  • Patent number: 5220983
    Abstract: A monoflow shock absorber is provided with a blow off valve which provides the principal flow restriction during both extension and compression of the shock absorber. The force biasing the blow off valve closed is controlled by a control piston which is connected to the blow off valve plate by a rigid, solid rod. The piston responds to a pressurized control fluid, the pressure of which is selected by a high speed pressure regulating device such as a servo valve. This system provides high speed adjustment of the damping force of the shock absorber, substantially independently of the stroking speed of the shock absorber. The shock absorber includes a cylinder in which a working piston moves, and the cylinder is closed at one end with an inner cylinder head assembly made up of a body and a cap, which define a manifold therebetween.
