How the steam engine? Guided by the idea of ​​how to build machines that would work for him, the man is usually freed, changed or directed, forces that exist in nature

Guided by the idea of ​​how to build machines that would work for him, the man is usually freed, changed or directed, forces that exist in nature. When water is heated to boiling point, water becomes a gas, called vapor. Para seeks to expand, ie, that pushes sideways and forward all that gets in its way. steam engine that used steam power to use it performed certain tasks.
When you look in the kettle in which water is boiling, you will see that steam escapes through the stem teapot. If the stem cap cap and hand press teapot lid, the cap will fly out with a bang. steam engine is somewhat reminiscent of the teapot where the lid rises and falls, but not falling from the teapot. while the lid rises and falls , could do some work, The steam engine piston is called the cap.
Many people have tried to make steam engines, but they did not know how to solve specific problems. In some cases, money had to be under great pressure to perform a specific job, and at such high pressures would be coming to an explosion. In other cases, water had to be repeatedly re-heated, and in fact spent a lot of coal.
Finally, James Watt invented the steam engine which steam-power which is spread directly on the piston during the power stroke of the machine. In the steam-engine piston is raised by one meter inside the cylinder through the steam pressure. Then it is the weight of the piston and piston rod descends to the starting position. As the pair entered the cylinder during entire piston stroke, spent a lot of money. In modern steam engines a small amount of steam entering the cylinder. work is mostly done by expanding steam.
Later, Watt added a third part of the steam engine - capacitor. This is an empty chamber, which is associated the cylinder through the pipe valves. steam would enter the chamber and there is again condensed into water before they were discharged from the chamber.
Watts third addition to perfecting the steam engine consists in this: he has found a way to force steam that pushes the piston in both directions. Rather than use the weight of air to push the piston down, it is arranged so that steam alone, and do this work. In this way the piston is moved up and down with vapors. It was a steam engine dvopotisni . Piston in steam engine can be connected with the pump, lever, etc. and run machines.
