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.

A new Variant of the Technology Components of the Valve Body
Kouřil, Vít ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
Bachelor thesis compares two technology variants of production on the inner part recess of the valve body type S43. This is a closing forged valve for power. The work analyses and displays structural design of the slide. After presenting existing technology of inner recess new technology is described in the thesis. The comparison was made with respect to machinery companies Armaturka Vranová Lhota, Inc. Assessment of better technology is described in the technical-economic evaluation at the end of thesis.

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.

Unconventional design for internal combustion engines
Šenkýř, Miroslav ; Imriš, Pavel (referee) ; Šplíchal, Miroslav (advisor)
The work is focused on unconventional concepts for internal combustion engines, namely, internal combustion engines of unusual structures. These are the engines that have different shapes of combustion chamber, shapes of shafts and specific output from the conventional concepts. This paper describes an unconventional engines as the Wankel engine and the Nutating engine. The work explains the construction, operating principle, advantages and disadvantages. Due to the continuous improvement of structures of these engines they have the future prospects in the aviation industry.

Electrically adjusted safety valve for HFA liquids
Šuranský, Michal ; Tlustoš, Jiří (referee) ; Grepl, Robert (advisor)
The purpose of bachelor’s thesis is proposal and implementation of automation mechanism of electrically adjusted safety valve for HFA liquids and its tuning and testing based on provider’s requirements. Automation mechanism proposal includes suggestion of mechanical, electronical and software components of the device. As a result of thesis is via Simulink’s Real Time Toolbox operational prototype with adjustable position. The provider of the valve is firm ŽĎAZ a.s., from Žďár nad Sázavou.
