Title: Pneumatic damper cylinder with hollow piston - has two pressure chambers to produce two pressure gradients for differential damping action
Inventor: KNECHT HEINZ
IPC: F16F9/02
Filed: 1976-06-09
Abstract: A pneumatic shock absorber has a hollow piston (3) which is retained inside a cylinder (5); thus two gas filled pressure chambers (1, 2) are obtained. When an external load is applied on the piston end (4), the gas in chamber (1) is further compressed due to the piston movement. When the piston ring (12) reaches a bypass groove in the cylinder wall (16), the two gas pressure chambers (1, 2) are being connected between each other. Thus further piston movement compresses the gas volume in both chambers. This produces a damping action that has two different pressure gradients.
