A mechanism employed in pneumatic systems, particularly within air compression apparatus, regulates the operational cycle of the unit. It achieves this regulation through a smaller, controlling component that dictates the behavior of a larger main valve. For instance, this control feature might activate or deactivate the compressor based on pressure thresholds within the storage tank.
This methodology provides several advantages, including automated system management, contributing to energy efficiency, and extending the lifespan of the compression machinery. Historically, such control schemes have evolved from purely mechanical designs to incorporate electromechanical and fully electronic solutions, enhancing precision and responsiveness.
