Rotary vane pump has rotary vane rotor transport chambers that form rotor disc space for transportation of medium from pump chamber

摘要

The vane pump has housing (1) comprising rotary vane rotors (3,12) mounted on both sides. The lamellae (10) in rotary vane rotor are radially displaceable to a rotational axis. A pump chamber (11) is formed between an inlet (7) and an outlet (8), and between rotary vane rotor outer wall (9) and a rotary valve rotor sliding face of a peripheral wall of housing. The rotary vane rotor transport chambers (17A-17H) form the rotor disc space (2) for transportation of medium from pump chamber.
