<p>In order to reduce noise in a shock-absorber, a screen (10) pierced by ports (8) surrounds a valve (3) which is normally held by a spring (5) against a seat (4) in the bottom plate (2) of the cylinder (1). In this way, any pressure shock generated by the descending piston (not shown) is applied to the underside rather than the top of the valve. <IMAGE></p> |
