Device and method for dosing fluid

摘要

A device and method for dosing fluid has a housing enclosing a lifting element and a primary drive hydraulically operable on the lifting element via a hydraulic chamber. The lifting element is disposed within a borehole with a leakage permitting fit. A fluid chamber in communication with the borehole contains a fluid to be dispensed in a dosed manner by controlled axial movement of the primary drive and lifting element.
