Abstract

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.

Pendulum slider pump (1) with a rotating inner rotor (2), which is connected via pendulum (3) with an outer rotor (4). Essential to the invention is
- that the grooves (5) each have two groove walls (8), which pass over in each case a rounding region (9) in a common groove base (10),
- That the rounding region (9) has variable Nutenradien (s) and is designed such that it merges with or without at least reduced curvature jump (12) in the groove base (10) and / or the groove walls (8),
- That the Nutenradien (s) in the transition to the Nutenwänden (8) and the groove bottom (10) are greater than in between.
