Abstract (en)

[origin: EP1118772A1] The pump or motor (10) has a drive mechanism with two engaged gear wheels (28, 30) supplying fluid from the inlet to the outlet, which are connected by supply grooves (52, 54) to the tooth chambers enclosed by the gear wheels. The seal between the induction and compression sides of the pump or motor is achieved by a special reversing mechanism, automatically adapting itself to the rear flank play (64).
