ABSTRACT:
A reversible fluid device (motor/pump) of the sliding vane type, in which the vanes slide in radial slots formed through the cylindrical periphery of a rotor from side to side in a direction parallel to the axis of rotation of the rotor. Sliding of the vanes is effected by opposed complementary cam surfaces at either end of a cylindrical chamber within which the rotor rotates. The periphery of the rotor and a top edge of each vane, are maintained in constant sliding contact with the cylindrical chamber wall. Opposed edges of the vanes are in constant contact with the cam surfaces. Thus, as the rotor rotates, the vanes, rotor, chamber and cam surfaces define varying volume pressure cells. Selective pressurization of these cells via fluid conductors rotates the rotor (motor operation); rotation of the rotor selectively pressurizes the conductors (pump operation).
