Dashpot Damper Motors

What is a Dashpot?

There are several different types of damper motors that are commonly called dashpots. What these damper motors do is essentially resist a motion via friction. The result is a force applied in the opposite direction of the movement which is proportional to the velocity. The dashpot slows the motion and absorbs energy. These types of damper motors are most often used with a spring that helps to resist displacement of the components.

Linear and Rotary Types

There are two types of dashpot damper motors, known for their directional applications, which are linear and rotary. The linear dashpot counters the force applied in one single direction. This linear type of system is very popular in numerous everyday items. These range from almost anything electronic, especially if the device has external moving parts, to shock absorbers in cars. Rotary dashpot damper motors work differently since their resistant movement must be applied in a circular pattern. The rotary dashpots can most often be found in machines and equipment that needs to turn quickly.

Modern Uses

The installation of dashpot damper motors on modern machinery allows for precise control of the device even when there are extreme amounts of force being applied to create the movement. However, without this kind of technology, all the countless industrial and household products we use everyday would need repair and maintenance much more often than they do. This is due to the fact that the internal components of the machine would inadvertently collide against each other more frequently than normal, causing accelerated wear and tear.

Linear dashpots can be made inexpensively, yet still provides an effective balancing measure that is durable and will last years or even decades. To explain further what a dashpot damper motor does, let's look at one of the most common and familiar examples of what it's used for; the hydraulic cylinder in an automobile shock absorber.

Usually, what a dashpot does is cushion impact. The linear dashpot behaves like a heavily dampered spring that is ready to be sprung. It's one way mechanical bypass sets up that allows for very fast and unrestricted movement in one direction and then a slow motion implemented by the dashpot damper motor, in the opposite direction. It's this unrestricted movement that's accomplished through hydraulic dashpot damper motors, that allows the shock absorbing mechanism to move without fluid constriction.

Military Usage

Dashpots are also commonly used in carburetors. This is necessary to allow the throttle lever to return to its regular position by creating a slow or cushioning effect just before the throttle fully closes. This is important because without a slow close there could be a sudden deceleration, as well as, a sudden blast of exhaust emissions both of which are undesirable for obvious reasons. There are even dashpot damper motors that are able to control extremely large forces and high speeds. For example, there are huge dashpots that are designed specifically to stop and slow down the catapult system used on carrier decks transporting military aircraft across the ocean.
