Abstract (en)
[origin: EP2103813A1] The line (1, 1') associated with the hydraulic consumer (H) includes a dosing unit (D). This exploits hydraulic medium compressibility, to supply small, controlled doses of hydraulic fluid. The dosing unit includes two hydraulic valves (G1, G2, V1, V2). These are connected in series, in upstream and downstream positions, with a dead space (T), e.g. a sealed container (6) or a line section between them. Each valve can be switched between a leakage-free closed position and a through-flow position. They are switched between these positions in alternation, during dosing. An independent claim IS INCLUDED FOR the corresponding method of adjusting a solar panel or machine actuator (claimed).
