Hydrodampers, also known as hydraulic dampers or shock absorbers, are mechanical devices designed to absorb and dissipate kinetic energy. They are commonly used in vehicles to control the motion of springs, preventing excessive bouncing and improving ride comfort and handling. The fundamental principle behind a hydrodamper involves the resistance to fluid flow through a restricted orifice. When a suspension component moves, it forces a hydraulic fluid (typically oil) through a narrow passage. This restricted flow creates friction and converts the kinetic energy of the movement into heat, which is then dissipated into the surrounding environment.

Hydrodampers consist of a cylinder filled with hydraulic fluid, a piston that moves within the cylinder, and a rod attached to the piston. As the suspension compresses or extends, the piston moves, pushing the fluid through small holes or valves within the piston assembly. The size and number of these orifices, as well as the viscosity of the fluid, determine the damping force. Many modern hydrodampers also incorporate gas pressure, often nitrogen, within a separate chamber or as part of the fluid. This gas pressure helps to prevent cavitation (the formation of vapor bubbles in the fluid) and can also contribute to the overall damping characteristics. They are essential components in automotive suspension systems, as well as in industrial machinery, aircraft landing gear, and other applications where controlled movement and vibration reduction are required.
