Abstract: A progressive distributor device for a liquid medium, particularly a lubricant, operating with a recurrent working cycle, comprising a plurality of distributors each having a housing and at least three consecutively displaceable working pistons mounted in cylinders of each housing and extending in parallel, the distributors being juxtaposed and hydraulically connected to each other in a manner so that for the working cycle, a first working piston of a first one of the distributors controls a second working piston of a last one of the distributors, and a first working piston of the last distributor controls a second working piston of a next to the last one of the distributors, a second working of each of the distributors connected to control a third piston of another distributor, with the third piston controlling a fourth piston of its distributor.
