Abstract
The paper presents the hardware and software structure of a linear unit for pneumo-hydraulic positioning, developed by the authors. The unit features two identical cylinders, one pneumatic and one hydraulic, mounted in parallel. The speed control is achieved by the use of two check valves of original construction. Mathematical model, simulation results and experimental results are also provided.
