Rotary Sliding Vane Compressor: This is another positive displacement one, uses sliding vanes surrounding the eccentrically rotating impeller for compressing. It was invented by Charles C. Barnes of Sackville, New Brunswick, who patented it on June 16, 1874. Reciprocating and centrifugal compressors are the most common. Mattei Compressor Advantages. The service life is high compared to the unbalanced type due to less wear and tear. Although this rotating positive displacement device has some similarities to a rotary vane compressor, there are also distinct differences. The advantages of Mattei rotary vane compressors for the automotive industry start at a very basic level, smaller footprint, pulse-free air, low oil consumption, very little maintenance, and decreased power consumption. A rotary vane compressor is a volumetric rotary compressor, consisting of a rotor that rotates in a stator. A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. Hydrovane Rotary Vane Compressors Hydrovane Advantages. The vane splits the space between the cylinder and the rolling piston into two sections (suction and discharge). Long life and reliability by design - Proven, simple and long-lasting technology with fewer moving parts, allowing up to 100,000+ operating hours being achieved with no expensive Air End change or refurbishment, when correctly serviced with genuine parts and lubricants. A rotary-vane compressor is also known as a rotary piston compressor because the function of the vane is similar to that of a piston (shown in Figure 3).
