Abstract (en)
[origin: EP0736691A1] The gerotor pump has the main exterior diameter (D1) of the external gear (23) at one point on the height of the exterior gear is reduced to the value of the theoretical value of the depth of the tooth of the gear. The gear has at least one continuous ring connected to and supporting the teeth (29) to assure radial feeding of the fluid across the spaces (30) between the teeth of the gear. The external gear can have a ring with a second exterior diameter (D2) superior to that of the first.
