Abstract (en)

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.

Abstract (de)

Pendelschieberpumpe (1) mit einem rotierend gelagerten Innenrotor (2), der über Pendel (3) mit einem Außenrotor (4) in Verbindung steht. Erfindungswesentlich ist dabei, - dass die Nuten (5) jeweils zwei Nutenwände (8) aufweisen, die über jeweils einen Rundungsbereich (9) in einen gemeinsamen Nutengrund (10) übergehen, - dass der Rundungsbereich (9) variable Nutenradien (s) aufweist und derart ausgebildet ist, dass er ohne oder mit zumindest reduziertem Krümmungssprung (12) in den Nutengrund (10) und/oder die Nutenwände (8) übergeht, - dass die Nutenradien (s) im Übergang zu den Nutenwänden (8) und zum Nutengrund (10) größer sind als dazwischen.
