초록 ▼

A shock absorber with provisions for independent external adjustment of both rebound and compression pressure sensitive valving. The shock absorber makes use of a rebound tube located internal to the piston rod to transmit fluid from the rebound chamber to an external line. External lines from both the rebound and compression chambers are connected to an external valving reservoir. The valving reservoir contains separate rebound and compression metering devices. The metering devices are externally adjustable and consist of spring loaded needles.

A hydraulic shock absorber which consists of three concentric hollow cylinders, an outer cylinder, a piston rod and, a rebound tube, the outer cylinder is attached in a fluid tight manner at one end to an upper cap which has provisions for attachment to the vehicle frame, and the other end of the outer cylinder is attached in a fluid tight manner to a bottom cap, the piston rod is formed from a hollow cylindrical tube of smaller diameter than the inside diameter of the outer cylinder and is fitted concentrically thru an opening in the bottom cap, said piston rod is free to slide within said bottom cap and a seal is provided to prevent the escape of fluid where the piston rod passes thru the bottom cap, the end of the piston rod which is external to the outer cylinder provides a mounting point for the vehicle suspension, the end of the piston rod which is internal to the outer cylinder is fitted with a piston, said piston is internal to and concentric with the outer cylinder, said piston divides the shock assembly into two main chambers, the rebound chamber and, the compression chamber, the piston and piston rod are fixed together as an assembly, the piston and piston rod assembly are free to slide within the outer cylinder, the rebound tube is a hollow cylindrical tube internal and concentric to the hollow piston and piston rod assembly, the rebound tube is connected at one end to the rebound exit passage located in the upper cap, the other end of said rebound tube is open to provide means for fluid to enter, a piston rod internal chamber is created by the inner cylindrical surface of said piston rod and the outer cylindrical surface of said rebound tube being of different diameters and being mutually concentric form a cylindrical space therebetween, an opening is provided in said piston and piston rod assembly to provide means so that fluid may pass from said rebound chamber to said piston rod internal chamber, the rebound tube to piston rod clearance is large enough to permit the flow of fluid between the outer diameter of the rebound tube and the inner diameter of the piston rod with negligible restriction, a rebound tube seal is formed from an annular sealing material placed in the piston and piston rod assembly to provide a means to prevent the flow of fluid between the compression chamber and the piston rod internal chamber while permitting the flow of fluid between the piston rod opening and the rebound tube opening, a rebound exit passage is open to an external rebound line, and thus the rebound chamber is connected directly to the external rebound line via the rebound tube.
