Cecil Sundaram, Design of a four-stage air piston compressor. Ostrava: VSB Technical University of Ostrava, Faculty of Mechanical Engineering, Department of Power Engineering, 2019, 112p. Supervisor: Ing. Zdeněk Šmída. My master thesis is focused on the designing a four-stage air piston compressor by calculating the main dimension of the internal diameter with the given parameters. The paper is divided into two parts, theoretical and practical part. In the theoretical part, the paper focuses mainly on the piston compressors and its divisions with their main parts and the energy transformations which occurs in these machines and also the energy transformation machines which emphasise the volume compressors and their division. The task in the...
