Title: Improvements relating to shock absorbers
IPC: F16F9/32
Filed: 1938-11-10
Abstract: 521,261. Vibration-dampers. GABRIEL CO. Nov. 10, 1938, No. 32662. Convention date, June 10. [Class 108 (iii)] A hydraulic shock absorber comprising piston 38 and cylinder 17 is characterized by a flexible cup-shaped packing ring 48 attached to the piston and overlying passages 54 in the periphery of the piston whereby pressure of liquid against the ring seals the passages and prevents passage of liquid past the piston. On the compression stroke and downward movement of piston 38 in cylinder 17, oil below piston flows through passage 52. Oil will also flow through grooves 54 and its pressure will pass between flexible cup 48 and wall of cylinder. In addition some of the oil below piston moves inwardly through opening 24 and hence through openings 21 into reservoir 18. This oil compresses air in reservoir 18 in casing 10. The amount of compression can be varied by using different amounts of oil. On the recoil stroke piston 38 moves upwards in cylinder and pressure in reservoir forces oil through opening 24 below piston. Oil above piston can at first flow only through passage 52. Pressure of oil in the cup-shaped packing 48 causes it to engage cylinder wall and prevents passage of oil through grooves 54. Plate valve 46 remains sealed until oil pressure in opening 41 and passages 42 overcomes spring 45 and allows pressure oil to flow from passage 42 to other side of piston. Tension of spring 45 can be adjusted by engaging finger 25 in opening 43a and relatively rotating cylinder and piston. As piston moves upwardly foam above piston passes through grooves 29 into annular chamber 31 on member 26 and lubricates piston rod 14.
