ABSTRACT:
A rotary vane hydraulic motor wherein pressurized liquids are admitted to the working chambers through intake passages oriented tangentially to the rotor peripheral surface. Each intake passage has two flat parallel side surfaces spaced apart approximately the transverse width of the working chamber, such that the liquid readily fills the chamber width dimension as it enters the chamber, without excessive turbulence or flow disruptions.
