Abstract: A shock absorber for a vehicle including a pressure tube defining a fluid chamber, a piston body disposed within the fluid chamber, and a valve assembly. The piston body divides the fluid chamber into an upper working chamber and a lower working chamber. The piston body defines a first bleed passage and a first blowoff passage that each extend through the piston body between the upper working chamber and the lower working chamber. The valve assembly includes a restriction disc including a ring, a first finger extending radially outward from the ring, and a second finger extending radially outward from the ring. The first finger is configured to cover the first bleed passage, the first finger having a first bleed orifice, wherein the first bleed orifice remains open regardless of position of the restriction disc. The second finger is configured to at least partially cover the first blowoff passage.

Abstract: A shock absorber for a vehicle including a pressure tube defining a fluid chamber, a piston disposed within the fluid chamber and including a fluid passage, and a valve assembly. The valve assembly includes a restriction disc, an orifice disc, a fulcrum disc, and a check disc. The restriction disc includes a first ring, a first finger, and a first orifice. The first finger covers the fluid passage. The orifice disc includes a second ring, a second finger, and a second orifice. The second finger overlaps the first finger, and the second orifice is aligned with the first orifice. The check disc includes a third ring and a third finger above the second finger. The fulcrum disc has a fourth ring. Modifying the outer diameter of the third ring and the outer diameter of the fourth ring alters a damping response of the shock absorber.

Abstract: A shock absorber for a vehicle including a pressure tube, a piston rod, and a piston assembly. The piston assembly includes a first disc, a second disc, and a piston body. The piston body includes first and second surfaces and first and second fluid passages. The piston body further includes a first circumferential land surrounding the first fluid passage and a second circumferential land surrounding the second fluid passage. The first circumferential land is located a first distance from the first surface. The first disc is selectively driven into engagement with the first circumferential land. The second circumferential land is located a second distance from the first surface. The second circumferential land is between the first surface and the first circumferential land. The second disc includes a first portion in sealing engagement with the second circumferential land and a second portion spaced apart from the piston body.
