rotary vane pump

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