Abstract: 708,074. Dashpots. DUNLOP RUBBER CO., Ltd., and MACLAREN, O. F. June 16, 1952 [June 30, 1951], No. 15567/51. Class. 108(3) [Also in Group XXXIII] A dashpot for an aircraft t castering wheel assembly (see Group XXXIII) comprises a plunger 8 operating in a cylinder 1, a pair of conduits 13, 14 (13 only visible in Fig. 1) and 16, 17 extending from each end of the cylinder to the opposite side of the plunger 8 (when it is in mid-position), each conduit having a non- return valve 18 and an adjustable restrictor valve 19. As shown, the valves 18, 19 of each conduit are disposed respectively at each of its ends. Movement of the plunger 8 in either direction from the mid-position shown, cuts off the outlets of one pair of ports, (e.g. the outlets 15 of the ports 13, 14 for downward plunger movement). One conduit 17 of the other pair 16, 17 then provides a flow from one side of the plunger to the other which is determined by the setting of the valve 19. Flow through the conduit 16 is prevented by its return valve. On the return movement of the plunger, restricted flow is provided by the valve 19 of the conduit 16, while flow through the conduit 17 is prevented by its non-return valve 18. The valves 19 are adjusted so as to provide greater damping of the return movement of the plunger 8 to the central position. Expansion of liquid is provided for by a spring-loaded piston 26 in a bore 25 in the plunger. The bore 25 is connected by ducts 31, 32 with the main cylinder space on either side of the plunger. Specifications 507,162 and 691,874, (both in Group XXXIII] are referred to.
