and with a feed line (22) while the other (17) is connected to a control segment (6) of the progressive distributor.
