Hydraulic shock absorber with pressure sensitive external valving

摘要

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.
