Abstract

1,036,934. Aircraft undercarriages. DOWTY ROTOL Ltd. July 29, 1964 [July 29, 1963], No. 30011/63. Heading B7G. [Also in Division G3] The load differential between two legs 11, 12 of an aircraft landing gear is reduced (e.g. while cornering or in a side wind) by an actuator 28 (Fig. 2, not shown) which supplies liquid to the more heavily loaded leg and receives it from the less heavily loaded leg. Each leg comprises a piston 19 in a cylinder 15 and the load differential is sensed by a pressure transducer, such as Bourdon tube 64 connected to a potentiometer 66, which transmits signals through a control unit 75 to the split winding 61 of a flapper valve 47. Movement of the valve 47 reduces the flow through one of two nozzles 48, 49 supplied from a pipe 57, and hence increases the pressure at one end of a valve 51, allowing fluid to pass from a supply pipe 45 to one side of a piston 32 connected to the piston 33 of the actuator. In another embodiment (Fig. 3, not shown), the actuator 28 is replaced by a piston fixed to each cylinder 15 and mounted in a cylinder connected to the valve 51.
