Hydraulic Dampers – High-Performance Motion Control Solutions

Hydraulic dampers, also known as shocks, struts, lifts, or pistons, are essential for applications requiring precise motion control. Unlike Gas Springs, which provide lifting force at reduced speeds, Hydraulic Dampers function by reducing speed without adding force. These dampers provide effective motion and speed control through hydraulic oil damping and can operate in either the extension, compression, or both directions—with or without the support of nitrogen gas pressure.

The key feature of hydraulic dampers is their ability to adjust force based on the travel speed. This characteristic ensures smooth, controlled movement while absorbing energy and mitigating shock in various systems.

Cavitating vs Non-Cavitating Dampers

Hydraulic dampers are primarily classified into two categories:

• Cavitating Dampers: These dampers utilize a specific design to manage the movement of oil under varying pressures and are often used in systems requiring lower damping forces.

• Non-Cavitating Dampers: Designed to handle higher pressures and more demanding applications, non-cavitating dampers maintain reliable performance even in high-load conditions.

Another important design requirement for dampers is compensating for shaft volume displacement as it moves inside the tube. Unlike gas springs, which compress gas to store energy, dampers use non-compressible oil, which necessitates careful engineering to ensure reliable and consistent operation.

Types of Dampers

1. Compression Damper
   Function: Compression dampers are designed to regulate the speed when the rod is being compressed back into the tube. The force of compression is controlled, allowing for smooth deceleration as the rod retracts.
   Common Uses: These dampers are typically used in lids, doors, covers, and any application requiring speed control when moving in the compression direction. For example, automotive hoods, cabinet doors, or storage covers rely on compression dampers for smooth and controlled closure.
   Benefit: Compression dampers prevent slamming or sudden stops, ensuring smooth, controlled movements in both light and heavy-duty applications.

   

2. Extension Damper
   Function: Extension dampers provide controlled speed when the rod is extended out of the tube. The dampers slow down the extension movement, providing precise control over how quickly the rod emerges.
   Common Uses: These dampers are used in doors, lids, covers, or applications where speed control is necessary during extension (when the rod moves out). For example, tailgate supports or furniture lifting systems often use extension dampers to control the speed at which they open or close.
   Benefit: Extension dampers prevent abrupt or jerky motions during the extension phase, ensuring safe and predictable operation.

3. Cavitating Damper
   Function: Cavitating dampers are filled with a mixture of oil and air. When the shaft compresses, the air is compressed, absorbing some of the movement. In vertical or near-vertical applications, the oil and air remain separated due to gravity, providing effective damping. However, when used horizontally, the oil and air mix, causing cavitation, which leads to irregular damping forces. This results in jerky movements as the shaft moves in and out.
   Common Uses: Cavitating dampers are best suited for vertical or near-vertical applications where gravity ensures oil and air separation, such as furniture or machinery.
   Benefit: These dampers are cost-effective for specific applications but are limited in horizontal configurations where smooth, consistent damping is required.

4. Non-Cavitating Damper
   Function: Non-cavitating dampers prevent the mixing of oil and air through floating pistons, air bags, or foam, ensuring a smooth, consistent damping force regardless of mounting orientation. This design eliminates the risk of cavitation, ensuring reliable, even performance in both vertical and horizontal applications.
   Common Uses: Non-cavitating dampers are versatile and used in applications such as automotive suspension systems, recreational vehicles, and machinery that require precise motion control in any position. They are especially valuable in situations where consistent damping is crucial, such as heavy-duty doors, lid systems, or adjustable furniture.
   Benefit: Non-cavitating dampers offer reliable performance in various orientations and provide precise, smooth motion control under various load conditions.
