SHOCK ABSORBER WITH PRESSURE-RELIEF MECHANISM |
摘要 |
A shock absorber with improved shock absorbing characteristiscs has a piston in which a vortex chamber is formed. The vortex chamber communicates with upper and lower fluid chambers via communication passages. One of the communication passage opens to the vortex chamber tangentially to produce a vortex in the vortex chamber. Within the vortex chamber, a member is normally elastically urged to narrow the area through which the fluid flows. The member is responsive to the fluid pressure exceeding a predetermined value to move against the resilient force in the direction increasing the area allowing fluid flow. A bottom fitting of similar construction and function is also disclosed. |
