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. An external heat exchanger is coupled to the base of the shock absorber to receive working hydraulic fluid which is passed through the blow off valve, and to return the working hydraulic fluid to the shock absorber after passage through the heat exchanger.
