Abstract

510,300. Fluid-pressure servomotor-control systems. SPLADIS SOC. POUR L'APPLICATION D'INVENTIONS SCIENTIFIQUES. Aug. 16, 1938, No. 24175. Convention. date, May 30. [Class 135] A servo-assisted control mechanism for controlling the steering or stabilisation of air, land, or water-craft comprises a valve device 13, Fig. 2, which is adapted to be actuated, to control the pressure of liquid supplied from pumps 24, 24<1> to the two sides of a power device 23, by, a control member such as the joystick 14 of an aircraft. The joystick is connected to one end of a floating lever 12, the other end of which is connected to both the power device and the operating rod 19 of the rudder. Intermediate its length the lever 12 is connected to one end of a lever 5 of the valve device 13, which is shown in detail in Fig. 3, which lever is pivoted at B<1> and its other end arranged between two valve members 3, 3<1>. These valves control the flows from branch conduits leading from the pump supplies to the two ends of the power device so as to vary the pressures on the two sides of the power piston 22. Manual effort applied to the joystick 14 reacts back upon the lever 5 to move one of the valves' 3, 3<1> in a closing direction against the pressure developed thereby and open the other a corresponding amount to bring the power device 23 into operation to assist in the actuation of the rudder. The pressure difference developed. in the power device is thus proportional, to the effort applied by the operator and the movement of the power device provides a " follow-up " to restore the valves 3, 3<1> to their neutral positions. In the event of failure of the liquid pressure supply the operator can assume complete manual control. Movement of the joystick 14 in a perpendicular direction operates in a similar manner through a servo-assisted mechanism to control the transverse equilibrium of the craft. In this case however, instead of the floating-lever system 12 for actuating the valves 3, 3' a differential gear train 37 is employed as shown in detail in Fig. 8 in connection with a vehicle steering gear. Manual rotation of the shaft 28 by the driver is transmitted to the steering worm wheel 33 through a pinion 27, planet pinions 29a, 29b in a casing 34, and a pinion 30 on a shaft 31. The manual effort reacts against the casing 34, a limited movement of which is adapted to actuate the lever 5 of a valve device 13, as previously described, to bring a power device into operation to drive the shaft 31 and wormwheel 33 to assist the manual effort and provide a "followup" by restoring the casing 34 to a neutral position.
