ilmamoottorit

Ilmamoottorit, also known as air engines or pneumatic motors, are a type of engine that uses compressed air as its working fluid. They operate by converting the energy of compressed air into mechanical work, typically rotational motion. The basic principle involves directing compressed air into a cylinder, where it expands and pushes a piston or rotates a turbine. As the air expands, its pressure drops, and this expansion drives the mechanical output. Once the air has done its work, it is exhausted from the engine.

Ilmamoottorit are often favored for their safety in hazardous environments because they do not produce sparks or emit flammable exhaust gases, making them suitable for use in mines, chemical plants, and other potentially explosive atmospheres. They also tend to be lightweight and can operate at high speeds. Their construction is generally simpler than that of internal combustion engines, leading to lower maintenance requirements.

Applications for ilmamoottorit are diverse. They are commonly found in pneumatic tools such as drills, grinders, and impact wrenches. In industrial settings, they power conveyors, mixers, and robotic actuators. They can also be used in specialized vehicles, like some types of mine locomotives, and in breathing apparatus for divers. The efficiency of ilmamoottorit can vary depending on their design and operating pressure, and they typically require a source of compressed air, often provided by a compressor.
