Abstract: The dosing device includes a plurality of sections successively connected in the direction of the flow of the lubricant namely a valveless head section with a central supply duct, distributing sections and a valveless end section. The housing of each distributing section has a chamber accommodating a reciprocating distributing slide valve. The chamber is closed with closures limiting the reciprocation of the slide valve and defining two metering-out end chambers. Each chamber communicates with the reduced-diameter area of the distributing valve of the preceding section. The housing of each distributing section has central duct perpendicular to the axis of the cylindrical chamber, and outlet ducts. The inlets of the outlet ducts communicate with the cylindrical chamber, while the outlets of these ducts to feed the lubricant to the friction couples.
