ABSTRACT OF THE DISCLOSURE A power steering device includes a housing which couples to a pressure source in order to provide a power assist to the rotation of an output member upon rotation of an input member. The input member and the output member are rotatably supported within a housing bore such that the output member cooperates with an enlarged portion of the housing bore to define a plurality of pressure chambers. Slots on the input member and passages on the output member communicate the pressure source to one set of pressure chambers so that the increased pressure in these pressure chambers imparts rotation to the output member in response to rotation of the input member. A pair of cavities between the input and output members communicate the input member slots with the output member passages and projections on the output member oppose the slot side walls to limit rotation between the input member and output member. The output member supports a plurality of vanes within the enlarged diameter portion of the housing bore and is eccentrically mounted within the enlarged portion so that pressure communicated to chambers defined by the vanes imparts rotation to the vanes and output member. A pressure feedback chamber is provided between the input member and the housing.
