FLOW-OPTIMISED VANE PUMP

The invention relates to a vane pump for conveying liquids, in particular viscous oils, which vane pump comprises: a rotor (2) having sliding slots (23) in which movable vanes (3) are held and can becountersunk in relation to a rotor radius (r); a pump housing (1) comprising a pump chamber (10), whi...

More Information
Summary:The invention relates to a vane pump for conveying liquids, in particular viscous oils, which vane pump comprises: a rotor (2) having sliding slots (23) in which movable vanes (3) are held and can becountersunk in relation to a rotor radius (r); a pump housing (1) comprising a pump chamber (10), which encloses the rotor (2); and an inlet (5) and an outlet (6), which open into the pump chamber (10) at at least one end face of the rotor (2); radial elevations (21) protruding, with respect to the sliding slots (23), over the circumference of the rotor (2), which elevations form a rotor radius (r) on either side of the vanes (3) that can be countersunk, and radial pockets (20) being recessed, relative to the rotor radius (r), between the radial elevations (21). Within the radial elevations (21), recesses (4) are formed on the at least one end face of the rotor (2) at which the inlet (5) and the outlet (6) open, which recesses provide rotating anticipatory control geometry for reducing pressure spikes in the vane
