Abstract

726,327. Hydraulic shock-absorbers. GIRLING, Ltd. Oct. 6, 1953 [Oct. 16, 1952], No. 25937/52. Class 108 (3). A valve assembly for a direct-acting piston-and-cylinder hydraulic shock-absorber, comprises an annular seating 22 at the end of an axial bore 23 in the piston rod 12, for a valve head 25 loaded by a compression spring 27 abutting a spring cup or plate 28 which is located by an inwardlydirected lip or flange 29. The lip 29 is produced by deformation of the outer end of a sleeve 30 which encloses the spring and valve head, and is secured on the outer end of the piston rod. The loading of the spring 27 is determined by the extent of axial deformation of the lip. In the construction shown, the deformation is effected by shear-riveting. In another construction (Fig. 4, not shown), the lip 38 is formed by a reduced-thickness end of the sleeve 30, which is spun or swaged over. The cup 28 may be replaced by a plate (Fig. 3, not shown), which has no aperture. Flow then takes place through ports 39 in the sleeve 30.
