Compression springs are the kind that comes to mind when most people try to picture a spring. These are open coil springs. They offer resistance to a compressive force. In other words they work in a "push" mode.
Their uses vary as much as the shapes and forms they come in- from engine valve springs to ball point pens.
Round wire is the most common material used to make this type of spring. Square, rectangular, or special shaped or sectioned wire is used in some cases.
Most of this type have the same diameter throughout the whole spring. These are known asstraight coil springs.
There are also the kind where the diameter of the spring varies throughout its length. These type are tapered or cone-shaped springs. Concave or convex forms are also used as well as a combination of both straight and tapered. These are specialized varieties of the standard compression spring.
The conical or tapered spring can be designed so that each coil nests wholly or partially into the adjacent larger coil. This gives the spring the ability to have its solid height no larger than one wire diameter.
Conical or tapered springs can be designed with a controlled increasing rate as each turn successively becomes inactive during deflection. The larger diameter coils collapse and become inactive first thus causing the pattern of an increasing rate.
A conical spring can be made to have a constant rate by creating the spring with a variable pitch. Putting a larger pitch in the larger OD coils and a smaller pitch in the smaller OD coils will force the spring to collapse all the coils at the same rate when compressed.
