Dosing device for a lubricant dispenser

摘要

Dosing device comprises outlet openings (4) connected to the axial bore (8) of a slider (7) via a displacement chambers which are hydraulically separated from each other by non-return valves. A forward lift of the slider decreases the volume of the displacement chambers and allows lubricant to flow from the outlet openings. A rearward lift of the slider increases the volume of the chambers and allows the lubricant to flow through the valves. Preferred Features: The forward lifting movement of the slider occurs against the force of a restoring spring (15). At least one of the displacement chambers is formed by a slide guide (6) in a housing (5) or step of the slider.
