ACE shock absorber*

ACE shock absorber*

This shock absorber is widely used in automotive suspension systems and can provide shock absorption during both compression and extension strokes, hence it is also known as a bi-directional shock absorber.

Components include: 1. Piston rod; 2. Working cylinder barrel; 3. Piston; 4. Expansion valve; 5. Oil storage cylinder barrel; 6. Compression valve; 7. Compensation valve; 8. Flow valve; 9. Guiding seat; 10. Dust cover; 11. Oil seal.

When the car wheels move closer to the body and the shock absorber is compressed, the piston inside the shock absorber moves downward. The volume of the lower chamber of the piston decreases, the oil pressure increases, and the oil flows through the flow valve to the chamber above the piston (upper chamber). Part of the space in the upper chamber is occupied by the piston rod, so the increased volume in the upper chamber is smaller than the decreased volume in the lower chamber. As a result, some of the oil pushes open the compression valve and flows back to the oil storage cylinder.

These valves contribute to the damping force of compression motion in the suspension by conserving oil. The shock absorber is stretched when the wheels are away from the body, causing the piston of the shock absorber to move upward. The oil pressure in the upper chamber of the piston increases, the flow valve closes, and the oil in the upper chamber pushes open the expansion valve and flows into the lower chamber. Due to the presence of the piston rod, the oil flowing from the upper chamber is not sufficient to fill the increased volume of the lower chamber, which mainly creates a vacuum degree in the lower chamber. At this time, the oil in the oil storage cylinder pushes open the compensating valve and flows into the lower chamber for replenishment. Due to the throttling effect of these valves, they provide damping for the suspension during stretching motion.
