A TWIN ROTOR PUMP, MOTOR AND/OR DRIVE ASSEMBLY

摘要

The present invention relates to a pump, motor and/or drive assembly and more particularly to such an embodiment which is able to provide an operatable continuously variable transmission which by virtue of its twin rotor arrangement can be of much smaller design and arrangement that one would expect from conventional operated continuously variable transmission pumps, motors and/or drives. The transmission is also adapted to transmit a torque demand from the assembly such that the torque demand on the drive for the motor or pump is substantially constant.
