Abstract
A metering device for a lubricant dispenser has an inflow opening and at least two outflow openings for dividing up the amounts of lubricant being conveyed, and has a slide inserted into a housing of the metering device so as to move lengthwise, which slide has an axial bore on the inflow side. The outflow openings are connected to the axial bore of the slide on the inflow side by way of a displacement chamber, in each instance. The displacement chambers are hydraulically separated from one another by kickback valves. A forward stroke of the slide brings about a reduction in volume of the displacement chambers and flow of the lubricant out of the outflow openings. A backward stroke of the slide brings about an increase in volume of the displacement chambers and follow-up flow of the lubricant through the kickback valves.
