Course abstract

Study course explains foundations of machinery hydraulics and pneumatics. Studies introduce with major functional units' role, structure, operating principles and parameters, as well as framework and methodology of hydraulics design. Theoretical and practical learning of pneumatic braking systems, their management systems and regulatory capacities is provided.

Learning outcomes and their assessment


Knowledge: in hydraulic and pneumatic system operating principles and constructive architecture.
Skills: to evaluate hydraulic and pneumatic system, hydraulic and pneumatic control system and to organize the supply system. Maintenance and orientate in schematic map.
Competence: to choose and justify the operation in the proper technique of hydraulic or pneumatic system equipment and ensure the operation of hydraulic or pneumatic without any rejections; independently solve technical issues in a hydraulic or pneumatic supply system for operation.
