How Hydraulic Shock Absorbers Work

Movement Creates Fluid Flow

In a typical hydraulic shock absorber, relative suspension movement drives a piston through fluid. The fluid passes through designed passages and valves. The resulting resistance creates damping and converts part of the movement’s mechanical energy into heat.

Compression and Rebound

The suspension moves in both compression and extension, also called rebound. Fluid is directed through the relevant internal flow paths as the piston moves. The detailed arrangement varies with the damper construction and must not be inferred from the external product photograph alone.

Damping Characteristics

Valve design, fluid characteristics and internal construction influence the damping response. Some products offer adjustment, while others use a fixed specification. An adjustable feature must be confirmed for the exact model, together with its adjustment method and instructions.

From Principle to Product Selection

Understanding the operating principle does not establish compatibility. A replacement still needs the correct mounting dimensions, installation position and application specification. Send the existing reference and clear photographs when asking MOCI to check a product.
