Automation of track for measurement of water valves characteristics
Lekeš, Pavel ; Havlíková, Marie (referee) ; Šedivá, Soňa (advisor)
My diploma thesis describes upgrade of flowbench serving as test rig for regulation valves characteristic measurement. At the beggining, there is an introduction to the water regulation valves theory followed by current machine condition description. Next chapter defines needed improvements and at the end follows proposition of improvements and necessary component definition and final realization. Final chapter summarizes complete project.

Wireless thermostat
Králíček, Martin ; Viščor, Ivo (referee) ; Kincl, Zdeněk (advisor)
The Master’s thesis discusses wireless thermostat for a control boiler. In order to complete the project we have to design and realise the whole project with software design. The system contains two units, a master control and a measurement of regulation units. The project initially talks about regulation of heating systems for family houses and larger buildings like schools and stores for example. Next, the project describes the control and regulation units and their potential extension for effective and economical operation. Both units are equipped with microcontrollers, which these control each of function. The communication between both units is provided by wireless interface in free radio band ISM. There is a user interface for the master control unit’s regulation process. The measurement and regulation unit has only the possibility to switch between manual and automatic control for regulation of heating system.

Valvetrain of Compression-ignition Tractor Engine
Mikula, Vojtěch ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This bachelor thesis deals with the main types and parts of the valvetrain systems of four-stroke engines. In the first part of the thesis are presented the most widely used versions of valvetrains and their use in the tractor engines. In the next part of the thesis is performed the construction and stress calculation of the valvetrain according to proposed proportions.

Regulatory and safety features hydraulic circuit
Smyček, Ondřej ; Hloska, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor´s thesis is focused on safety and regulatory elements of hydraulics. The main objective is to deal with options which are offered today. The theoretical part is accompanied by a design of throttle valve in a shorted circuit for an exchanger, which is a part of the heat transfer station, type AQHS by the company Tenza, a.s. In this design, two calculating softwares are used and compared. The input data for the design are based on the already existing heat transfer station Dřevařská 31, 33.
