A gas spring is a type of spring that, unlike a typical metal spring, uses a compressed gas, contained in a cylinder and compressed by a piston, to exert a force. Common applications include automobiles (where they are incorporated into the design of struts that support the weight of hatchback doors while they are open) and office chairs. They are also used in furniture, medical and aerospace applications. Much larger gas springs are found in machines that are used in industrial manufacturing (the press tooling industry), where the forces they are required to exert often range from 2500N to 400,000N (Forty tonnes).
To properly use gas springs in even the simplest application, users should understand how they work and how a gas spring can be modified to meet specific operating requirements. All of the topics covered in our Gas Springs Resources represent a gas spring feature or characteristic that can be modified to enhance gas spring performance. The information on gas springs in these sections apply equally to compression gas springs, tension or traction gas springs, and locking and stainless steel gas springs.

Famous quotes containing the words gas and/or spring:
“Shielded, what sorts of life are stirring yet:
Legs lagged like drains, slippers soft as fungus,
The gas and grate, the old cold sour grey bed.”
—Philip Larkin (1922–1986)
“The partridge and the rabbit are still sure to thrive, like true natives of the soil, whatever revolutions occur. If the forest is cut off, the sprouts and bushes which spring up afford them concealment, and they become more numerous than ever. That must be a poor country indeed that does not support a hare. Our woods teem with them both.”
—Henry David Thoreau (1817–1862)
