How Does a Rotary Compressor Work?
Rotary Basics A rotary compressor, or rotary vane compressor, is a device used for moving a fluid through a system. Rotary compressors are used for compressing air, powering vacuum pumps, moving steering fluid inside a car and numerous other uses. Sometimes, several rotary vane compressors are combined together into a multi-stage compressor that can create more pressure. Rotary Compressor Structure As the name implies, a rotary vane compressor has a central, spinning rotor and a number of vanes. The rotor assembly is encased inside of a sealed container with an inlet and outlet valve. The vanes are spring-loaded so that they constantly push against the outside of the case, creating a tight seal. The rotor can be in the center of the housing, but it’s often offset to one side. How it Works When a rotary blade spins past the inlet valve, it creates a vacuum. The fluid flows out of the valve behind it, filling the vacuum. As it approaches the outlet valve, the chamber shrinks. This create
