Title: Improvements in or relating to hydraulic shock absorbers and the like differential pressure operated damping means
IPC: F16F9/28
Filed: 1938-01-25
Abstract: 506,552. Hydraulic shock-absorbers. ARMSTRONG, F. G. G. Jan. 25, 1938, No. 2362. [Class 108 (iii)] In a shock-absorber of the type wherein one or more restricted passages form a resistance to fluid flow between the parallel cylinders of a pair of pistons a greater resistance is effected on the return movement of the pistons towards their normal positions than on the outward movement away from said normal positions by ensuring that either piston on its suction stroke sweeps a greater volume of its cylinder than the other piston on its compression stroke, and allowing the increased volume of sweep to be taken up on the return stroke by leakage past the piston walls. In the form shown in Fig. 1, the crank 15 operates spring-loaded pistons 18, 19. Since the nose-pieces 16, 17 of the crank are below the centre of the shaft 14, an angular movement of the crank produces a greater displacement in whichever piston moves upward than in the other which moves downward. Fluid passes from one cylinder to the other through the conduit 23 and additional fluid is drawn from the reservoir 24 into one cylinder through a one-way valve such as 37, Fig. 3. On return movement of the crank this additional fluid must escape between the pistons and the cylinder walls. A relief valve may be provided to prevent a hydraulic lock. In a modification, Fig. 3, a crank 36 and connecting-rods 32, 33 replace the crank 15. Specification 395,065 is referred to.
