Problems solved by technology

[0006] Generally speaking, the main disadvantages of driving and driven machines of different structures are expensive, complicated manufacturing process, and bulky equipment itself

The main disadvantages of most machines of existing construction are that they are expensive to manufacture and, due to the high coefficient of friction, require regular lubrication, resulting in a relatively complex lubrication system and thus low utilization of liquid energy, eg, very complex manufacturing processes, relatively expensive Expensive and noisy compressors (standard piston compressors); pumps that use many working circuits (2 to 10 and more) to create high pressure, heavy and expensive equipment like 100-200 Bar High-pressure pumps, which are expensive and complex in process; steam turbines that require special motors to start; vacuum equipment with high-speed rotating working circuits and low vacuum rates; very complicated internal combustion engines, etc.
