1,244,791. Fluid-pressure servomotor systems. BENDIX CORP. Jan.23, 1969 [Feb.16, 1968], No.3894/69. Heading G3P. In a power boost mechanism for controlling actuation of an output shaft 20 as a function of the control actuation of an input shaft coaxially arranged therewith the mechanism comprises a power transmitting mechanism operatively connecting the input and output shafts, characterized in that the power transmitting mechanism is arranged in a movable carriage member 30 pivotally carried by the input and output shafts so as to be operative to actuate a control valve 52, 54 controlling pressurized fluid-flow from a pressure source to a motor 90, 92 operatively connected to said output shaft via 2 rack 28 to drive the output shaft in rotation when the load driven by the output shaft 20 requires an output torque above a predetermined value as defined by the preload resistance of the springs 43. |
