Which components are essential for a pneumatic circuit?

In a pneumatic circuit, essential components are those that facilitate the generation, control, and application of compressed air. A compressor is crucial as it generates the compressed air needed to drive the system. Valves play a vital role in controlling the flow and direction of the compressed air, enabling the system to function effectively. Actuators, such as cylinders, convert the energy from the compressed air into mechanical work, performing tasks like lifting, pushing, or pulling. Additionally, air reservoirs store the compressed air, ensuring a steady supply and buffering against fluctuations in air pressure.

The combination of these components—compressor, valves, actuators, and air reservoirs—forms the backbone of any pneumatic system, allowing it to perform its intended functions efficiently. Other options may include components that are important in different contexts (like hydraulic systems) but do not encompass the fundamental requirements for a pneumatic circuit specifically.
