Abstract
A power steering device includes a housing which journals coaxial input and output shafts. Drivingly connected to the input shaft is an eccentric which rotatably carries a gear wheel. The gear wheel is prevented from rotating in the housing so that it gyrates when the input shaft rotates. An internally toothed ring meshes with the gear wheel and is drivingly connected to the output shaft. The internally toothed ring defines a greater number of gear teeth than does the gear wheel so that gyration of the gear wheel incident to the rotation of the input shaft drives the output shaft via the internally toothed ring. A valve device is responsive to rotation of the input shaft relative to the output shaft to control fluid flow to and from a fluid motor. The fluid motor is coaxial with and drivingly connected to the output shaft so as to increase the torque derivable from the output shaft incident to rotation of the input shaft.
