Class A audio power amplifier with tubes
Krutílek, David ; Brančík, Lubomír (referee) ; Kratochvíl, Tomáš (advisor)
The topic of my bachelor´s theis is of the class A audio power amplifier using vacuum tubes which is completed with phono preamplifier and input selector. There are used ECC 83 and ECC 88 vacuum tubes for the pre-amplifier design, then EM 84 tubes for the „eye-magic“ equalizer and 300B tubes for the power amplifier design. The maximum output power is 2 x 20W to 8 ? load. In this paper there are presented schematics of the pre-amplifier and power amplifier too. The aim of this bachelor´s project was make complete design of laboratory prototype (scheme, layout of printed circuit, part list and placemnet), realisation function of prototype and laboratory measurements.

Design of stand for atmospheric resistors testing
Kerek, Milan ; Hudec, Martin (referee) ; Houška, Pavel (advisor)
This master’s thesis deals with the design and manufacture of device for testing and verification of functionality of atmospheric resistors produced by IMI CCI Czech Republic. An atmospheric resistor, also called disk stack, is a stack of disks through which the medium flows and the system of labyrinths in disk stack causing a pressure reduction of medium. This thesis describe design of the mechanical parts of stand for atmospheric resistors, choice pneumatic circuit’s components, data acquisition hardware for measuring flow, inlet and outlet pressure, and temperature. The software was created in LabVIEW programming environment. In the end of this paper was done measurement in order to test functionality of test stand and software.

The grinding of valves
Stránský, Michal ; Bumbálek, Bohumil (referee) ; Osička, Karel (advisor)
This diploma thesis deals with grinding of parts of valves. In the first part is theoretically described valve and its manufacturing. Another part focuses on the analysis of existing grinding technology. In last part of this diploma thesis is written about choosing of suitable places for rationalization, design of rationalization and technical-economic evaluation of performed rationalization.

General Solution of Valvetrain Mechanical Losses
Mynařík, Aleš ; Maršálek, Ondřej (referee) ; Novotný, Pavel (advisor)
This master's thesis deals with the determination of mechanical losses in the valvetrain of the combustion engine. It describes the computational and experimental methods of determining the mechanical losses of valve mechanism. The practical part of the thesis focuses on the programing of structures in Matlab. This application calculates the values of mechanical losses of valvetrain and displays their graphical representation. This program is used for computing the mechanical losses of the selected real engine.

CFD simulation of refrigerant flow inside the semihermetic compressor
Tuhovčák, Ján ; Knotek, Stanislav (referee) ; Katolický, Jaroslav (advisor)
The CFD simulation of cooling piston compressor Stream, manufactured by Emerson company, is the topic of this diploma thesis. Analysis of moving parts (piston, valves) and refrigerant or physical settings for simulation were based on experimental data provided by Emerson. The goal of the thesis is to test opportunities of Star-CCM+ in simulating the flow inside the compressor. In the end there will be a comparison of experimental data and results from the simulation. The thesis also contains a theoretical background of piston compressors and phenomenon following the operating compressor.

Study of diaphragm pump with linear motor
Dubový, Ľuboš ; Habán, Vladimír (referee) ; Pochylý, František (advisor)
The content of this master‘s thesis is a study of diaphragm pump with linear drive. Linear motor was used as the linear drive. Thesis is well – founded by theoretic calculation of pump and its design draft. Likewise, the thesis includes optimalization of suction, or pressure, valve for pump, created by using computer fluid dynamics software. Thesis is complemented by basic view of different types of pumps based on the classification by hydrodynamic and hydrostatic pumps. Subsequently, the preview of blood – flow pumps is presented.

Fluid power heating system
Paták, Jiří ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
The theoretical part deal with problematic of fluid power heating system. The experimental part deal with measurement of the characteristic of circulation pump and measurement of valves - ball valve. The project solves the heating and hot water preparing for the new administrative building in Žďár nad Sázavou. The building has 3 floors. As a source of heat for the winter season is designed gas boiler, for hot water preparing is also used the same gas boiler. The heat source is placed in a separately accessible room.

Control system for material weighing
Komárek, David ; Zezulka, František (referee) ; Bradáč, Zdeněk (advisor)
The scope of this work is the broad issue of bulk materials weighing, partialy the conception design of control and vizualization blocks involved in weighing systems. The first part of this thesis aims at the theoretical analysis of template technology to introduce readers with issues of bulk materials weighing. The second part consist of conception design for object description of control and vizualization blocks of selected components for Step 7 and WinCC development environment. The final part focuses on experience and information gained during process of system blocks implementation.
