Vorrichtung zum dosierten Zuführen von flüssigen oder viskosen Substanzen an eine Verbrauchsstelle

摘要

A device for supplying doses of a liquid or viscous substance, in particular a lubricant, to a point of consumption, has a transport device which supplies the substance contained in a reservoir to the point of consumption. The transport device has an energy accumulator which can be deformed against an elastic restoring force and which can be transferred by a moving device from a first position where the restoring force is low to a second position where the restoring force is high. The restoring force is then used in order to supply to the point of consumption an accurately defined volume of the substance contained in the reservoir. The volume conveyed per stroke and the number of conveying strokes per unit of time is controlled by an indicator which remains at the point of consumption when the device is replaced.
