How does a QDI shock absorber operate ?
A cross-section of QDI shock absorber is shown in the figure below. Upon impact the piston rod moves towards the shock absorber and consequently pushes the hydraulic fluid inside the accumulator to produce a resistant force. With our engineered spacing and sizing of orifices, the pressure in the inner tube remains constant throughout the entire impact stroke. QDI shock absorbers are designed to provided controlled linear deceleration and guaranteed to bring any moving object to a smooth and quiet stop.
