A rotary vane vacuum pump is an oil-Motorbase sealed rotary displacement pump. The pumping system
consists of a housing (1), an eccentrically installed rotor (2), vanes that move radially under spring
power (3) and the inlet and store (4). The outlet valve can be oil-sealed. The inlet valve was created as a
vacuum safety valve that is always open during procedure. The working chamber (5) is located
inside the casing. Rotor and vanes divide the operating chamber into two individual spaces having
variable 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 certainly compressed until the outlet valve opens against
atmospheric pressure. Regarding 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 making use of a motor mounted on it.
