Abstract
A dual action piston assembly 10 includes a piston 12 with compression passageways 18 and rebound passageways 20 with each set of passageways covered by a valve disc 22 and 24 respectively. Each valve disc is seated on a land by a spring biased valve seat 26 and 28 respectively. The rebound valve seat 28 has a debossed section 34 which is spaced away from the valve disc 24 to form a clearance 36 such that when fluid pressure within rebound passageway 20 presses against valve disc 24, the valve disc portion under the debossed section 34 flexes to modulate fluid flow before the valve seat 28 lifts from a higher pressure within the rebound passageway against a spring 42 to allow for smooth modulation of hydraulic fluid passing therethrough.
