Pneumatic shock absorber with spring loaded bellows - having restricted outlet ports in base spaced from support plate by washer

摘要

The pneumatic absorber has a base joined screwed into the support plate (3). The base has two air holes and an inlet valve. The bellows (2) are clamped onto the base by the circular clip (6), the bellows being fitted with a helical spring (8). The bellows are conical and flexible to allow lateral movement. Air is admitted to the bellows with the inlet valve open, and is expelled with difficulty through the restricted outlet ports.
