A shock absorber comprising a pressure forming tube (18) forming a working chamber; a piston (12) disposed for movement in an axial direction within said pressure tube (18), said piston (12) dividing said working chamber in the axial direction into an upper working chamber (20) and a lower working chamber (22), said piston (12) defining a plurality of fluid passages (30, 42, 43) extending through said piston; a first valve assembly engaging said piston (12), said first valve assembly comprising: a first disc (44) engaging said piston (12) to close at least one of said plurality of fluid passages (30, 42, 43), said entire first disc (44) being movable in the axial direction with respect to said piston (12); a first interface (46) engaging said first disc (44), said entire first interface being movable in the axial direction with respect to said piston (12); a first interface disc (48) engaging said first interface (46), said first interface disc (46) urging said first interface (48) into engagement with said first disc and said first disc into engagement with said piston (12); and a piston rod (14) attached to said piston (12) and extending out one end of said pressure tube (18), an open gap being defined between said piston (12) and said first interface. |
