Abstract

844,642. Liquid springs. DOWTY EQUIPMENT Ltd. June 18, 1958 [June 21, 19571, No. 19680/57. Class 108(3). On extension of a liquid-spring aircraft undercarriage leg 10, a lug 53 movable with a torque-resisting link 19, unseats a spring- loaded ball-valve 42 to connect the pressure chamber 34 of the liquid-spring with a hydraulic pressure pipe line 31 leading to a pressure source (not shown) on the aircraft. Specifications 560,047, 560,048 and 685,469 are referred to.
