A gas spring
Abstract
According to an illustrative example of the invention a gas spring comprises adjacent one end of the cylinder two axially spaced sealing rings, namely an axially inner and an axially outer sealing ring. A lubricant chamber is defined axially between the axially inner and the axially outer sealing rings. The axially inner sealing ring is pressure-resistant against the elevated gas pressure within the working chamber such as to maintain the pressure of gas within the working chamber at a level exceeding the pressure within the lubricant chamber.
