A progressive distributor including three or more control pistons (SA to SD), each of which can be displaced in a respective housing bore (A to D) of a distributor housing (G). The pistons are pushed alternately into their two final positions in the corresponding housing bore (A to D) by a lubricant which is supplied under pressure via a housing inlet (E), whereby a specific quantity of the lubricant (VSA to VSD) is delivered by means of an outlet (A1 to A8) on a respective front face. The outlet leads from one of two annular grooves (R) of the housing bore (A to D) of the respective preceding control pistons (SA to SD). The control pistons (SA to SD) are controlled sequentially by the lubricant as a result of the two respective annular grooves (R) in such a way that the following control piston (SA to SD) can only be displaced by the lubricant if the piston displacement of the preceding control piston (SA to SD) has been fully or almost fully completed. |
