ABSTRACT:
A rotary vane-type hydraulic fluid flow divider in which a rotor is mounted on a stub shaft for free rotation within a housing. A plurality of vanes are individually slidably mounted in radial slots on the rotor and engages a surrounding cam ring to form fluid cavities. A pair of cam plates are mounted in fixed position with respect to the cam ring and have radially orientated surfaces that engage the vanes and position the vanes adjacent to the cam ring. The fluid cavities communicate with a common inlet and a pair of outlets for dividing inlet fluid flow between the outlets.
