<p>A variable pressure ratio hydraulic transducer comprises a vane type armature which freely rotates within a cam ring. The armature includes a radially extending passage intermediate each pair of vanes, the armature rotates about a porting ring having ports for communication with the armature passages, and includes a centrally mounted control vane having passage means therein, port means connects the transducer to a source of pressure and to an outlet in pressure ratio relationship to the source of pressure, and to a reservoir. Means are provided for manually controlling the position of the control vane for varying the pressure ratio of the transducer.</p> |
