Course detail

Fluid Power

FSI-MIM Acad. year: 2026/2027 Winter semester

The course provides students with basic knowledge in the field of fluid power – hydraulic and pneumatic mechanisms which are a part of many modern machines and equipment. It contains the basic theoretical knowledge, description of the most important hydraulic elements, hydraulic drives and introduction to the design of hydraulic circuits. In the field of pneumatic mechanisms, it presents the basics of theory, a description of basic elements, including their application and possibilities for compressed air production.
