Abstract
This invention describes a mechanism containing two coaxial rotators, embedded on a driveshaft, (1a, 1b) that spin alternately with two velocities. Each rotator has at least two vanes (2) and during the rotators' spin chambers of variable capacities form between the vanes. When the vanes touch together the velocities of the rotators change (2). Rotation speed changes from V1 to V2 and vice-versa are enabled by gearshifts consisting of two-speed ratchets (3) interlocked with rotators' shafts (1a, 1b) that transmit force from and to steering ratchets (4). At a constant velocity of the steering ratchet (4) after its every 180° rotation the angular velocity of the two-speed ratchet (3) and rotator change. The correct functioning of the whole mechanism is provided by engagement of the steering ratchet, transporting force from and to the two-speed ratchet (3), with the coaxial steering ratchet (4) transporting force from the rotator (1b).
