Abstract: A shock absorber includes a rebound valve assembly which performs the flexing disc function normally required for allowing the passage of fluid from one side of a piston assembly to the opposite side during the stroke of the shock absorber. The rebound valve assembly also incorporates a blow off function which increases the fluid flow through the piston when the fluid pressure being exerted upon the rebound valve assembly exceeds a specified level. The blow off feature utilizes a coil spring to protect both the shock absorber as well as the suspension system into which the shock absorber is assembled.

Abstract: A valve for controlling fluid flow through a passage defined by a valve body or a piston includes a valve disc which abuts the valve body or the piston. The valve body or the piston defines a first land for supporting the valve disc, a second land for supporting the valve disc located radially inward from the first land and a support surface for the valve disc located between the first and second lands. This valve disc abuts the first and second lands and a clearance is defined between the valve disc and the support surface.

Abstract: A shock absorber has a pressure tube with a piston assembly slidably disposed within the pressure tube and attached to a piston rod. The piston assembly divides the pressure tube into an upper working chamber and a lower working chamber. The piston assembly includes a compression and a rebound valve assembly. The piston assembly also includes a housing attached to the piston rod which defines a pressure chamber within which is slidably disposed a piston to define upper and lower fluid chambers. The pressure chamber is in communication with the upper working chamber through a passageway extending through the piston rod. The housing, piston and fluid chambers provide two stage damping in rebound and compression with a smooth transition between soft and firm damping.

The piston assembly divides the pressure tube into an upper working chamber and a lower working chamber. The piston assembly includes a compression and a rebound valve assembly. The piston assembly also includes a housing attached to the piston rod within which is slidably disposed a piston to define a closed chamber. The closed chamber is in communication with one of the working chambers through a passageway extending through the piston rod. The housing and piston provide two stage damping in rebound and compression with a smooth transition between soft and firm damping.

Abstract: A shock absorber utilizes a single flexing disc assembly includes a flexing disc which is capable of performing the flexing disc function normally required for allowing the passage of fluid between the two sides of a shock absorber while also providing the blow off function. The flexing disc is backed by a ridge formed on a spring seat. The ridge defines a ring that is concentric with the central long axis of the piston rod. Under normal rebounding conditions, the pressure of rebounding damping fluid builds to the point that the flexing disc is opened somewhat by flexing to allow normal bleedthrough. However, in the event that the rebound pressure builds to a higher, predetermined value, the valve flexes to an extreme degree against the ridge formed on the spring seat. In this manner, the ring acts as a fulcrum, and a quantity of damping fluid is allowed to pass thereby until normal rebound pressure values are reached.
