pistonkompressori

A pistonkompressori, or piston compressor, is a type of positive-displacement compressor that uses a piston moving back and forth within a cylinder to compress a gas. This reciprocating motion forces the gas into a smaller volume, thereby increasing its pressure. The basic principle of operation involves an intake stroke where the piston draws gas into the cylinder, and a compression stroke where the piston pushes the gas out through an exhaust valve at a higher pressure.

Piston compressors are widely used in various applications due to their ability to produce high pressures and their relative simplicity. They are commonly found in workshops for powering pneumatic tools, in refrigeration and air conditioning systems as refrigerant compressors, and in industrial settings for processes requiring compressed air. Different designs exist, including single-acting and double-acting compressors, as well as single-stage and multi-stage configurations. Multi-stage compressors are used when very high pressures are needed, as they compress the gas in several steps, cooling it between stages to improve efficiency.

The efficiency and lifespan of a piston compressor depend on factors such as the quality of materials used, the precision of manufacturing, and proper maintenance. Lubrication is crucial for reducing friction and wear on the piston and cylinder. They can be powered by electric motors, internal combustion engines, or other mechanical means. While generally robust, piston compressors can be noisier and more prone to vibration compared to some other compressor types.
