Abstract

A hydraulic transmission system uses two identical machines. One machine operates as a pump and supplies fluid at pressure to the second machine which operates as a motor. Each machine consists of a cylindrical casing with end cover plates. A rotor of variable eccentricity runs in bearings mounted in the cover plate. The rotor has three sliding vanes (5,6,7) which are kept in contact with the bore of the casing by a central shaft. By varying the eccentricity of the rotor, the volume of fluid flowing through the machine per revolution can be controlled. The ratio of speed reduction between the pump and the motor is thus a function of the eccentricities of the rotors of both machines.
