Abstract (en)
[origin: EP2642073A2] The pump (1) has a rotatingly mounted inner rotor (2) connected with an outer rotor (4) via a pendulum (3) and defining multiple radial grooves (5) that retain the pendulum. The grooves comprise two groove walls (8) respectively continuing via a rounding region (9) into a shared groove base (10). The rounding region has variable groove radii and continues with a reduced curvature jump into the groove base and the groove walls, where the groove radii are greater in the transition to the groove walls and to the groove base than between the groove walls and the groove base.
