Damper piston

Damper piston is an important mechanical component in the railway system, mainly used to convert the pressure energy of the fluid (such as gas, liquid) into mechanical energy, or to achieve sealing and reciprocating motion. Its core function is to carry out linear movement in the cylinder or damper or hydraulic cylinder and drive related mechanical devices, which is widely used in the key parts of the locomotive power system, braking system and suspension system.

Main role

Energy conversion: In a steam locomotive or internal combustion engine, the piston converts the pressure energy of steam or gas into mechanical energy to drive the crankshaft to rotate;

Brake control: In the air brake system, the piston pushes the brake cylinder through compressed air to realize the braking and relief of the train;

Damping function: In the hydraulic suspension system, High-Performance Piston for Rail Dampers adjusts the damping force through the flow of hydraulic oil to improve the smooth running of the train;

Seal and guide: The piston fits closely with the cylinder block to ensure that the medium does not leak while guiding the direction of movement.

Typical application

• Power system: engine pistons for steam locomotives and diesel locomotives;

• Braking system: piston in the air brake cylinder;

• Suspension system: Non-Standard Piston assembly in hydraulic shock absorber.
