Subject aims expressed by acquired skills and competences
The aim of the course is to acquaint students with the structure and function of pneumatic components and pneumatic systems. At the end of the course students should be able to design suitable linear pneumatic cylinder, rodless or semi-rotary motor, gripper or vacuum suction cup. They are also should be able to design and assemble a pneumatic circuit to control the working elements and to select the appropriate size of the elements for the correct operation of the mechanism.

Summary
Předmět je jedním ze základních pro obor Hydraulika a pneumatika a povinný pro státní zkoušku. Probírají se zde vlastnosti pneumatických mechanismů, vlastnosti stlačeného vzduchu, proudění, výtoková rychlost, výroba, úprava a rozvod stlačeného vzduchu, výpočet vedení. Dále jsou probírány pracovní prvky pneumatických mechanismů: pneumomotory přímočaré, kyvné, rotační, úchopné hlavice, jejich konstrukce a výpočty. Následují řídicí prvky: rozváděče, ventily jednosměrné, škrticí, logické, rychloodvětrávací, tlakové, jejich provedení, použití, vlastnosti a charakteristiky. Poté jsou probrány základní pneumatické obvody, jejich skladba a praktické sestavení na výukových trenažerech. V rámci předmětu jsou rovněž probrány vakuové mechanizmy, výpočty pneumatických obvodů a měření a zkoušení pneumatických prvků a systémů.
