A rotary vane vacuum pump is an oil-sealed rotary Oil-free Air Compressors displacement pump. The pumping system
consists of a casing (1), an eccentrically 
installed rotor (2), vanes that move radially under spring
pressure (3) and the inlet and store (4). The wall plug valve can be oil-sealed. The inlet valve was created as a
vacuum safety valve that is always open during operation. The working chamber (5) is situated
inside the casing. Rotor and vanes divide the functioning chamber into two separate spaces having
adjustable volumes. As the rotor turns, gas flows into the enlarging suction chamber until it really is sealed
off by the second vane. The enclosed gas is definitely compressed before outlet valve opens against
atmospheric pressure. In the case of gas ballast procedure, a hole to the outside is opened, which
empties into the sealed suction chamber on the front side.
The Rotor moves by using a motor attached to it.
