Apart from controlling the movement of springs and suspension, dampers keep your tyres in contact with the ground at all times and whenever a tyre loses contact with the ground, your ability to drive, steer and brake is compromised. And if the springs are allowed to bounce uncontrollably, the car will wallow and the ride quality will lead the car's occupants to feel sick after a while.
Inside the damper's sealed cylinder are valve passages and hydraulic fluid. As the suspension travels up and down, the piston moves inside the cylinder. As this occurs, the flow of fluid is slowed by the valve passages, which in turn controls the speed of the piston's motion and therefore the movement of the suspension.
Dampers automatically adjust to road conditions and the faster the suspension moves the more resistance the dampers provide. Why are they so important? Dampers play a vital role in the ride and handling of your car. Aside from giving you a comfortable ride, dampers help manage a vehicle's stability, cornering, handling, traction, braking, stopping distance, and overall safety.
Unlike a flat tyre or blown headlight globe, dampers' performance deteriorates gradually over a long period of time, and often unknowingly, drivers adjust their driving style to compensate. How can you tell they need replacing? When your car is moving, the dampers are constantly working, so they do wear out. But there are warning signs to tell you your dampers need replacing. Nose diving or swerving when braking hard indicate that worn dampers can no longer control the weight transfer of the car and the piston in the damper is compressing too rapidly.
After hitting a bump, your car should fall and rise back to its original position and settle after one, or two rebounds at most. If it doesn't, it means the dampers are worn out as they no longer control the bounce of the springs. When dampers are worn, cars become more unstable, which is magnified in SUVs and LCVs due to their added height and weight. Rock and roll might be great to listen to but it's no fun when cornering.
If your vehicle leans excessively in corners, it's another tell-tale sign that the dampers are worn. Yet another clue is vibrations through the steering wheel. Often it is simply a wheel out of balance but it could well be one damper is more worn than the other, creating an uneven controlling of the suspension.
This will make your life a lot easier. It is costly, but more convenient since you can set it to automatically adjust. Once you have identified what dampers will affect certain parts of the room, it is time to figure out how to conduct the correct adjustments. You want to make sure that you know what to do to make hot or cold air flow through a particular room.
Again, some labeling is in order. There are two important rules that you need to remember here. First of all, cold air sinks and hot air rises. How does this affect the distribution of hot or cold air in your home? This means the attic is the hottest part of the house while the basement is the coldest. What you can do is to close the dampers that lead to the lower levels of the house. That means the bulk of the flow of air will be in the upper levels. It will naturally find its way down.
At least, this is true if you are cooling your house. If you want to heat your home, you do the opposite. When the AC is off and you fire up the furnace, you want to adjust the dampers so you have less airflow in the upper floors. The heat will rise and the right temperature will be distributed well throughout the house. In case you are implementing this for the first time, it might take a couple of days to determine if your adjustments are giving the desired effects.
Do not change the dampers immediately because it usually takes a few days for the right temperature to be felt. See if the rooms you want to be hotter or colder are turning out as you want it to. So far the tips provided earlier refer to adjustments you want to make during the summer and winter seasons. Make sure to put the necessary labels e. That way, adjusting these in the future will be easier. Obviously, you need to adjust the dampers when the season changes.
It helps to put an alert on your calendar so you are reminded to make the necessary changes before the house gets too hot or cold. And if you label your dampers correctly, you will not feel confused as to how you should change it. Even if you change houses, your efforts will be appreciated by the new owners.

The combination of pistons, valves and pressure achieves a normal balance. When the tyre hits a bump, though, it begins the suspension process by flexing a little, taking an initial bite out of the severity of the hit.
Damping rates can be controlled simply by varying the size of the valves in the main piston, for example. The problem with such a simple approach is that valves have maximum flow rates before they effectively stop working and the suspension almost locks for an instant.
Hit a bump hard and the damper will kick you in the ass. There are more complex options at the other end of the scale that use a combination of high-pressure nitrogen at the base of the damper and a floating piston to separate it from the oil chamber above.
The nitrogen helps reduce body roll, vibration and aeration of the oil, theoretically giving better small-bump response, a greater valving range and a suppler feel. A gas-charged damper is naturally way more expensive. Damping is a simple concept that can be executed in an ever-increasing array of ways.
